ROLL ATTITUDE-DEPENDENT ROLL RATE LIMIT

摘要

Systems and methods are provided for a roll attitude dependent roll rate limit that may limit an aircraft to a lower roll rate limit under normal flight conditions. The systems and methods may detect situations where a higher roll rate limit may be desirable and allow the aircraft to exceed the lower roll rate limit, to either a higher roll rate limit or a roll rate between the lower and higher roll rate limit.

1. A system comprising:
at least one bank angle sensor configured to output bank angle data; at least one roll rate sensor configured to output roll rate data; and a controller communicatively connected to the at least one bank angle sensor and the at least one roll rate sensor and configured to:
determine a vehicle dynamic characteristic with, at least, the bank angle data;determine a current roll rate of the vehicle from, at least, the roll rate data;determine if the vehicle dynamic characteristic is within a first dynamic range and then limit allowable roll rate to a first roll rate limit;determine if the vehicle dynamic characteristic is within a second dynamic range and then limit allowable roll rate to a second roll rate limit; anddetermine if the vehicle dynamic characteristic is within a transition dynamic range between the first dynamic range and the second dynamic range, determine a calculated roll rate limit, and then limit allowable roll rate to the calculated roll rate limit.
