Instrument Rating (Helicopter) Recovery from Unusual Flight Attitudes Lesson Plan

Instrument Rating (Helicopter) • ACS Area IV, Task B

The Instrument Rating (Helicopter) Recovery from Unusual Flight Attitudes Lesson Plan covers the knowledge, risk management, and flight skills required by FAA-S-ACS-14.

Introduction

  • Attention Getter: Present an IFR helicopter operation in which small errors, changing weather, automation, or workload can rapidly erode terrain, obstacle, power, or control margins.
  • Objective: To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with recovering from unusual flight attitudes solely by reference to instruments.

Instructor Actions

  • Teach the task progressively in realistic helicopter IFR context and preserve aircraft control, obstacle clearance, power margin, and workload capacity.
  • Teach and assess the following knowledge elements:
    • Prevention of unusual attitudes, including flight causal, physiological, and environmental factors, and system and equipment failures. (IH.IV.B.K1)

    • Appropriate use of automation, if applicable. (IH.IV.B.K4)
  • Use realistic helicopter IFR scenarios to teach and assess the following risk-management elements:
    • Situations that could lead to loss of control in-flight (LOC-I) or unusual attitudes in-flight (e.g., stress, task saturation, inadequate instrument scan distractions, and spatial disorientation). (IH.IV.B.R1)
    • Assessment of the unusual attitude. (IH.IV.B.R2)

    • Operating envelope considerations. (IH.IV.B.R9)
  • Demonstrate, coach, and assess the following skills:
    • Use proper instrument cross-check and interpretation to identify an unusual attitude (including both nose-high and nose-low), and apply the appropriate pitch, bank, and power corrections, in the correct sequence, to return to a stabilized level flight attitude. (IH.IV.B.S1)
    • Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate. (IH.IV.B.S2)
  • Syllabus Objective Coverage:
    • Manage fatigue, distractions and disorientation before control deteriorates.
      • Interrupt nonessential troubleshooting or task fixation when workload threatens aircraft control.
    • Recognize an unusual attitude using corroborated indications.
      • Cross-check independent instruments and trends before applying unusual-attitude recovery inputs.
    • Select the appropriate recovery while respecting the operating envelope.
      • Recognize a nose-high unusual attitude and apply the manufacturer-recommended helicopter recovery sequence.
      • Recognize a nose-low unusual attitude and apply the manufacturer-recommended helicopter recovery sequence.

      • Establish a stable helicopter attitude, heading, airspeed, and power using reliable instrument references after unexpected IMC entry.
    • Choose a supported route toward safer conditions without blind descent.
      • Select and execute an aircraft-specific escape or recovery plan after inadvertent IMC while maintaining terrain and obstacle clearance.
    • Use suitable automation with verified modes and reliable inputs.
      • Verify active automation modes, commanded response, and source validity; disconnect automation when it produces unexpected or unsafe behavior.

      • Interrupt nonessential troubleshooting or task fixation when workload threatens aircraft control.
    • Recognize an unusual attitude using corroborated indications.
      • Cross-check independent instruments and trends before applying unusual-attitude recovery inputs.
    • Identify, assess, and select effective controls for risks associated with control input errors inducing undesired aircraft attitudes, e.g. low G rotor.
    • Identify, assess, and select effective controls for risks associated with pilot responses that lead to mast bumping in a low G condition, if applicable.
    • Identify traffic, terrain, obstacle, and other collision hazards before and during unusual-attitude recognition and recovery.
    • Select and maintain a recovery path that preserves traffic, terrain, and obstacle clearance while restoring controlled flight.
    • Identify distraction, fixation, task-prioritization, situational-awareness, and disorientation hazards during unusual-attitude recognition and recovery.
    • Prioritize reliable instrument cross-check, aircraft control, and a safe flightpath over nonessential communication or troubleshooting during unusual-attitude recovery.
    • Interrupt checklist or troubleshooting fixation to preserve aircraft control and a safe flightpath.
    • Defer nonessential radio details while preserving aircraft control and terrain clearance.
    • Integrate aircraft control, threat response, navigation, communications, and landing priorities during an instrument emergency.
    • Recognize an unusual attitude using corroborated indications.
      • Cross-check independent instruments and trends before applying unusual-attitude recovery inputs.
    • Select the appropriate recovery while respecting the operating envelope.
      • Recognize a nose-high unusual attitude and apply the manufacturer-recommended helicopter recovery sequence.
      • Recognize a nose-low unusual attitude and apply the manufacturer-recommended helicopter recovery sequence.
    • Select the appropriate recovery while respecting the operating envelope.
      • Recognize a nose-high unusual attitude and apply the manufacturer-recommended helicopter recovery sequence.
      • Recognize a nose-low unusual attitude and apply the manufacturer-recommended helicopter recovery sequence.
    • Use proper instrument cross-check and interpretation to identify an unusual attitude (including both nose-high and nose-low), and apply the appropriate pitch, bank, and power corrections, in the correct sequence, to return to a stabilized level flight attitude.
    • Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
