but the 225's are coming with the Eurocopter version of the same. I assume it is fitted under licence but not sure - Its a basically identical system.
No, the AFDS mod fitted to Bristow EC225s is the same Bristow mod that is fitted to the 332Ls etc, with a duplex electronics pack that requires at least 2 float switches to operate before firing, and a short delay.
All other 225s with AFDS have Eurocopter's mod which is less clever - a simplex system, and requiring only 1 float switch activated to fire the floats, so a few false activations, and there is no delay between the switch and firing the floats.
