Ex 15. Recognition of unusual attitudes:
Prevention of dangerous conditions
.

Aim:

To recognise and recover from unusual attitudes in order to prevent the aircraft entering dangerous conditions.

Note: This exercise must not be practised solo by the student

Airmanship:

  • HASELL checks

Aircraft limits:

 

  • (Refer to POH) Definition of Flight Envelope; Vne, Va, Vno, Vfe, Max bank, Max pitch, Max +ve and -ve “G”
  • Dangers associated with exceeding aircraft limits
  • Weight shift aircraft – the Tumble
  • Need for inspection following flight outside envelope.

Aircraft Stability Characteristics:

  • Weightshift – need to maintain +ve G
  • Pitch-positive tendencies
  • Roll Inertia.

Possible causes of unusual attitudes:

  • From inadvertent mishandling of controls at high speeds
  • From inadvertent mishandling of controls in stall recovery in various configurations
  • From inadvertent mishandling of controls in a steep turn
  • From inadvertent mishandling controls following hitting own wake turbulence in a steep turn
  • Severe meteorological turbulence.
  • Loss of control following spatial disorientation.
  • Deliberate manoeuvres outside the pilot’s ability.

Recognition of Unusual Attitudes:

  • Attitude in relation to horizon.
  • Speed and Energy State.
  • Instrument lag

Recovery Techniques from:

  • Nose high, wings level
  • Nose high, wings banked
  • Nose low, wings level,
  • Nose low, wings banked

Management of Controls during Simulation/Practice

  • Need for smooth positive inputs, control of “G”
  • Instructor to set up unusual attitude
  • Handover/passing of control

Motion Sickness

  • Exercise to be terminated at onset.

*********************************************************************

Standard required at end of phase 4

Ability to control aircraft safely at steep angles of bank, with correctly coordinated roll, pitch, and power. Ability to avoid the spiral dive and understand wake turbulence. Ability to use sideslipping usefully and safely. An understanding of unusual attitudes and dangerous conditions. The ability to recognise the onset of unusual attitudes and take instinctive recovery action to prevent a dangerous condition developing.
