The FDR used in our study reports important parameters. However, for this study, only those parameters which are relevant for engine performance calculations are Size: 2MB.This data may then move to an Air Data Computer, or to a data bus before proceeding to the aircraft’s Flight Data Acquisition Unit (FDAU).

The FDAU serves as a type of funnel that takes all of this collected information, puts it in a standard format (normally ARINC ) and writes it to the FDR.

One important aspect of flight-testing of any aircraft or helicopter (or even a missile) is to generate the data for estimation of its stability and control derivatives. In this sense, parameter estimation is an important tool for flight test engineers and data analysts to determine the aerodynamic characteristics of new and untested aircraft.
