1. A method for providing, via an in-vehicle system comprising sensors, adaptive operator assessment and coaching for an operator of a vehicle, the method comprising: determining operational efficiency of the vehicle based on information from the sensors in first and second time frames within a series of timeframes; determining a first desired operator behavior for the first time frame based on vehicle information, sortie information and the information from the sensors; determining a second desired operator behavior for the second time frame based on vehicle information, sortie information and the information from the sensors, wherein the first desired operator behavior differs from the second desired operator behavior; determining that one or more of predetermined behavior categories has occurred or is occurring; assessing an operator's performance based on the operational efficiency of the vehicle in the first time frame and in the second time frame; incrementally changing an operator feedback threshold based upon incremental modification of a plurality of corresponding parameters; and providing a feedback to the operator of the vehicle based on the determined one or more of predetermined behavior categories the assessment, and the operator feedback threshold.
