Saw a rather scary video of flight ice trials carried out on the J41 by BAe. Was after the Roslawn ATR prang. Also ATR had another prang due to full flap and tail plane icing, thing that was in Italy?
BAe did loads of work on tail plane icing. Know the ended up changing the elevator profile and leading edge design on the J41.
Anybody that was at BAe at the time for comment?
