The candidate will effectively explain and demonstrate proper control technique, power-pitch relationships, common student errors, and correction methods. Upon completion, the candidate will meet the teaching standards of PTS Task CFII.VI.E, demonstrating the ability to teach a student pilot to perform constant rate climbs and descents while maintaining altitude ±100 feet during level-offs, airspeed ±10 knots, heading ±10°, bank angle ±5°, and selected vertical speed ±100 feet per minute.

Content

Introduction to Constant Rate Climbs and Descents

Constant rate climbs and descents are fundamental instrument maneuvers that allow helicopter pilots to execute published instrument procedures with precision. Unlike cruise flight where altitude is relatively constant, or unlike steep approaches where rate of descent varies, these maneuvers require maintaining a specific vertical speed—typically 500 feet per minute—while controlling all other flight parameters. This skill directly applies to IFR departures, approach segments, holds, and any clearance requiring “climb and maintain” or “descend and maintain” altitudes.

Teaching this maneuver requires emphasizing that helicopters respond differently than fixed-wing aircraft. Power changes produce immediate vertical responses, but also create yaw and sometimes lateral drift tendencies. The helicopter’s relatively low inertia means it will accelerate or decelerate quickly—helpful for responsiveness, but requiring disciplined scan and light control inputs.

Power-Pitch Relationship in Helicopters

The foundational concept for constant rate flight is the power-pitch relationship: power controls rate of climb or descent, pitch controls airspeed. This is a reversal of what many students initially expect, and it’s critical for instrument flight instruction.

When teaching this concept, use the analogy of an elevator: pulling collective (adding power) makes you go up at a rate determined by how much power you add. The cyclic (pitch attitude) determines whether you’re going up fast and slow, or up gently and fast. In helicopters, this relationship is even more direct than in airplanes because of the immediate rotor thrust response.

For climbs: increasing collective increases vertical speed. If the nose pitches up due to the power addition, airspeed will decrease. To maintain cruise airspeed during the climb, slight forward cyclic pressure counteracts this tendency.

For descents: decreasing collective increases vertical speed downward. The nose may drop, increasing airspeed. Slight aft cyclic maintains the target airspeed during descent.

The instructor must teach students to make these control inputs smoothly and simultaneously, not sequentially. The error pattern “add power, wait, trim” creates altitude and airspeed oscillations that compound rapidly in instrument conditions.

Full Panel Entry Procedures

Entry into Constant Rate Climb

From level cruise flight, establish the climb in three simultaneous actions:

1. Power: Increase collective to achieve the target vertical speed (typically +500 fpm). In most training helicopters, this is approximately 2-3 inches of manifold pressure increase from cruise power.

2. Pitch: Apply forward cyclic pressure to maintain cruise airspeed or target climb airspeed. The attitude indicator should show approximately 5-7° nose-up attitude for most light helicopters, but airspeed is the primary reference.

3. Trim: Add left pedal to counteract increased torque effect. Verify coordination with slip-skid indicator centered.

The vertical speed indicator becomes the primary instrument for vertical performance once the climb is stabilized. Cross-check with altimeter trend and attitude indicator to verify the rate is sustainable.

Teaching emphasis: Students will initially fixate on the VSI and neglect airspeed. Teach the scan pattern: VSI for rate verification, airspeed indicator for pitch correction, attitude indicator for trend information, altimeter for progress toward target altitude.

Entry into Constant Rate Descent

From level cruise flight:

1. Power: Decrease collective to achieve target descent rate (typically -500 fpm). This is usually 2-3 inches manifold pressure reduction, but may require more in helicopters with low disk loading.

2. Pitch: Apply aft cyclic pressure to maintain cruise airspeed or target descent airspeed. Attitude may be nearly level or slightly nose-down depending on the helicopter.

3. Trim: Add right pedal to counteract decreased torque. The amount is often minimal but necessary for coordinated flight.

Teaching emphasis: Many students reduce power too gradually, creating a slow, mushing descent. Teach decisiveness in the power reduction, then immediate airspeed correction with cyclic.

Constant Rate Turns (Climbing and Descending)

Once the climb or descent is stabilized, adding a turn increases workload significantly. The bank angle should be limited to standard rate (3° per second) or half-standard rate in most training scenarios.

During climbing or descending turns, the helicopter requires additional collective to maintain vertical speed due to increased total lift requirement. The amount varies with bank angle—at 15° bank, approximately 3-5% additional power compensates for the vertical lift loss.

Procedure for climbing turn:

1. Establish stabilized constant rate climb
2. Roll into standard-rate turn using attitude indicator and turn coordinator
3. Increase collective slightly to maintain vertical speed
4. Adjust pitch (cyclic) to maintain airspeed
5. Adjust pedals for coordination
6. Scan: VSI primary for vertical, turn coordinator primary for bank, airspeed indicator primary for pitch

Procedure for descending turn:

1. Establish stabilized constant rate descent
2. Roll into standard-rate turn
3. Increase collective slightly (reduce the descent power) to maintain descent rate—may seem counterintuitive
4. Adjust pitch to maintain airspeed
5. Scan continuously across all instruments

Teaching emphasis: Students will lose 100-200 fpm in turns if they don’t anticipate the power requirement. Teach the habit of adding “a touch of collective” when rolling into any turn from a climb or descent.

Level-Off Procedures

Level-Off from Constant Rate Climb

The level-off must begin 10% of the vertical speed before reaching target altitude. For a 500 fpm climb, start the level-off 50 feet early (if climbing to 3,000 feet, begin at 2,950 feet).

Procedure:

1. At lead altitude, simultaneously reduce collective to cruise power setting and lower nose to cruise pitch attitude
2. Adjust pedals for reduced torque
3. Allow airspeed to increase to cruise speed
4. Fine-tune collective for altitude, cyclic for airspeed
5. Trim for hands-off flight

Common teaching error: Instructors often say “start leveling off at 50 feet before.” This creates student confusion about what “leveling off” means. Be specific: “At 50 feet before your altitude, reduce power to cruise and lower the nose to level. The helicopter will take the remaining 50 feet to finish climbing and stabilize.”

The analogy: stopping a car. You don’t wait until the stop sign to begin braking. You begin braking early so you arrive at the sign with zero speed.

Level-Off from Constant Rate Descent

Lead point is the same: 10% of vertical speed, typically 50 feet before target altitude.

Procedure:

1. At lead altitude, simultaneously increase collective to cruise power and raise nose to cruise pitch attitude
2. Adjust pedals for increased torque (left pedal)
3. Allow airspeed to decrease to cruise speed if descending at high speed
4. Fine-tune collective for altitude, cyclic for airspeed
5. Trim

Teaching emphasis: Students often level off early from descents and late from climbs. Teach that the lead point is the same because the correction actions take similar time—it’s about deceleration rate, not direction.

Partial Panel Procedures

Partial panel assumes loss of attitude indicator and heading indicator, leaving the turn coordinator, airspeed, altimeter, VSI, and magnetic compass.

Partial Panel Climbs

Without the attitude indicator, the turn coordinator becomes the primary bank reference, and pitch must be inferred from airspeed trend and VSI.

Procedure:

1. Increase collective for target vertical speed
2. Reference turn coordinator wings-level
3. Monitor airspeed—if decreasing, apply forward cyclic; if increasing, apply aft cyclic
4. Verify VSI shows target rate
5. Trim for coordinated flight using ball
6. Scan: VSI primary for vertical, airspeed primary for pitch, turn coordinator primary for bank

Teaching emphasis: Students must learn to trust the performance instruments. Without attitude information, they cannot “feel” the nose position. Teach the scan pattern: “VSI shows I’m climbing at 500, airspeed shows I’m at 80 knots and stable, ball shows I’m coordinated—everything is correct even though I can’t see the nose attitude.”

Use the analogy of driving in fog: you know you’re going uphill because the speedometer shows you’re slowing (if you don’t add power) and the altimeter shows increasing altitude. You don’t need to see the hill to know you’re climbing it.

Partial Panel Descents

Same instrument substitutions apply.

Procedure:

1. Reduce collective for target descent rate
2. Reference turn coordinator wings-level
3. Adjust cyclic based on airspeed: too fast, pull back; too slow, push forward
4. Verify VSI at target rate
5. Trim using ball

Teaching emphasis: In descents, students often let airspeed run away because they’re focused on the VSI. Teach the discipline: “VSI tells you if you’re descending. Airspeed tells you if you’re doing it at the right speed. Both are required.”

Partial Panel Turns

Combining climbs/descents with turns on partial panel significantly increases workload. The turn coordinator provides bank information, but not rate of turn directly. Students must reference both the turn coordinator (for standard rate indication) and the magnetic compass (for heading, with lead/lag compensation).

Procedure for climbing/descending turns:

1. Establish stabilized climb or descent on partial panel
2. Roll into turn using turn coordinator—needle width for standard rate
3. Increase collective slightly to maintain vertical speed
4. Adjust cyclic to maintain airspeed
5. Adjust pedals for ball centered
6. Begin rollout using magnetic compass with appropriate lead (30° for turns to north/south, 15° for turns to east/west)

Common Student Errors and Corrections

Error: Failure to Use Proper Power Setting and Pitch Attitude

Symptom: Student establishes climb or descent but vertical speed is unstable, oscillating between 300-700 fpm, or airspeed varies by 20+ knots.

Cause: Student is making timid power changes (adding or reducing collective in small increments) and waiting to see results before correcting pitch. Or student is making large power changes without simultaneous pitch corrections.

Correction technique: Demonstrate the maneuver using clear callouts: “I’m adding three inches of manifold pressure—now—and simultaneously lowering the nose to maintain 90 knots.” Have the student repeat the maneuver immediately, talking through each action. Emphasize that power and pitch are adjusted together, not sequentially.

Use the analogy of walking up stairs while maintaining eye level—you don’t look at your feet then adjust your neck. You do both simultaneously and naturally.

Instructional note: This is the most common error among transitioning fixed-wing students who are used to power-for-airspeed in cruise flight. Helicopters are power-for-altitude machines. Dedicate extra time to this concept if the student has significant fixed-wing experience.

Error: Improper Correction of Vertical Rate Deviations

Symptom: Student is climbing at 600 fpm instead of 500 fpm. Student reduces collective slightly, and vertical speed decreases to 300 fpm. Student adds collective, overshoots to 700 fpm. Oscillations continue.

Cause: Overcorrecting and not allowing time for the helicopter to stabilize. Also caused by poor scan—student looks at VSI, makes correction, looks away for too long, then checks VSI again to find an opposite error.

Correction technique: Teach “small correction, hold, verify” technique. If 100 fpm off target, make a small collective adjustment (approximately one inch or less manifold pressure), hold that setting for 3-5 seconds, then verify on VSI. If still off, repeat.

Demonstrate the correct scan rate: VSI should be checked every 3-5 seconds during the maneuver, not every 10 seconds.

Use the analogy of adjusting water temperature in a shower—small changes, wait for the response, adjust again if needed. Large corrections create uncomfortable oscillations.

Error: Improper Correction of Airspeed Deviations

Symptom: During a constant rate climb, airspeed decreases from 80 knots to 70 knots. Student pushes forward on cyclic, and airspeed increases to 90 knots. Vertical speed also decreases from 500 fpm to 200 fpm.

Cause: Student made a pitch correction without simultaneously adjusting collective to maintain vertical speed. The cyclic input was also excessive.

Correction technique: Emphasize the coordination required: “When you correct pitch for airspeed, you may need a tiny collective adjustment to maintain vertical speed. Make small cyclic inputs—one inch of movement, not three inches.”

Demonstrate proper technique: “I see 75 knots, I want 80. I’m lowering the nose slightly—watch—and adding just a touch of collective to hold 500 fpm climb. See how the airspeed is coming back smoothly?”

Error: Improper Correction of Heading Deviations

Symptom: In a straight climb or descent, heading drifts 5° right. Student rolls into a 15° bank to correct, altitude and vertical speed deviate significantly.

Cause: Excessive bank angle for the small heading correction. Student fixated on heading indicator and neglected other instruments.

Correction technique: Teach the “degrees of bank for degrees of heading” rule for small corrections: if 5° off heading, use 5° bank to return. “Small heading errors need tiny bank angles. You’re climbing or descending—your primary job is vertical performance. Heading is secondary. Use shallow banks to avoid upsetting the climb or descent.”

Demonstrate: “I’ve drifted 5° right. I’m rolling in just a few degrees of bank—watch the wings on the attitude indicator barely move—and I’m holding my vertical speed and airspeed constant. Now as I approach my heading, I’m rolling out. Total bank was maybe 3-5°.”

Error: Uncoordinated Use of Controls

Symptom: During climbs, the ball is deflected right (not enough left pedal). During descents, ball is deflected left (too much left pedal or not enough right pedal). In turns, ball is deflected to the outside of the turn.

Cause: Student is not scanning the slip-skid indicator, or is unaware of torque changes during power adjustments, or is not adding compensating pedal during turns.

Correction technique: Emphasize that every collective change requires a pedal adjustment. Make this part of the callout for power changes: “I’m adding power for the climb—left pedal. I’m reducing power for the descent—right pedal.”

During turns, teach that any turn requires inside pedal pressure to remain coordinated, slightly more in a climb, slightly less in a descent.

Use the analogy of a car pulling to one side when accelerating or braking—you steer to compensate without thinking about it. In helicopters, you pedal to compensate.

Demonstration technique: Have the student look at the slip-skid indicator while you demonstrate a climb entry without pedal compensation, then with proper pedal. The visual difference in ball position makes the concept concrete.

Error: Improper Trim Control

Symptom: Student is holding constant pedal pressure throughout a climb or descent, or continuously adjusting pedals. In cruise after a climb or descent, helicopter is not trimmed.

Cause: Student doesn’t understand that trim should be adjusted continuously to minimize control pressure, or student believes trim is only for cruise flight.

Correction technique: Emphasize that trim (pedal position for zero pressure) should be adjusted any time control pressure is constant for more than a few seconds. Teach students to verbalize when they feel pressure: “I feel right pedal pressure, so I’m trimming left.”

Demonstrate climbing with proper trim versus improper trim. Show that proper trim allows lighter control inputs and reduces fatigue, critical for single-pilot IFR operations.

In helicopters without friction adjustments or trim systems, teach students to accept that light pressure is normal, but constant medium or heavy pressure indicates an out-of-trim condition that needs power or pedal correction.

Regulatory and Practical Considerations (14 CFR)

Constant rate climbs and descents are required skills for:

• 14 CFR 91.175: IFR approach procedures specify descent rates on final approach segments, often requiring 500-700 fpm in helicopters to remain on glidepath or maintain visual descent angles.

• 14 CFR 91.123: ATC clearances may specify “climb and maintain” or “descend and maintain” with implied expeditious compliance. Constant rate climbs and descents demonstrate compliance without excessive rates that could indicate pilot disorientation or emergency.

• AIM 5-3-7: Published climb gradients for obstacle clearance on departure procedures require specific vertical speed performance. A helicopter must be able to maintain a constant rate climb to ensure obstacle clearance in IMC.

The practical importance for CFII candidates: you must teach students to climb and descend at publishable, sustainable rates that meet ATC expectations and regulatory requirements. A 500 fpm climb or descent is standard, predictable, and comfortable. Teaching students to use 1,000+ fpm rates creates high workload and often leads to altitude busts or loss of control.

Risk Management for Constant Rate Operations

Workload Management in Single-Pilot IFR: Constant rate climbs and descents increase scan workload significantly compared to level flight. The single-pilot helicopter IFR environment demands efficient scan and proper trim to reduce physical workload. Teach students to stabilize first (get the rate and airspeed correct), then handle secondary tasks like frequency changes or approach plate review. Use the principle: fly the helicopter first, navigate second, communicate third.

Power Limitations: In climbs, helicopters may reach maximum power available before achieving target vertical speed, especially at high density altitude or high gross weight. Teach students to recognize insufficient power: if manifold pressure is at maximum continuous and vertical speed is below target, accept the lower rate rather than exceeding power limits. Plan climbs for reduced rates in performance-limited conditions.

Descent Rate and Airspeed Coupling: Excessive descent rates (1,000+ fpm) in helicopters can lead to high rotor RPM or retreating blade stall if combined with high airspeeds. Teach students to monitor rotor RPM during descents and limit descent rates to manufacturer-recommended values, typically 500-700 fpm for IFR operations.

Altitude Awareness During Level-Offs: Altitude busts during level-offs are common student errors. The risk increases when combined with ATC communications or cockpit task saturation. Teach the discipline of calling (or verbalizing) target altitude 1,000 feet prior, 500 feet prior, and at lead point (50 feet prior). This creates altitude awareness through verbal reinforcement.

Partial Panel Spatial Disorientation: On partial panel, students are at increased risk of spatial disorientation during climbs and descents, particularly in turns. The loss of attitude information removes intuitive pitch and bank cues. Teach students to trust instruments completely and avoid “bracketing” maneuvers (repeated reversals) that increase disorientation risk. If confused, return to wings-level, stabilize, then attempt the maneuver again.

Icing Considerations: Helicopters are not certificated for flight into known icing. However, inadvertent icing encounters may require climbs or descents to exit icing conditions. Teach students that any constant rate maneuver in icing increases total lift requirement (due to increased weight), which may be unavailable if ice has degraded rotor efficiency. Exits from icing should prioritize expeditious altitude changes even if normal rates are not maintained.

Instructor Actions

The CFII candidate will:

1. Present the lesson introduction by explaining the importance of constant rate climbs and descents in IFR operations, connecting the skill to published procedures, ATC clearances, and practical scenarios such as departures, approaches, and holds. Clearly state the lesson objectives and completion standards.

2. Teach the power-pitch relationship using whiteboard diagrams, verbal explanations, and analogies that make the concept intuitive. Emphasize that power controls vertical speed and pitch controls airspeed in helicopters. Demonstrate with instrument panel cutout or sim, showing how collective changes affect VSI and how cyclic changes affect airspeed.

3. Demonstrate full panel constant rate climb entry by explaining each step while performing the procedure (chair-flying with instrument panel or in sim): “I’m adding three inches of manifold pressure to achieve 500 feet per minute climb. Simultaneously, I’m lowering the nose slightly with forward cyclic to maintain 80 knots. I’m adding left pedal to counter torque increase and center the ball.” Narrate the scan pattern: “VSI primary for vertical speed, airspeed indicator primary for pitch, attitude indicator for trend.”

4. Demonstrate full panel constant rate descent entry using the same instructional technique—explain while performing. Emphasize power reduction, pitch adjustment for airspeed, and pedal correction for torque change.

5. Demonstrate level-offs from climbs and descents, explaining the 10% lead point rule, simultaneous power and pitch adjustment, and fine-tuning technique. Show how to avoid altitude busts through disciplined scan and timely corrections.

6. Demonstrate constant rate climbing and descending turns (full panel), explaining the additional collective required to maintain vertical speed in the turn, bank angle limitations (standard rate), and increased scan workload. Emphasize coordination of all controls.

7. Explain and demonstrate partial panel procedures for constant rate climbs, descents, and turns. Cover instrument substitutions (turn coordinator for bank, airspeed/VSI for pitch), increased scan workload, and methods to reduce spatial disorientation risk.

8. Present each common student error identified in the PTS knowledge items by describing symptoms, explaining causes, and demonstrating correction techniques. Use scenario-based examples: “Your student is climbing at 600 fpm instead of 500. What’s your first instructional step?” Answer by demonstrating proper correction and explaining instructional technique.

9. Teach risk management considerations specific to helicopters: single-pilot IFR workload, power limitations, descent rate/airspeed coupling, altitude awareness techniques, partial panel disorientation risks, and icing considerations. Use decision-making scenarios to illustrate practical applications.

10. Simulate teaching a student by delivering a 10-minute instructional segment on constant rate climbs to the evaluator (who role-plays as an instrument student). Use clear explanations, demonstrations, and check student understanding through questioning. When the evaluator (as student) demonstrates common errors, diagnose the error and provide effective correction using appropriate teaching techniques.

11. Analyze and correct simulated student errors during the teaching demonstration. When the evaluator performs incorrect techniques (e.g., overcorrecting vertical speed, uncoordinated flight, improper trim), the candidate must identify the error, explain the cause, demonstrate the correct technique, and have the “student” repeat the maneuver correctly.

12. Answer evaluator questions about instructional techniques, error correction, risk management, and regulatory requirements throughout the lesson presentation. Demonstrate depth of knowledge and ability to adapt explanations to student needs.

4. Evaluate the candidate’s error analysis by noting whether the candidate correctly identifies each error, explains the cause accurately, and demonstrates effective correction technique.

5. Ask scenario-based questions to assess candidate’s depth of knowledge, such as: “Your student is struggling to maintain airspeed during climbs on partial panel. What’s your instructional approach?” or “How would you teach a student to recognize insufficient power during a climb at high density altitude?”

6. Assess regulatory knowledge by asking questions about 14 CFR requirements related to constant rate operations, such as climb gradient requirements or IFR approach descent rate considerations.

7. Evaluate risk management understanding by presenting scenarios such as: “Your student is hand-flying a constant rate descent in turbulence at night. What risks should you brief?” or “What would you emphasize about constant rate operations in a helicopter not certificated for flight into known icing?”

8. Provide feedback during the debrief on instructional effectiveness, areas of strength, and areas needing improvement.
