Abstract

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.
