An aircraft, the aircraft including a whole-aircraft ballistic parachute that is coupled to the aircraft. The aircraft determines if a pre-activation action needs to be performed before activation of the whole-aircraft ballistic parachute. The aircraft also receives a whole-aircraft ballistic parachute activation request. The aircraft then issues a command to perform the pre-activation action and then activates the deployment of the whole-aircraft ballistic parachute. The aircraft then issues a command to perform a post-activation action.

A fuel tank comprises an interior wall, a sump, and a baffle that comprises a center fitting, a full-length containment petal, a partial-length containment petal, a dump tube. The full-length containment petal comprises a full-length side edge, extending radially outward from the center fitting. The partial-length containment petal comprises a partial-length side edge, extending radially outward from the center fitting. The dump tube is connected to the sump. The full-length side edge of the full-length containment petal is longer than the partial-length side edge of the partial-length containment petal. All of the partial-length side edge of the partial-length containment petal is attached to a linear portion of the full-length side edge of the full-length containment petal.

Disclosed herein is a method that comprises detecting that a rate of decrease in fuel quantity for an aircraft exceeds a previously-determined baseline rate of decrease in fuel quantity for the aircraft by a threshold rate during a corresponding segment of flight of the aircraft. The method also comprises determining that a fuel jettison setting for the aircraft is enabled in response to the detected increase in the rate of decrease in fuel quantity. The method further comprises determining that an angle of one or more flaps of the aircraft satisfies a threshold angle. The method additionally comprises generating an alert indicating possible fuel contamination of the one or more flaps due to jettisoned fuel.
