The availability of flight data used in the maintenance of aircraft engines is enhanced by exporting data from the database of an engine condition monitoring program to a long term database. The data export is accomplished by first reading a time file to determine the last date and time that data was successfully exported to the destination database. The program database is then searched for data that is new or changed since the last successful export. Any data found in searching the program database is retrieved and exported to the destination database. After a successful export, the date and time of the successful export is updated in the time file.

Aircraft flight data collection is enhanced by changing the data sampling rate as a function of an operational condition of the aircraft, such as its flight phase. An algorithm is used to determine the flight phase. Then, the data is collected at a first sampling rate when the flight phase is one of a first set of flight phases and collected at a second sampling rate when the flight phase is one of a second set of flight phases. The second sampling rate is greater than the first sampling rate to maximize the data storage capacity of the system. Generally, the higher sampling rate is used with transient flight phases such as takeoff and thrust reverse.
