Abstract
A system and a method for varying a maximum roll rate command for ensuring sufficient directional control during an engine-out rolling maneuver of a multi-engine aircraft. For a multi-engine airplane with a roll rate command flight control system, the primary flight control computer is used to vary the maximum commandable roll rate to preserve the desired control margins during roll maneuvers where the rudder is fully deflected to control a thrust asymmetry. When the engine-out yawing moment exceeds a specified value, the system sets a reduced limit on the amount of roll rate the pilot can command.
