4takeoff,
Don't let that put you off applying. As long as you know why you failed FEAST first time, put that to use and do better! You will possibly have to inform the IAA in your application, that you previously failed with NATS, however, as far as I know, there is no cross "pollination" of information between NATS and the IAA, they are two independant organisations, in different jurisdictions. So good luck
Anyone else with opinions, please chime in and help here
