It would be good to get more specifics, but what appears odd is that according to Marlboro, their ops havent changed, they just started getting fined....
For the most part, these systems use the ADSB to track the ac....Is there a webtrak set up for this airport in question? If there is, that would be good to look at first, as that system saves historical data.
From the ac system, the Flight Data Acquisition Unit (FDAU) primarily sends the data to the flight recorder, but most have a secondary bus for output. The FDAU can provide data and predefined reports to the cockpit printer, directly to Aircraft Communications Addressing and Reporting System (ACARS) for transmittal to the ground, or to a Quick Access Recorder (QAR) for recording and/or storage of raw flight data.
This is used by the FOQA, so if you have a program like that set up, the data cab be derived from that as well.
