List of aircraft upset factors

The U.S. FAA lists factors of aircraft upset in the Airplane Upset Recovery Training Aid as follows:


 * Turbulence causes:
 * Clear air turbulence
 * Mountain wave turbulence
 * Windshear
 * Thunderstorms
 * Microbursts
 * Wake turbulence
 * Aircraft icing
 * Systems anomalies:
 * Flight instruments
 * Autoflight systems
 * Flight control and other anomalies
 * Pilot-Induced
 * Instrument cross-check
 * Adjusting attitude and power
 * Inattention
 * Distraction from primary cockpit duties
 * Vertigo or spatial disorientation
 * Pilot incapacitation
 * Improper use of airplane automation
 * Pilot techniques
 * Pilot induced oscillation avoidance and recovery
 * Combination causes:
 * Swept-wing airplane fundamentals for pilots
 * Flight dynamics
 * Energy states
 * Load factor (flight mechanics)
 * Aerodynamic flight envelope
 * Aerodynamic causes:
 * Angle of attack and stall
 * Camber
 * Control surface fundamentals
 * Spoiler-type devices
 * Trim
 * Lateral and directional aerodynamic considerations
 * Angle of sideslip
 * Wing dihedral effects
 * Pilot-commanded sideslip
 * Crossover speed
 * Static stability
 * Maneuvering in pitch
 * Mechanics of turning flight
 * Lateral and directional maneuvering
 * Flight at extremely low airspeeds
 * High-altitude factors
 * Stall
 * icing
 * Automation during high-altitude flight
 * Primary flight display airspeed indications
 * Human factors and high altitude upsets
 * Additional considerations:
 * Multi-engine flame out
 * Core lock
 * Engine rollback
 * Flight at extremely high speeds
 * Defensive, aggressive maneuvers
 * Situation awareness
 * Startle factor
 * Negative G-force
 * Use of full control inputs
 * Counter-intuitive factors
 * Previous training in non-similar airplanes
 * Engine performance in upset situation
 * Post-upset conditions
