Attitude instrument flying in helicopters is essentially visual flying with the flight instruments substituted for the various reference points on the helicopter and the natural horizon. Control changes, required to…
Advances in technology have brought about changes in the instrumentation found in all types of aircraft, including helicopters. Electronic displays commonly referred to as “glass cockpits” are becoming more common.…
The procedures and techniques described here should be modified as necessary to conform to those set forth in the operating instructions for the particular helicopter being flown. During training, instrument…
Unusual Attitudes Any maneuver not required for normal helicopter instrument flight is an unusual attitude and may be caused by any one or combination of factors, such as turbulence, disorientation,…
Turns made by reference to the flight instruments should be made at a precise rate. Turns described in this post are those not exceeding a standard rate of 3° per…
Straight Climbs (Constant Airspeed and Constant Rate) For any power setting and load condition, there is only one airspeed that gives the most efficient rate of climb. To determine this,…
Straight-and-level unaccelerated flight consists of maintaining the desired altitude, heading, airspeed, and pedal trim. Pitch Control The pitch attitude of a helicopter is the angular relation of its longitudinal axis…
To achieve smooth, positive control of the helicopter during instrument flight, three fundamental skills must be developed. They are instrument cross-check, instrument interpretation, and aircraft control. Instrument Cross-Check Cross-checking, sometimes…
