TURNS

Objective

The CFII candidate will demonstrate instructional knowledge and teaching ability for helicopter instrument turns by explaining the aerodynamic and procedural concepts of standard-rate and half-standard-rate turns, conducting demonstration flights using both full and partial panel, analyzing common student errors, and meeting the practical test standards outlined in FAA-S-8081-9E, Task CFII.VI.B. Upon completion, the candidate will exhibit the ability to teach a helicopter instrument student to perform turns to headings with precise bank control, accurate roll rates, coordinated control inputs, and proper trim technique while maintaining altitude ±100 feet, airspeed ±10 knots, bank ±5°, and rolling out on assigned headings ±10°.

Content

The Standard Rate Turn — Foundation Concept

The standard rate turn is the foundation of instrument flight navigation, defined as 3° per second of heading change. This produces a 360° turn in exactly two minutes, making mental calculation of turn anticipation straightforward for holding patterns, procedure turns, and course intercepts. In helicopters, the standard rate turn provides optimal navigation precision without excessive maneuvering in the confined spaces often encountered during low-altitude IFR operations.

Teaching Method: Begin with the “clock face” analogy. “Imagine your heading indicator as a clock. Standard rate means the heading bug moves from 12 to 1 in ten seconds — that’s 30° in ten seconds, or 3° per second. If you need to turn from 090° to 180°, that’s 90° of turn, which takes 30 seconds at standard rate.”

Calculating Bank Angle for Standard Rate

The relationship between true airspeed and bank angle determines the rate of turn. The rule of thumb formula is:

Bank Angle = (TAS ÷ 10) + 7

However, for helicopter IFR operations, most training and actual flight occurs at speeds where this simplifies considerably:

• At 60 knots TAS: (60 ÷ 10) + 7 = 13° bank
• At 80 knots TAS: (80 ÷ 10) + 7 = 15° bank
• At 90 knots TAS: (90 ÷ 10) + 7 = 16° bank
• At 100 knots TAS: (100 ÷ 10) + 7 = 17° bank

Most training helicopters fly instrument approaches between 60-90 knots, meaning standard rate turns typically require 13-16° of bank. This is significantly less than the 20-25° banks common in fixed-wing standard rate turns due to the helicopter’s slower cruise speeds.

Teaching Method: “Your R22 cruises about 90 knots under the hood. That means you’re looking for about 15° bank for standard rate — half the bank you’d use in a steep turn, but enough to feel definite control pressure. Watch the turn coordinator. The wing tip should align exactly with the index mark. That’s your immediate feedback that you’re at standard rate, and the bank angle on the attitude indicator should confirm roughly 15°.”

Half-Standard Rate Turns

A half-standard rate turn produces 1.5° per second of heading change, doubling the time required for any given heading change. This slower turn rate is essential for:

1. Precision approach final segments where turn radius must be minimized
2. Holding pattern entries when timing must be exact
3. High workload phases when dividing attention between navigation and communication
4. Student training progression before advancing to standard rate

Bank angle for half-standard rate is approximately half that required for standard rate:

• At 60 knots: 7-8° bank
• At 90 knots: 8-9° bank

Teaching Method: “Half-standard rate is your ‘thinking turn.’ Use it when you need more time to brief an approach plate, copy a clearance, or set up your radios. The turn coordinator wing tip should be halfway between center and the standard rate index. This gives you 60 seconds to turn 90° instead of 30 seconds — double the time to get organized.”

Full Panel Turn Technique and Procedure

The full panel turn requires systematic cross-check and coordinated control application. The standard teaching sequence follows the control-performance concept using primary and supporting instruments for each flight parameter.

Entry Procedure

1. Establish reference conditions — Level flight, trimmed, on-speed, heading confirmed
2. Determine turn direction and degree — Mental calculation of degrees to turn and seconds required
3. Initiate coordinated control inputs:
   • Cyclic: Smoothly apply lateral cyclic in direction of turn to establish bank angle
   • Pedals: Apply coordinating pedal pressure (right pedal for right turn in American helicopters) to prevent yaw
   • Collective: Slight increase to compensate for vertical component of lift lost to horizontal turn component
4. Cross-check confirms:
   • Attitude indicator shows target bank angle (primary bank)
   • Turn coordinator shows standard rate wing-tip alignment (primary rate)
   • Altimeter and VSI remain stable (primary pitch)
   • Airspeed remains on target ±10 knots (supporting pitch)
   • Heading indicator begins movement at 3° per second (supporting bank/rate)
   • Ball remains centered (coordination check)

During Turn

Primary cross-check pattern during established turn:

Attitude indicator → Turn coordinator → Altimeter → Heading indicator → Attitude indicator

1. Attitude indicator — Verify bank angle remains constant. This is primary bank during the turn.
2. Turn coordinator — Verify wing tip remains on index for standard rate (or half-index for half-standard). This confirms rate of turn.
3. Altimeter — Verify altitude constant. Adjust collective as needed.
4. VSI — Confirm zero vertical speed trend.
5. Heading indicator — Monitor progress toward rollout point.
6. Airspeed — Verify on-speed. Adjust cyclic pitch as needed.
7. Ball — Verify centered. Adjust pedal pressure.

Trim Technique During Turn: Trim is control-pressure relief, not a flight control. In helicopters, most instrument turn trim application involves:

• Collective friction to hold altitude correction inputs
• Pedal trim (if equipped) to relieve foot pressure during extended turns
• Cyclic friction is generally NOT used during turns as bank angle requires active monitoring

Teaching Method: “Trim relieves pressure, it doesn’t fly the helicopter. If you’re holding right pedal pressure for 30 seconds in a right turn, use pedal trim to center your foot. Release it before rollout. Never trim the cyclic during a turn — you need immediate feedback through control pressure to sense bank changes.”

Rollout Procedure

Standard rollout anticipation is one-half the bank angle in degrees. For a 15° bank standard rate turn, anticipate rollout by 7-8° before the desired heading.

1. Begin rollout at calculated lead point (bank angle ÷ 2)
2. Coordinated control inputs:
   • Cyclic: Smoothly neutralize bank, rolling wings level
   • Pedals: Reduce coordinating pedal pressure
   • Collective: Slight decrease to compensate for regained vertical lift component
3. Cross-check confirms:
   • Heading indicator stops on target heading ±10° (primary bank during rollout)
   • Attitude indicator shows wings level (supporting bank)
   • Turn coordinator shows centered wings (primary rate)
   • Altimeter stable (primary pitch)
   • Ball centered throughout (coordination)
4. Re-trim to relieve any residual control pressures

Teaching Method: “Rollout lead is half your bank. Fifteen-degree bank means start rolling out eight degrees early. Count: three-six-zero, three-six-one, three-six-two… start rolling out at three-six-two for a three-seven-zero heading. The heading indicator becomes your primary bank reference during rollout because you’re trying to STOP on a number. Roll smoothly through level — same rate out as you rolled in.”

Partial Panel Turn Technique and Procedure

Partial panel turns simulate vacuum system failure, removing the attitude indicator and heading indicator from the scan. This requires fundamental instrument flying skills using only the turn coordinator, magnetic compass, altimeter, airspeed indicator, and VSI.

Critical Concepts for Teaching Partial Panel Turns

Turn Coordinator as Attitude Reference: The turn coordinator becomes the only direct bank attitude reference. The miniature wing tips show bank direction and rate, but NOT the precise bank angle. The pilot must:

1. Establish bank by referencing the wing tip to the standard rate index
2. Maintain bank using turn coordinator trend information
3. Monitor performance using compass, altimeter, and airspeed

Magnetic Compass Turns: The magnetic compass is the only heading reference during partial panel operations, but it exhibits multiple errors during turns:

• Northerly Turning Error (ANDS): Accelerate North, Decelerate South

  • When turning through north, compass lags behind actual heading
  • When turning through south, compass leads actual heading

• Acceleration Error (ANDS):

  • When accelerating on east/west headings, compass indicates turn toward north
  • When decelerating on east/west headings, compass indicates turn toward south

• Oscillation and Lag:

  • Compass swings erratically during turns
  • Settles only in wings-level, constant-speed flight

Teaching Method: “ANDS — Accelerate North, Decelerate South. The compass lies during turns, especially through north and south. In the northern hemisphere, if you’re turning TO north, the compass lags behind you. If you’re turning TO south, it leads you. You can’t trust the numbers you see DURING the turn — only wings level.”

Partial Panel Turn Procedure

Turns to North (and within 45° of north):

1. Calculate rollout lead: Normal lead (bank ÷ 2) PLUS undershoot for compass lag

   • Example: Turning right to 360° from 270°
   • 15° bank = 7° normal lead = 353° lead point
   • Add 15° undershoot for northerly turn = 338° rollout point
   • Roll out when compass shows 338°, settle on 360°

2. Control cross-check:

   • Turn coordinator — primary bank and rate
   • Magnetic compass — monitor for rollout point (unreliable during turn)
   • Altimeter — primary pitch
   • Airspeed — supporting pitch
   • VSI — trend information

Turns to South (and within 45° of south):

1. Calculate rollout lead: Normal lead (bank ÷ 2) MINUS overshoot for compass lead
   • Example: Turning left to 180° from 270°
   • 15° bank = 7° normal lead = 187° lead point
   • Subtract 15° overshoot for southerly turn = 202° rollout point
   • Roll out when compass shows 202°, settle on 180°

Turns to East or West (within 45° of 090° or 270°):

1. Use standard rollout lead (bank ÷ 2) with minimal adjustment
2. Compass is most reliable near east-west headings during turns
3. Verify no acceleration/deceleration to minimize errors

Teaching Method: “Partial panel turns are all about timing and patience. Get established in your turn using the turn coordinator — wing tip on the index. Then ignore the compass for 10 seconds. Let it settle into its swing pattern. Now monitor trend: is it approaching your target? When you get close — 20 degrees away — start thinking about rollout. Through north, roll out early and let it catch up. Through south, roll out late and let it settle back. Through east or west, trust your normal lead.”

Coordination of Controls and Trim

Coordination means harmonized use of all flight controls to produce a turn without slip or skid. The ball in the turn coordinator (or turn-and-slip indicator) provides immediate feedback:

Ball Position Indications:

• Centered: Coordinated flight — relative wind aligned with longitudinal axis
• Deflected to inside of turn: Skid — excessive pedal, insufficient bank
• Deflected to outside of turn: Slip — insufficient pedal, excessive bank

Helicopter-Specific Coordination Considerations:

Helicopters in right turns (American helicopters with counterclockwise main rotor) require:

• Right pedal input to counteract tail rotor thrust and prevent yaw to left
• Amount varies with collective setting (higher collective = more torque = more pedal needed)
• Amount varies with airspeed (translational lift effects change tail rotor effectiveness)

Left turns require:

• Less left pedal than expected because engine torque assists the turn
• May require slight RIGHT pedal to prevent over-rotation

Teaching Method: “The ball doesn’t lie — step on it. Ball right, need right pedal. Ball left, need left pedal. In helicopters, right turns need strong right pedal because torque tries to yaw you left. Left turns need less help — torque is working for you. The key is small corrections. Big pedal inputs just swap one coordination error for another.”

Trim Application in Turns:

1. Do NOT trim controls during the turn entry or rollout — changing control pressures provide feedback
2. DO trim extended turns (holding patterns, enroute navigation) to relieve sustained pressure
3. Release trim before rollout to avoid control lag
4. Trim for wings-level flight after rollout complete

Common Errors — Improper Cross-Check Procedures

Error: Fixation on single instrument (usually attitude indicator)

• Indication: Altitude deviations, airspeed variations, skidding/slipping turn
• Correction: Force scan pattern — “AI, TC, ALT, HI, back to AI” spoken aloud initially
• Teaching Method: “Your student’s head isn’t moving. That’s the first clue they’re fixated. Break the fixation: ‘What’s your altitude? What’s your rate of turn? What’s the heading?’ Force them to look at different instruments. If they can’t answer, they’re fixated.”

Error: Omission of instruments from scan

• Indication: Consistent oversight of specific parameter (usually VSI or ball)
• Correction: Forced include into verbal scan pattern, briefing card reminder
• Teaching Method: “Most students omit the ball and the VSI. Ball doesn’t make noise when you’re uncoordinated. VSI doesn’t shout when you’re drifting. You have to make checking them a habit. Call them out every scan: ‘Altitude, VSI, airspeed, ball.’”

Error: Emphasis on supporting instruments instead of primary instruments

• Indication: Chasing needles, over-controlling, inability to hold parameters
• Correction: Primary/supporting concept training, instrument coverage exercise
• Teaching Method: “The attitude indicator doesn’t tell you if your altitude is holding — the altimeter does. If you’re staring at the AI trying to judge altitude, you’re using a supporting instrument as primary. Look at what gives you the answer directly.”

Common Errors — Improper Bank Control During Roll-In and Roll-Out

Error: Abrupt, jerky entry into turn

• Indication: Altitude loss/gain, airspeed fluctuation, passenger discomfort
• Correction: Count roll rate — “One thousand one, one thousand two” to 15° bank
• Teaching Method: “Smooth is fast. Jerky control inputs in a helicopter waste energy and create secondary control problems. Roll into the turn like you’re stirring honey — deliberate, smooth, continuous. Two-second roll to 15° bank.”

Error: Overbanking initially, then correcting back

• Indication: Wings roll through desired bank, then back, then hunt for stability
• Correction: Bracket bank angle from below, trim visual reference on AI
• Teaching Method: “Your student rolls to 20°, then backs off to 10°, then hunts around 15°. They’re overcontrolling because they don’t have a picture. Give them a reference: ‘See the width of your thumb on the AI? That’s 15°. Roll TO that picture, then stop the roll.’”

Error: Late rollout resulting in overshoot

• Indication: Consistently passing through desired heading by 20-30°
• Correction: Increase rollout lead, mental calculation before turn
• Teaching Method: “They’re rolling out ON the heading instead of BEFORE it. Make them say out loud: ‘Turning to 090, rolling out at 098.’ If they can’t say the rollout number before the turn, they’re not planning ahead.”

Error: Early rollout resulting in undershoot

• Indication: Stopping 10-20° before desired heading
• Correction: Verify bank angle calculation, ensure full standard rate during turn
• Teaching Method: “Early rollouts mean one of two things: they’re using too much lead, or they’re not turning at standard rate. Check the turn coordinator — is the wing tip actually ON the index, or just close? Close doesn’t count.”

Error: Varying bank angle during turn

• Indication: Bank increases or decreases during turn, inconsistent rate
• Correction: Primary reference discipline, trim technique review
• Teaching Method: “The bank angle is wandering because they’re not using the attitude indicator as primary bank. They’re trying to ‘feel’ it or judge it by the turn coordinator. AI is primary bank IN the turn. Turn coordinator is primary RATE. Use both.”

Common Errors — Failure to Make Smooth, Precise Corrections

Error: Large, aggressive corrections

• Indication: Oscillations around desired bank, altitude, or heading
• Correction: “Half-bank angle” correction rule — make corrections using half the error
• Teaching Method: “If they’re 10° off bank, correct with 5° input. If they’re 100 feet high, use 50 feet per minute down. Overshoot corrections create oscillations. You fix a pendulum by dampening it, not swinging it harder.”

Error: Delayed recognition requiring large corrections

• Indication: Waiting until deviations are significant before correcting
• Correction: Trend analysis training, anticipation briefing
• Teaching Method: “Ask them: ‘Is your altitude holding or changing? Is your bank increasing or decreasing?’ Trend is more important than position. Catch the trend when it starts — a 20-foot deviation growing — not after it’s 100 feet.”

Error: No corrections when deviations are small

• Indication: Accepting 50-foot altitude deviations, 5° heading deviations as “close enough”
• Correction: Standards reinforcement, precision emphasis
• Teaching Method: “IFR isn’t about being close. It’s about being exact. Fifty feet high on an ILS in IMC might put you in the trees. Five degrees off course in a hold might put you in the mountain. Precise is safe.”

Common Errors — Uncoordinated Use of Controls

Error: Bank without pedal coordination

• Indication: Ball deflected throughout turn, slip or skid
• Correction: Simultaneous control input emphasis, “step on the ball” discipline
• Teaching Method: “They’re rolling in with cyclic but forgetting the pedals. Make them say it: ‘Cyclic right, pedal right, together.’ The controls move as a team, not one at a time.”

Error: Excessive or insufficient pedal for power/airspeed condition

• Indication: Need for constant pedal adjustment, inability to trim
• Correction: Collective-pedal relationship review, torque effect understanding
• Teaching Method: “More collective means more torque, means more right pedal in American helicopters. If they’re climbing in the turn and the ball goes left, they need more right pedal for the increased power. If they’re descending and the ball goes right, they need less right pedal. Pedal follows power.”

Error: Opposite pedal application (cross-control)

• Indication: Severe slip or skid, possible roll coupling
• Correction: Control direction review, direction of turn verification
• Teaching Method: “They’re turning right with left pedal. Stop the exercise. ‘Which way are we turning? Which pedal are you pressing? Are those the same direction?’ Slow down. Verbalize. Prevent the error before it becomes a habit.”

Common Errors — Improper Trim Technique

Error: Attempting to trim during turn entry or rollout

• Indication: Control lag, overshoot, inability to stop precisely on heading
• Correction: Trim timing discipline — trim only in established, stable flight
• Teaching Method: “Trim is for relieving pressure in stable flight, not for maneuvering. If you’re rolling in or rolling out, your hands should be on the controls feeling the pressures, not reaching for the trim. Trim after you’re established or after you’re wings level — never during the transition.”

Error: Over-trimming, eliminating control feedback

• Indication: Delayed error recognition, inability to sense deviations
• Correction: Pressure relief concept, trim as assistant not replacement
• Teaching Method: “If they trim until there’s zero pressure, they’ve trimmed away their feedback system. You WANT slight pressure — it tells you what the helicopter is doing. Trim until the pressure is comfortable, not until it’s gone.”

Error: Failure to release trim before rollout

• Indication: Bank angle continues past wings level, heading overshoot
• Correction: Pre-rollout discipline, clearing trim before control input
• Teaching Method: “If they trimmed pedals during a two-minute holding pattern turn, they need to release that trim before rollout. Otherwise, the trimmed pedal fights the rollout. Make trim release part of the rollout flow: approaching rollout point, release trim, then roll out.”

Error: Using trim instead of proper control input

• Indication: Attempting to change flight parameters with trim alone
• Correction: Primary controls for maneuvering, trim for pressure relief
• Teaching Method: “Trim doesn’t fly the helicopter — you do. If altitude is dropping, don’t reach for collective trim. Add collective, stabilize, THEN trim the new pressure. Control first, trim second.”

6. Answer evaluator questions with specific, regulation-referenced responses; provide examples from personal instructional experience; relate concepts to practical IFR operations.

Pre-Flight Briefing

1. Brief the training flight as if briefing an instrument student:

   • Objective: “Today we’re practicing standard rate and half-standard rate turns, full and partial panel, with emphasis on smooth control coordination.”
   • Setup: “We’ll climb to 3,500 feet in the practice area, establish level flight at 90 knots, and I’ll demonstrate each maneuver while explaining what I’m doing and why.”
   • Safety: “I have the flight controls. If you see conflicting traffic or we approach unusual attitudes, call them out immediately. Recovery procedure is: level the wings, adjust pitch, add power as needed.”
   • Standards: “We’re maintaining altitude plus or minus 100 feet, airspeed plus or minus 10 knots, bank plus or minus 5 degrees, and rolling out on assigned headings plus or minus 10 degrees.”

2. Calculate performance numbers for current aircraft weight and conditions:

   • Determine TAS at planned altitude and power setting

   • Calculate bank angle for half-standard rate turn
   • Brief expected control pressures based on power setting

3. Prepare for partial panel by explaining attitude indicator failure simulation method; brief use of remaining instruments; review compass error compensation.

Flight Demonstration — Full Panel Standard Rate Turns

1. Demonstrate turn entry with continuous narration:

   • “I’m level at 3,500 feet, 90 knots, on a heading of 180. I want to turn right to 270, which is 90 degrees of turn. At standard rate, that’s 30 seconds. My rollout lead is half my bank angle — I’m planning 15 degrees of bank, so I’ll roll out about 8 degrees early, at 262.”
   • “Rolling into the turn: smooth right cyclic to establish 15 degrees of bank on the attitude indicator, coordinating with right pedal to keep the ball centered, adding a touch of collective to maintain altitude as the vertical component of lift decreases.”
   • “Cross-checking: attitude indicator shows 15 degrees right bank — that’s primary bank. Turn coordinator wing tip is on the standard rate index — that confirms my rate of turn. Altimeter is steady at 3,500 — altitude’s holding. Heading indicator shows 185, 190, 195 — I’m turning at the right rate.”

2. Demonstrate established turn cross-check:

   • Verbalize scan pattern: “Attitude indicator — bank is 15 degrees, good. Turn coordinator — wing tip on the index, rate is standard. Altimeter — 3,500, holding. VSI — zero, no vertical trend. Airspeed — 90 knots, on target. Heading indicator — approaching 260. Ball — centered, coordinated.”
   • Make small corrections with narration: “I’m drifting 20 feet high, reducing collective slightly to arrest the climb. Bank angle decreased to 13 degrees, adding a touch of right cyclic to bring it back to 15.”

3. Demonstrate rollout with continuous narration:

   • “Approaching 262, eight degrees before my target of 270. Rolling out now: smooth left cyclic to level the wings, reducing right pedal pressure, reducing collective slightly as I regain the vertical lift component.”
   • “Heading indicator is now primary bank — I’m trying to stop on 270. Turn coordinator shows decreasing right turn, now centered. Attitude indicator shows wings level. Heading indicator shows… 268, 269, 270. On heading.”
   • “Altimeter check — 3,490. I’m 10 feet low, adding a touch of collective. Trimming out the control pressures now that I’m stabilized.”

4. Perform multiple turn demonstrations to various headings, both directions; maintain teaching narration throughout; point out primary instrument transitions between phases; emphasize smooth, coordinated control inputs.

Flight Demonstration — Half-Standard Rate Turns

1. Explain use case before demonstrating:

   • “Half-standard rate gives us more time during high workload phases. If I’m being vectored for an approach and need to copy a complex clearance, I might request half-standard rate turns so I have more time to write and read back.”
   • “Bank angle for half-standard is approximately half what we used for standard rate. Instead of 15 degrees, I’m targeting about 7-8 degrees.”

2. Demonstrate half-standard rate turn with narration:

   • “Turning left from 090 to 360, which is 90 degrees of turn. At half-standard rate, that’s 60 seconds instead of 30. Rolling in with about 7 degrees of bank. Turn coordinator wing tip should be halfway between center and the standard rate index.”
   • “Cross-check: attitude indicator shows 7 degrees left bank — primary bank. Turn coordinator shows the wing tip halfway to the index — that’s half-standard rate. Altimeter steady. Heading indicator turning slowly — 085, 080, 075.”
   • “This slower turn gives me more time to divide my attention. Notice how the scan is easier to maintain because the heading isn’t changing as fast.”

3. Demonstrate transition from standard to half-standard rate during a single turn:

   • “I’m established in a standard rate turn. Now reducing bank from 15 to 7 degrees — turn coordinator wing tip moves from the index to halfway. The heading indicator slows its movement. I now have twice as much time to complete the turn.”

Flight Demonstration — Partial Panel Turns

1. Set up partial panel configuration:

   • “I’m covering the attitude indicator to simulate a vacuum failure. Now my primary instruments are the turn coordinator for bank and rate, the magnetic compass for heading, the altimeter for pitch, and the airspeed indicator for pitch trend.”
   • “The heading indicator is also unusable — in a real vacuum failure, it would tumble or precess. I’m relying entirely on the magnetic compass.”

2. Demonstrate compass turn through north:

   • “Current heading on compass is 270. I want to turn right to 360. The compass will lag during this northerly turn because of ANDS — Accelerate North means the compass lags when turning toward north.”
   • “My normal rollout lead is 7 degrees for 15-degree bank. But I need to add about 15 degrees of undershoot for the compass lag. So I’ll roll out when the compass shows approximately 338, and it will settle on 360.”
   • “Rolling into the turn: turn coordinator wing tip on the standard rate index. Ignoring the compass for the first 10 seconds — it’s swinging wildly. Maintaining altitude with reference to altimeter and airspeed.”
   • “Compass is now swinging through 320, 315, 310. As I approach 345, I’m monitoring more closely. Compass shows 340, 338 — rolling out now. Wings level on the turn coordinator. Compass is settling… 355, 358, 360. On heading.”

3. Demonstrate compass turn through south:

   • “Turning left from 090 to 180, which is 90 degrees. The compass will lead during this southerly turn — Decelerate South means it shows more turn than I’ve actually made.”
   • “Normal rollout lead is 7 degrees, which would be 187. But I need to subtract about 15 degrees of overshoot for the compass lead. I’ll roll out when the compass shows approximately 202, and it will settle back to 180.”
   • “Established in the turn, turn coordinator on standard rate. Compass swinging through 070, 050, 030. Approaching the rollout point — compass shows 210, 205, 202 — rolling out. Compass is settling… 188, 184, 180. On heading.”

4. Demonstrate compass turn through east or west:

   • “Turns through east or west headings have minimal compass error, especially if I maintain constant airspeed to avoid acceleration error. Rolling out using standard lead, approximately 7 degrees before 090.”
   • “The compass is more reliable here. I can trust the numbers I see during the turn much more than during north or south turns.”

5. Explain limitations:

   • “Partial panel turns require patience. I can’t rush the compass. I have to let it stabilize after rollout to verify I’m on heading. In IMC with partial panel, I’d be requesting no-gyro vectors from ATC — they’d say ‘turn right,’ ‘stop turn’ rather than giving me headings to fly.”

Error Analysis and Correction Demonstration

The evaluator (DPE) will simulate common student errors, and the candidate must identify, diagnose, and correct them using effective instructional techniques.

1. Recognize and correct fixation errors:

   • DPE simulates: Student stares at attitude indicator, altitude drifts 150 feet low
   • Candidate response: “I notice you’re focusing entirely on the attitude indicator. What’s your altitude? [Student doesn’t know] That’s fixation. You need to include the altimeter in your scan. Let’s practice: attitude indicator, turn coordinator, altimeter, heading indicator — say them out loud as you look at each one.”

2. Recognize and correct bank control errors:

   • DPE simulates: Student rolls into turn quickly, overshoots to 25° bank, corrects back to 10°, hunts around 15°
   • Candidate response: “You’re overcontrolling the bank. Roll more slowly — count two seconds from wings level to 15 degrees. Think of it as one smooth motion, not a quick jab. Watch the attitude indicator: see this reference? That’s your target. Roll TO it, not THROUGH it.”

3. Recognize and correct coordination errors:

   • DPE simulates: Student turns right without right pedal, ball deflects left
   • Candidate response: “Look at the ball — it’s deflected left. That means you’re in a slip. Step on the ball: ball left means you need left pedal. Wait — you’re turning right, so you need RIGHT pedal, not left. Right turn means right pedal in this helicopter. Let’s try again: rolling right, and simultaneously adding right pedal. There — ball’s centered now.”

4. Recognize and correct rollout errors:

   • DPE simulates: Student consistently overshoots heading by 20°
   • Candidate response: “You’re overshooting every heading. That tells me you’re rolling out too late. What’s your rollout lead? [Student says ‘half the bank’] Correct — half of 15 is about 7 or 8 degrees. Are you actually rolling out 8 degrees early? Let’s try this: you’re turning to 090. Tell me your rollout heading BEFORE you start the turn. [Student calculates] Good — 098. Now watch the heading indicator and start your rollout AT 098, not AFTER it.”

5. Recognize and correct trim errors:

   • DPE simulates: Student attempts to trim cyclic during rollout
   • Candidate response: “Stop — don’t trim during the rollout. You’re in a dynamic maneuver. You need to feel the control pressures to give you feedback. Trim AFTER you’re wings level and stabilized. Right now, hands on the controls, feel what the helicopter is telling you through the cyclic and pedals.”

Post-Flight Instructional Debrief

1. Conduct self-critique:

   • “My ground instruction covered the aerodynamic principles and procedures effectively. I used the bank angle formula and demonstrated the math clearly.”
   • “During the flight demonstration, my teaching narration was continuous and specific. I identified primary and supporting instruments throughout each phase.”
   • “On the partial panel demonstration, I could have been more precise in my compass error explanations. I should have drawn the ANDS diagram on my kneeboard for reference.”

2. Answer evaluator scenario questions:

   • Example: “Your student consistently shows good bank control but poor altitude control during turns. What’s your diagnosis and correction?”
   • Candidate response: “That indicates they’re fixating on bank and rate instruments while omitting the altimeter and VSI from their scan. I’d have them verbalize their scan pattern, specifically calling out altitude every third instrument. I’d also emphasize the collective-altitude relationship: turns require a slight collective increase to maintain altitude because some lift is diverted to horizontal turning force.”

3. Demonstrate teaching knowledge:

   • Explain how to progress a student from half-standard to standard rate turns
   • Describe how to introduce partial panel incrementally (first straight-and-level, then turns to cardinal headings, then any heading)
   • Discuss risk management: recognizing when a student is task-saturated and needs to reduce turn rate or discontinue partial panel training
   • Reference specific PTS standards and explain how to measure student achievement against them

Student Actions

In this practical test scenario, the “student” is the DPE evaluating the CFII candidate’s instructional ability. The DPE will:

1. Receive ground instruction as if learning instrument turns for the first time or reviewing for proficiency; ask clarifying questions typical of instrument students; request examples or additional explanation when concepts are unclear.

2. Observe flight demonstrations while the candidate narrates teaching points; evaluate whether the candidate’s explanations are clear, accurate, and appropriately sequenced; verify that the candidate demonstrates while explaining (not one then the other).

3. Simulate common student errors when directed by the candidate during error analysis portion:

   • Fixation on single instrument when cued
   • Improper bank control (overshoot, undershoot, hunting)
   • Uncoordinated control inputs (skid or slip)
   • Poor rollout technique (early, late, abrupt)
   • Improper trim technique (wrong timing, over-trimming)

4. Respond to corrections provided by the candidate; demonstrate improvement when effective instruction is given; continue error if instruction is unclear or ineffective (testing candidate’s ability to adapt teaching method).

5. Ask scenario questions during ground instruction and post-flight debrief:

   • “Why does bank angle decrease when airspeed increases for the same rate of turn?”
   • “When would I use half-standard rate instead of standard rate?”
   • “How do I know if I’m coordinated without looking at the ball?”
   • “What happens to my turn if I lose the vacuum system in IMC?”

6. Evaluate teaching effectiveness:

   • Was the instruction clear and organized?
   • Did the candidate demonstrate mastery of content?
   • Were errors correctly diagnosed and effectively corrected?
   • Did the candidate maintain a professional, encouraging instructional tone?
   • Were safety considerations emphasized appropriately?

Completion Standards

The lesson is complete when the CFII candidate meets all performance standards outlined in FAA-S-8081-9E, Task CFII.VI.B. The evaluator will determine that the candidate has demonstrated instructional competency when the following criteria are met:

Knowledge Demonstration Standards

1. Explains the relationship between true airspeed and bank angle for standard rate turns using the formula (TAS ÷ 10) + 7, with accurate calculations for helicopter IFR speeds (60-100 knots); demonstrates mental math proficiency; provides clear explanation understandable to instrument students.

2. Teaches full panel turn techniques with complete coverage of entry procedure (coordinated control inputs, primary instrument identification), established turn cross-check (systematic scan pattern, instrument interpretation), and rollout procedure (lead calculation, coordinated recovery, primary instrument transition); explanations are logical, sequential, and supported by aerodynamic principles.

3. Teaches partial panel turn techniques with accurate explanation of magnetic compass errors (ANDS, acceleration error, oscillation), correct rollout lead calculations for northerly turns (undershoot by 15°), southerly turns (overshoot by 15°), and east/west turns (standard lead); demonstrates mental calculation process clearly.

4. Explains coordination of controls and trim specific to helicopters, including torque effects on pedal requirements, proper timing for trim application (not during entry or rollout), and relationship between collective setting and pedal pressure; distinguishes between pressure relief (correct) and eliminating control feedback (incorrect).

5. Identifies and teaches correction for all common errors:

   • Improper cross-check procedures (fixation, omission, wrong primary instruments)
   • Improper bank control (abrupt entry, overbanking, hunting, early/late rollout)
   • Failure to make smooth, precise corrections (over-correction, delayed recognition, accepting deviations)
   • Uncoordinated use of controls (skid, slip, cross-control, improper pedal pressure)
   • Improper trim technique (timing errors, over-trimming, using trim to maneuver)

Flight Demonstration Standards

The candidate demonstrates and simultaneously explains turns while maintaining:

1. Altitude: ±100 feet from assigned altitude throughout all phases of turn
2. Airspeed: ±10 knots from assigned airspeed
3. Bank angle: ±5° from desired bank (standard rate or half-standard rate)
4. Heading rollout: ±10° from assigned heading
5. Coordination: Ball within one-half ball width of center throughout turn
6. Rate of turn: Turn coordinator wing tip aligned with standard rate index (±width of index) for standard rate turns, or halfway between center and index for half-standard rate turns

Flight demonstrations include:

• Minimum two full panel standard rate turns to assigned headings, both directions
• Minimum one full panel half-standard rate turn with explanation of application
• Minimum three partial panel compass turns: one through north (demonstrating undershoot compensation), one through south (demonstrating overshoot compensation), one through east or west (demonstrating minimal error)
• Continuous teaching narration throughout all demonstrations — silence indicates failure to demonstrate instructional ability
• Proper instrument cross-check verbalization identifying primary and supporting instruments for each phase

Error Analysis Standards

The candidate correctly:

1. Identifies simulated student errors within 15 seconds of error initiation (demonstrates observational skill necessary for flight instruction)
2. Diagnoses root cause of error (e.g., fixation vs. improper technique vs. misunderstanding)
3. Prescribes specific, effective correction using appropriate teaching techniques (explanation, demonstration, guided practice, or positive transfer)
4. Verifies error correction by observing student performance improvement

Minimum acceptable performance: 4 out of 5 simulated errors correctly identified, diagnosed, and corrected with effective instruction.

Instructional Technique Standards

Throughout ground and flight instruction, the candidate:

1. Maintains professional, encouraging tone — builds student confidence while maintaining standards
2. Uses clear, concise language — avoids jargon without definition, speaks at student comprehension level
3. Sequences instruction logically — simple to complex, known to unknown
4. Provides specific examples — relates concepts to practical IFR operations
5. Checks student understanding — asks verification questions, requests student explanations
6. Adapts to student learning pace — recognizes confusion and adjusts teaching method
7. Emphasizes safety — identifies risks, teaches hazard recognition, promotes safe decision-making

Disqualifying Performance

The following constitute failure of Task CFII.VI.B:

• Inability to explain bank angle/TAS relationship or incorrect formula application
• Failure to maintain altitude within ±100 feet during any demonstrated turn
• Exceeding ±10 knots airspeed tolerance during turn demonstration
• Rolling out more than ±10° from assigned heading on more than one turn
• Uncoordinated flight (ball deflection exceeding one ball width) sustained for more than 5 seconds
• Incorrect compensation for compass errors on partial panel turns (northerly or southerly turn rollout errors exceeding 20°)
• Failure to provide continuous teaching narration during flight demonstrations (silence for more than 10 consecutive seconds)
• Inability to identify or correct majority of simulated student errors
• Unsafe flight operations or violation of PTS risk management elements
• Inability to answer evaluator knowledge questions with correct, regulation-based responses

Evaluator Assessment Method

The DPE will assess completion using:

1. Direct observation of candidate teaching behavior and flight performance
2. Oral questioning to verify depth of knowledge beyond scripted presentation
3. Scenario evaluation of candidate’s error analysis and correction techniques
4. Measurement against specific PTS tolerances for flight parameters
5. Professional judgment of overall instructional competency and readiness to teach instrument students

The standard is not perfection — it is instructional competency sufficient to safely and effectively teach helicopter instrument students to perform turns to PTS standards. The candidate must demonstrate they can transfer knowledge, recognize and correct errors, and maintain safe flight operations while teaching.
