After its retirement from the French military service in 2022 and more than 1.000.000 flight hours combined, it is time for the Transall to live a second life in Flight Simulator 2020! It accomplished thousands of missions, flew above hundreds of countries and has been involved in numerous humanitarian missions. We have put a lot of effort to improve even more our quality standards compared to our previous products. The great complexity of the aircraft and its military-designed systems forced us to adapt our development processes accordingly. Hence, our Transall includes a big amount of bespoke systems and does not re-use existing generic avionics from the simulator. Our work is based on the C160 NG/R version which is the most modern one to have been operated in French Air Force.
