GARDN II Projects (2014-2019)

New 4th Round Project

CMC- 21 (Project Extension):  Flight Management Performance Optimization III



The main environmental benefits of the research projects presented are to reduce overall CO2 emissions, flight costs and noise by improving the capabilities of the Flight Management System (FMS) and the large-scale deployment of the FMS on several aeronautical platforms.

The second project, improving FMS capabilities, is expected to result in fuel and noise reductions.


The algorithm developed by the LARCASE team (ETS) and validated using actual and realistic atmospheric data provided by Environment Canada is able to collect information during the flight from various avionics systems aboard the aircraft and perform various analyses to estimate the actual performance of the aircraft without requiring detailed performance characteristic from the aircraft manufacturer. The results can also used to evaluate the accuracy of the aircraft model encoded in the FMS (usually based on aircraft manufacturer performance figures). When the algorithm detects significant errors between the FMS predictions and the measured performance during the flight, a correction is automatically applied to update the model in order to increase flight predictions accuracy, thus providing an increase performance of the optimization functions.

In addition, modifications applied to the FMS software allow military customers to take advantage of FMS optimization functions, and therefore allow the optimized solution to be deployed to a larger number of aircraft.
