Recovery from Unusual Flight Attitudes
Knowledge
Procedures for recovery from unusual attitudes in flight.
Prevention of unusual attitudes, including flight causal, physiological, and environmental factors, and system and equipment failures.
Procedures available to safely regain visual meteorological conditions (VMC) after flight into inadvertent instrument meteorological conditions or unintended instrument meteorological conditions (IIMC)/(UIMC).
Appropriate use of automation, if applicable. 11
Risk Management
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).
Operating envelope considerations.
Interpreting flight instruments.
Assessment of the unusual attitude.
Control input errors, inducing undesired aircraft attitudes.
Control application solely by reference to instruments.
Collision hazards.
Distractions, task prioritization, loss of situational awareness, or disorientation.
Skill
Use proper instrument cross-check and interpretation to identify an unusual attitude (including both nose-high and nose-low) in flight, and apply the appropriate flight control, power input, and aircraft configuration 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. 12
