A Flight Risk Management System (“FRMS”). The system provides supplementary preflight and in-flight guidance to relatively inexperienced owner / operators of high performance aircraft. A pilot wishing to enroll in the FRMS must have an aircraft equipped with an in-flight data recorder capable of monitoring the aircraft's state and communicating this state to an FRMS dispatcher. The dispatcher analyzes each flight before its commencement and imposes restrictions designed to promote flight safety. The dispatcher monitors the flight in progress to ensure the pilot's compliance with all directives. For most enrollees, participation in the FRMS is a mandatory condition precedent to the pilot's insurance coverage. Thus, the potential loss of insurance coverage enforces compliance. In the preferred embodiment, the FRMS manages pilot training, pilot performance, aircraft maintenance, and flight risk assessment.
