Abstract:
1. A method for operating an aircraft, the method comprising: determining an output from a roll in logic based upon an OR gate processing outputs from dual AND gates processing logic unit outputs based upon inputs comprising: a roll rate, and a limited roll angle, for the aircraft; selecting, using the output from the roll in logic, at least one of: a roll in gain and a roll out gain; deriving a current lift for the aircraft, using a pitch angle adjustment system comprising at least one of: the roll in gain, and the roll out gain; responsive to a turning of the aircraft when holding an altitude, identifying, using the current lift for the aircraft, an identified adjustment to a pitch angle of the aircraft needed to substantially maintain the altitude of the aircraft during the turning of the aircraft; and performing the turning of the aircraft using the identified adjustment.
