Abstract: A method of evaluating pilot performance receives and processes avionics data at a database system. The database system computes component scores for the pilot based on the avionics data. Each component score represents a performance grade for a pilot-controlled operation of the aircraft. The database system saves the component scores in association with a pilot performance record for the pilot, and calculates an overall score based on the component scores. The overall score represents a flight performance grade for the pilot. The database system saves the overall score in association with the pilot performance record, and generates a report derived from the component scores and the overall score. A graphical representation of the report is communicated to an electronic device.
