Techniques for analyzing aircraft data. An aircraft dataset is utilized from an operational source. The aircraft dataset is parsed into a data field. An acceptable range of values for the aircraft dataset within the data field is determined to define a threshold for the aircraft dataset. A dynamic trigger is automatically activated to indicate a maintenance alert when the threshold is crossed. A performance indication is derived for the operational source by determining one or more performance trends of the aircraft dataset. A notification having a status level indicative of a maintenance condition for the operational source is associated with the maintenance alert. The performance indication and the notification are combined into an electronic report that forecasts need for preventative aircraft maintenance, and the electronic report is automatically delivered to a predetermined location for retrieval by a consumer.

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.

The invention belongs to the aircraft maintenance technology, and particularly relates to a repairing method for a honeycomb sandwich structure. The repairing method includes the steps that firstly, a placement layer and a honeycomb at the damaged portion are ground away, and a lower panel can not be damaged; secondly, a new honeycomb is prepared, and the surface of the honeycomb is glued; thirdly, the honeycomb is put in a cavity of the original honeycomb after being processed; and finally, placement layer replacement is carried out according to the original placement layer. Prepreg, glue film and glass cloth can not be spliced but in seamless butt joint. When the repaired structure is a surface concave as shown, the pneumatic outline can be repaired through filler. Raw materials are used for replacing the honeycomb and the placement layer, and the placement layer is repaired through a wet method. The strength design requirement is met, the structural weight after repairing is reduced, and good compatibility can be kept.
