The A400M defensive aids Sub-System (DASS) includes a radar warning receiver, missile launch and approach warning, and chaff and flare decoy dispensers.
The analysis of the safe separation of flares from A400M within its flight envelope is required as part of the certification process of A400M DASS.
This process includes the validation of the model used by the Aerodynamics Department to calculate the theoretical flare trajectories.
During 2017, it was required to validate the trajectory ejected from dispersers located on the nose of the aircraft, and in this case it was necessary to use external cameras installed in a chase aircraft to cover the completed trajectory. The aim of this document is to present a methodology used to calculate a real case of flares trajectories on A400M ejected from front dispensers using 2 external cameras installed in a chase aircraft.
