CH.VIII.M — Recovery from Unusual Flight Attitudes

What does ACS code CH.VIII.M cover?

ACS Code CH.VIII.M covers "Recovery from Unusual Flight Attitudes" under Area of Operation VIII (Emergency Operations) for the FAA Commercial Pilot Helicopter certificate (FAA-S-ACS-16). Candidates are tested on knowledge elements and risk management factors defined in 14 CFR regulations and FAA handbooks (PHAK / AFH).

Airman Certification Standards Elements

Knowledge Elements

• CH.VIII.M.K1: Prevention of unusual attitudes, including flight causal, physiological, and environmental factors, and system and equipment failures.
• CH.VIII.M.K2: Procedures for recovery from unusual attitudes in flight.
• CH.VIII.M.K3: Procedures available to safely regain visual meteorological conditions (VMC) after flight into inadvertent instrument meteorological conditions or unintended instrument meteorological conditions (IIMC)/(UIMC).
• CH.VIII.M.K4: Appropriate use of automation, if applicable.

Risk Management Elements

• CH.VIII.M.R1: 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).
• CH.VIII.M.R2: Assessment of the unusual attitude.
• CH.VIII.M.R3: Control input errors, inducing undesired aircraft attitudes.
• CH.VIII.M.R4: Collision hazards.
• CH.VIII.M.R5: Distractions, task prioritization, loss of situational awareness, or disorientation.
• CH.VIII.M.R6: Interpreting flight instruments.
• CH.VIII.M.R7: Control application solely by reference to instruments.
• CH.VIII.M.R8: Operating envelope considerations.

How do I study CH.VIII.M?

1. Read each element for CH.VIII.M in FAA-S-ACS-16 and note any you cannot explain in your own words.
2. Study each one in the FAA source it points to: the handbook chapter, the 14 CFR section or the AIM paragraph.
3. Practice with questions tagged CH.VIII.M, and read the explanation for every miss.
4. Retest, then review the ACS codes you still miss on your practice test report.
