The student will comply with all ATC clearances and restrictions, establish appropriate descent rates for helicopter operations, and maintain airspeed within ±10 knots, heading within ±10°, altitude within ±100 feet, and accurately track courses, radials, and bearings in accordance with FAA-S-ACS-ATP Task AT.VI.A.

Content

En Route and Arrival Chart Knowledge

Chart Selection and Currency

• 14 CFR 91.103 requires familiarity with all available information for IFR flights
• En Route Low Altitude Charts (L-charts): valid from surface to but not including 18,000 feet MSL
• En Route High Altitude Charts (H-charts): valid 18,000 feet MSL through FL450
• Helicopter-specific considerations: most turbine helicopters operate primarily in low altitude structure below 10,000 feet for efficiency
• Chart currency: verify current edition and effective dates; expired charts are prohibited for IFR operations
• NAVAIDs: depicted with frequencies, identifiers, morse code, service volumes, and restrictions
• MEAs, MOCAs, MRAs, MCAs: minimum altitudes provide obstacle clearance and navigation signal reception
• Helicopter operators must verify obstacle clearance when flying below MEA (permitted under certain conditions per AIM but requires pilot responsibility for terrain clearance)

STAR Knowledge and Application

• Standard Terminal Arrival Routes (STARs) published to simplify clearance delivery and reduce frequency congestion in busy terminal areas
• STARs transition aircraft from en route structure to the initial approach fix or feeder route
• “Pilot Nav” STARs: pilot responsible for navigation along depicted route
• “Vector” STARs: expect radar vectors in lieu of published routing at some point
• Speed restrictions: depicted in knots IAS; helicopter pilots must consider true airspeed differential at altitude affects wind correction and descent planning
• Altitude restrictions: “expect” altitudes are planning information only; mandatory, minimum, maximum, and at-or-above/at-or-below restrictions must be complied with
• ATC may amend altitude and speed restrictions; comply promptly and read back all changes
• Filing STARs: include full STAR name with transition in flight plan; be prepared to fly as published or accept amendments
• STAR refusal: include “NO STAR” in remarks section of flight plan; ATC will issue full routing

Instrument Approach Procedure Charts and Arrival Integration

• IAP charts provide final navigation guidance from initial approach fix to runway or missed approach point
• Feeder routes connect en route structure or arrival routes to initial approach fixes
• Chart components: plan view, profile view, minimums section, airport diagram, notes
• Helicopter-specific approaches: some IAPs include helicopter-only procedures with reduced visibility minimums
• Helicopter point-in-space approaches: terminate at MAP with no runway in sight; require VFR segment to landing area
• Review approach plate before descent on arrival: verify frequencies, courses, minimums, missed approach procedure
• Brief the approach: verbalize key elements enhances situational awareness and CRM even in single-pilot operations

Pilot and Controller Responsibilities During Arrivals

Pilot Responsibilities:

• Maintain aircraft control and navigation precision throughout arrival
• Comply with all altitude, airspeed, and routing restrictions
• Advise ATC immediately of inability to comply with clearance
• Maintain published speeds unless otherwise cleared (do not slow below speeds causing flight control difficulties)
• Cross all crossing restrictions on time; advise ATC if unable
• Monitor position using all available navigation sources
• Execute missed approach if unable to comply with arrival or approach requirements
• Maintain communication and advise ATC of equipment malfunctions

Controller Responsibilities:

• Issue clearances that ensure separation from other aircraft and terrain
• Provide vectors or route amendments as traffic requires
• Issue speed adjustments as necessary for sequencing
• Provide weather information, NOTAMs, and airport advisories
• Clear aircraft for approach when appropriate or provide vectors

Two-Way Communications Failure Procedures

• 14 CFR 91.185: governs pilot actions during communications failure in IFR conditions
• Transponder: squawk 7600 immediately
• Route to fly: use acronym “AVE-F” — Assigned, Vectored, Expected, Filed
  • Assigned: last assigned route in last ATC clearance received
  • Vectored: proceed direct to fix, route, or airway specified in vector clearance
  • Expected: route ATC advised to expect in further clearance
  • Filed: route filed in flight plan
• Altitude to fly: use acronym “MEA” — Minimum, Expected, Assigned (highest of three)
  • Minimum: minimum altitude for IFR operations (MEA, MOCA, or assigned altitude)
  • Expected: altitude ATC advised to expect in further clearance
  • Assigned: last assigned altitude
• Leave clearance limit: if clearance limit is IAF, begin descent and approach as close as possible to EFC time or estimated arrival time if no EFC received
• Complete approach and land as soon as practicable
• Helicopters should consider fuel state and nearest suitable airport when selecting course of action
• VFR conditions: if VFR conditions encountered, consider exiting IFR and proceeding VFR under 14 CFR 91.185(a)

Risk Management and Professional Operations

Timely Compliance with ATC Instructions

• Professional IFR operations demand immediate acknowledgment and compliance with clearances
• Read back all altitude assignments, heading assignments, speed restrictions, approach clearances, frequency changes, and transponder codes
• Query ATC immediately if clearance is unclear, incomplete, or creates safety concern
• In helicopters, performance limitations may require deviation: “Unable” is appropriate phraseology; provide reason and request alternative
• At ATP level, anticipation is key: recognize clearances before they are issued based on flow, STAR depiction, and traffic
• Pre-plan transitions: know next frequency, next fix, next restriction before reaching current checkpoint

Airspeed Management and Restrictions

• 14 CFR 91.117: 250 knots below 10,000 feet MSL (rarely limiting factor for helicopters)
• STAR-depicted speeds must be adhered to unless amended by ATC
• Helicopter-specific consideration: turbine helicopters often cruise 120-140 KIAS; ATC may request speeds slower or faster than optimal
• Never slow below Vy in IMC during arrival to maintain adequate margin above VRS and settling-with-power conditions
• Speed adjustments in descent: anticipate power requirements; avoid high rates of descent at slow speeds
• Coordinate with ATC if speed restriction creates safety concern (e.g., icing conditions requiring higher speed for deice system effectiveness)
• Maintain speed discipline: ATP standards require ±10 knots throughout arrival and approach phases

Descent Rate Management for Helicopter Operations

• Helicopter descent planning differs from fixed-wing: no beta range or speedbrakes; descent controlled by power reduction and airspeed management
• Conservative descent rates prevent high-power go-arounds from low-speed, high-descent-rate conditions
• Plan descents to avoid continuous descent below transitioned airspeed at high descent rates (settling-with-power risk)
• Turbine helicopters: monitor TOT/TGT during descent; rapid power increases during level-off can exceed limits
• Use “2% rule” for helicopters: approximately 200 FPM per 10 knots of desired speed reduction provides smooth deceleration
• Consider density altitude: descent performance at high elevation destinations requires earlier planning
• Brief descent parameters: target altitude, level-off altitude, vertical speed, airspeed throughout descent

Professional CRM and Single-Pilot Resource Management

• At ATP level, mental workload management is critical even without crew
• Use systematic flows: WIRE check (Weather, Instruments, Radios, Equipment) before top of descent
• Verbalize intentions during single-pilot IFR operations: talking through clearances and procedures enhances situational awareness
• Prepare approach chart in advance: have plate accessible, frequencies pre-loaded, minimums identified before top of descent
• Automate when appropriate: use autopilot to reduce workload during high-task arrival phases if available
• Maintain positive aircraft control: trimming aircraft for hands-off flight reduces fatigue in busy terminal environments
• Monitor fuel state: STARs and arrivals can add distance and time; verify fuel sufficient for approach, missed approach, and alternate

Instructor Actions

1. Begin the lesson by reviewing the student’s prior experience with instrument arrivals, STARs, and terminal area operations. Ask: “Walk me through the last time you flew a STAR—what were the biggest challenges in workload and planning?” This establishes baseline competency and identifies weak areas.

2. Present current En Route Low Altitude Chart covering local training area. Point out key features: MEAs, MOCAs, airways, NAVAIDs, and airspace boundaries. State: “At the ATP level, chart reading must be instant and automatic—you should be able to glance at a chart and extract altitude restrictions, courses, and navaid information within seconds.”

3. Explain the difference between En Route Low and High Altitude Charts. Emphasize: “Most helicopter IFR operations occur on low altitude charts below 10,000 feet. You need to be comfortable with both, but your day-to-day flying will live in the low altitude environment.”

4. Display a current STAR chart for a nearby Class B or Class C airport. Walk through each component: title, transition routes, altitude restrictions (mandatory/at-or-above/at-or-below/expect), speed restrictions, notes, and lost communications procedures. State: “Every box, every number, every note on this chart means something—there’s no fluff on instrument charts.”

5. Teach the difference between “pilot nav” and “vector” STARs. Show examples of each. Explain: “On pilot nav STARs, you fly the depicted route yourself. On vector STARs, you’ll receive radar vectors at some point. Know which you’re flying before you accept the clearance.”

6. Demonstrate STAR briefing technique using the five-point method: (1) Transition and routing, (2) Altitude restrictions, (3) Speed restrictions, (4) Expected approach, (5) Missed approach considerations. State: “A complete STAR brief takes 60 seconds and prevents 99% of arrival errors.”

7. Explain altitude and speed restriction symbology. Draw examples on whiteboard: mandatory (underline and overline), at-or-above (overline only), at-or-below (underline only), expect (non-underlined in parentheses). Reinforce: “Expect altitudes are planning information—you cannot descend to them without ATC clearance.”

8. Address helicopter-specific considerations during STARs: power management in descent, descent rate limitations to avoid settling-with-power, fuel consumption during extended routings. State: “Unlike fixed-wing aircraft, we don’t have speed brakes. Plan your descents conservatively and start early.”

9. Teach pilot and controller responsibilities. List pilot responsibilities on whiteboard: aircraft control, navigation, compliance with restrictions, timely communication, position awareness. List controller responsibilities: separation, clearances, weather information, traffic advisories. Emphasize: “You own aircraft control and navigation. ATC owns separation and sequencing. Know where the handoff is.”

10. Present 14 CFR 91.185 two-way communications failure procedures. Teach the “AVE-F” acronym for route (Assigned, Vectored, Expected, Filed) and “MEA” acronym for altitude (Minimum, Expected, Assigned—fly the highest). Walk through multiple scenario examples.

11. Explain communications failure during arrival: “If you lose comms while on a STAR, squawk 7600, continue on last assigned route and altitude, expect vectors to the approach at the clearance limit or IAF. If you’re given an expect further clearance time, start your approach at that time. No EFC? Use your estimated arrival time.”

12. Discuss the practical decision-making during communications failure: “14 CFR 91.185(a) says if you encounter VFR conditions, you can leave IFR and proceed VFR. In a helicopter, if you lose comms and break out VFR over an uncontrolled field, landing and calling ATC by phone is often the safest choice.”

13. Address the risk management item of timely compliance. Demonstrate proper readback technique: “Read back all altitude assignments, headings, speed restrictions, approach clearances, and frequencies. If you don’t understand or can’t comply, say ‘unable’ immediately with a reason. Don’t accept a clearance you can’t fly.”

14. Teach speed management during arrivals. Explain: “Most turbine helicopters cruise 120-140 knots. ATC may ask for faster or slower speeds. Know your aircraft limits: never slow below Vy in IMC, and don’t exceed VNE in descent. If ATC issues a speed restriction you can’t meet safely, say ‘unable due to aircraft limitations’ and request an alternative.”

15. Demonstrate descent planning for helicopters using the “2% rule”: approximately 200 FPM for every 10 knots of desired speed reduction. Show calculation example: “If you’re at 140 knots and need to slow to 100 knots, that’s 40 knots or about 800 FPM descent while decelerating. Start your descent early.”

16. Explain the hazard of high descent rates at slow speeds in helicopters: increased power-on descent risk, settling-with-power, and vortex ring state. State: “If ATC asks for a high rate of descent, ensure you maintain adequate forward airspeed. If you need to slow down, reduce your descent rate first.”

17. Discuss single-pilot resource management during arrivals: “Set up radios in advance. Brief the STAR and approach before top of descent. Use flows and checklists. Verbalize your actions even when alone—it keeps you ahead of the aircraft.”

18. Present a realistic arrival scenario: “You’re 60 miles north of the airport at 8,000 feet on an airway. You’ve just been cleared for the [local STAR] arrival, expect the ILS Runway [XX] approach. Walk me through how you prepare for this arrival right now.”

19. Review the ATP completion standards explicitly: “During the practical test, you must maintain airspeed within ±10 knots, heading within ±10°, altitude within ±100 feet, and accurately track all courses and radials. These are tighter than commercial standards—practice precision now.”

20. Demonstrate using current navigation publications: show electronic database currency check on EFB, demonstrate accessing current STAR from ForeFlight or Garmin Pilot, show paper backup chart organization. State: “Always verify your database is current. Expired data equals illegal IFR operation under 14 CFR 91.103.”

21. Set up ground practice exercise: provide student with printed STAR chart and simulate ATC clearance: “Helicopter [N-Number], cleared to [destination] via [STAR]. Descend and maintain [altitude], expect [approach].” Have student read back and brief the arrival.

22. Conduct pre-flight planning phase: student files IFR flight plan including STAR, obtains weather briefing, reviews NOTAMs, identifies frequencies, and completes arrival briefing card. Monitor and provide feedback on planning efficiency and thoroughness.

23. During flight (or FTD session), simulate receiving STAR clearance from ATC. Evaluate student’s readback accuracy, chart identification speed, and frequency selection. Prompt: “You have 30 seconds from receipt of clearance to have the chart up and ready—ATC expects you to comply immediately.”

24. Observe student’s execution of arrival procedure: verify proper course interception, altitude restriction compliance, speed management, and communication. Provide real-time coaching: “You’re approaching a crossing restriction—verify your altitude now.”

25. Introduce scenario variation: simulate ATC amending an altitude restriction or issuing speed adjustment mid-arrival. Evaluate student’s readback and execution. Prompt if needed: “How does this speed change affect your descent planning?”

26. During flight phase, simulate navigation facility failure (e.g., GPS outage). Ask: “Your GPS just went offline. What navigation source backs you up for this arrival?” Verify student can transition to VOR/DME navigation without altitude or course deviations.

27. Conduct communications failure simulation: direct student to simulate lost communications, observe squawk change to 7600, and verbalize decision-making using AVE-F and MEA acronyms. State: “Talk me through every decision you’re making—I need to hear your thought process.”

28. Evaluate student’s ability to intercept and track courses, radials, and bearings during arrival. Observe CDI/HSI/GPS course guidance management. Provide feedback on bracketing technique and wind correction: “You’re chasing the needle—establish a 5-degree correction and hold it.”

29. Monitor altitude and airspeed adherence throughout arrival. Call out deviations immediately: “You’re 120 feet high at the crossing restriction—that’s outside ATP standards. What happened?” Debrief error chain and corrective action.

30. Evaluate student’s checklist discipline: arrival checklist, approach briefing, descent checklist. Verify proper flow and no missed items. Reinforce: “At ATP level, checklist discipline is non-negotiable. Every item, every time.”

31. Transition arrival to approach phase: observe student’s coordination between arrival completion and approach commencement. Verify proper sequencing: approach clearance received, approach chart briefed, final approach course intercepted.

32. Conduct missed approach from arrival: simulate ATC instruction to break off arrival and execute published missed approach. Evaluate immediate compliance, proper power application, pitch attitude, course guidance, and communication.

33. Debrief flight in detail: review each restriction and tolerance, discuss any deviations, analyze workload management, and reinforce positive performance. Ask: “What was your highest workload moment during that arrival? How would you reduce it next time?”

34. Assign follow-up practice: direct student to chair-fly two additional STARs from different airports, complete arrival briefing cards for each, and prepare for oral questioning on communications failure procedures during next lesson.
