In the event of unforeseen aircraft faults, safe and timely recovery may depend on multiple layers of decision-making. This paper applies retrospective cost adaptive control (RCAC) to the inner control loop of an aircraft’s safety-management system and investigates the ability to follow sequences of trim commands given by higher level flight planners. We first show that trim conditions can be realized by commanding constant airspeed, flight path angle, and turn rate, and then investigate the ability of RCAC to follow possibly conflicting trim commands with minimal modeling of the static flight envelope.
