STRAIGHT AND LEVEL FLIGHT

Flight training really begins with instruction in the techniques of straight and level flight. The objectives are to point the helicopter in a particular direction, maintain that direction and fly at a predetermined altitude.

The helicopter pilot maintains direction and altitude by controlling the pitch and bank with reference to the natural horizon. This is called attitude flying. During training, the pilot learns that there is a fixed attitude and a fixed angle of bank, in relation to the natural horizon, for each flight condition.

The pilot must be aware of the differences between visual flying and instrument flying.

Visual flying simply means that the natural horizon is used as the main reference.

Instrument flying is performed when the pilot refers to instruments for attitude reference.

The emphasis during basic training will be on visual flying.

In straight and level cruising flight, the helicopter will be slightly nose-down and laterally level in relation to the horizon. To maintain this configuration, it is necessary to establish the relationship of the helicopter to the natural horizon. One of the best ways a helicopter pilot can accomplish this is by using the distance between the horizon and the main rotor tip-path plane as a reference. For any given airspeed, the distance will remain the same as long as the pilot sits in the same position in the same type of helicopter.
