It all just makes me a little bit angry. Heard a rumour that the A400M bods spent an absolute fortune (UK contribution £50M +) redesigning the engine so that it has an 'operationally essential' brake to stop the twirlly bits spinning on the ground. How many sets of DAS/sets of ballistic matting/sets of tank foam would that have bought? So instead, as Flight International reported, we will have only 9 of 25 ac fitted with DAS.
Hope it swaps easily between aircraft as those 9 sets are sure going to be in demand....
