j2 Flight Flight Matching The j2 Flight Plug-In is used to review flight test data and to identify the model corrections required. One of the challenges related to flight test matching is that establishing a great match for one flight condition and using that to predict the next often leads to less than desirable results starting a manual and iterative solution loop. With j2 Flight, multiple test points can be analysed as a batch and the optimum solution for all cases found. The detailed analytical approach provided by j2 Flight introduces a teachable, robust and repeatable process. This reduces the pressure and requirement on heavily experienced engineers who have learnt through experience which aspects of model corrections work. By having complete control of the model, we are able to perform a lot more activities mathematically. Process The matching process developed by j2 Aircraft Dynamics follows a very similar approach to that which is used across multiple companies already. However, with some of the extra steps/details that are available, we are able to reduce the burden on experience, and the manual aspects of flight matching by up to 30%. All the process can be run as batches of test points to avoid iterative divergent solution loops. Import Data The initial stage is the import of flight test data into the j2 Universal Database. Data can come in many formats with various signal names and in a range of units. The import stage allows for the conversion of signals from the FDR into SI units.
