Document Type and Number:
Japanese Patent JP2850038
Kind Code:
B2
Abstract:
Control apparatus for an aircraft area navigation system provides transitioning from an inbound leg (12) to an outbound leg (13) of a lateral navigation waypoint (10) with a fixed curved transition path (15) with or along the outer limit of the protected airspace width or PAW. The present invention determines in conjunction with the aircraft altitude and the angle of the course change a maximum distance that the aircraft will deviate from either the inbound or outbound leg. This distance is sometimes called the maximum cross track error or MXTK. The maximum cross track error information in conjunction with the course change angle is used to generate a turn radius for a fixed curved transition path to be followed by the aircraft independent of ground speed. The turn radius information together with the aircraft ground speed information is used to generate a bank angle command signal. The bank angle bias command is calculated to vary the bank angle of the aircraft so as to keep the aircraft on the fixed curved path throughout the transition from inbound to outbound waypoint legs.
