Okay, have to agree that for all donkeys working i agree that the Flap Retraction Altitude is a hang back to some unknown reason that we all do without really questioning it, and that 400ft agl is most likely chosen because it coincides with the OEI acceleration altitude to get to V2+10 and clean up etc., etc. - i know it's not correct, but what sort of time (seconds) does it take on average i wonder to get from V1 to V2+10 etc., etc when compared to reaching 400ft agl?? probably about the same in my CJ ??
