<p>PURPOSE: To facilitate maneuver by providing a means for outputting a first control signal when the bob-up maneuver for ascending to the second altitude upper than the first altitude as the present position is performed, while, outputting a second control signal when bob-down maneuver for descending form the second altitude to the first altitude is performed. CONSTITUTION: In a collective pitch lever 10 for controlling the flight altitude of a helicopter according to the direction operated by a pilot, a switch 11 for starting or controlling the bob-up and bob-down maneuvers is provided. The switch 11 has a structure of a so-called three-position switch. When the switch 11 is pushed in one direction, a first control signal for the ascent flight for moving a helicopter from the first altitude as the present position to the higher altitude desired by the pilot is output, while, when the switch is pushed in the other direction, a second control signal for the descent flight for descending from the present position to the attitude before the ascent flight is performed is output. The first altitude is recorded in response to the first control signal, and the flight maneuver is performed by a control computer on the basis of a ascent or descent command signal.</p> |
