Helicopter Instrument Unusual Attitudes[PDF]
Any manoeuvre not required for normal helicopter instrument flying is an unusual attitude and may be caused by any one or a combination of factors, such as turbulence, disorientation, instrument failure, confusion, preoccupation with flight deck duties, carelessness in cross-checking, errors in instrument interpretation, or lack of proficiency in aircraft control.
To recover from an unusual attitude, a pilot should correct bank-and-pitch attitude and adjust power as necessary.
If the helicopter is in a climbing or descending turn, adjust bank, pitch and power.
- The bank attitude should be corrected by referring to the turn-and-slip indicator and attitude indicator
- Pitch attitude should be corrected by reference to the altimeter, airspeed indicator, VSI and attitude indicator.
- Adjust power by referring to the airspeed indicator and manifold pressure/torque
Aircraft is in a banked left and pitched down attitude. VSI shows a high rate of descent and turn and slip indicator confirms the situation.
1- Adjust Bank Attitude
First action is applying enough right cyclic to correct bank attitude and enough left rudder to ensure trimmed flight.
2- Adjust Pitch Attitude
Second action is applying enough back cyclic to correct pitch down attitude.
3- Adjust Power
Last action is to adjust power to ensure a level flight at desired airspeed and altitude.
4- Straight and Level Flight
Now the aircraft is in Straight and Level Flight.
