Aye your right CB the tail wing on a tomahawk needs plenty of boost pressure.
But this method has been effectively been used by 3 IR students to de-ice a cougar. Must admit there was words said by the tower when we taxied out.
Also the mushroom cloud appearing above the plane under a apron light when we shut down for a crew change was also noted by the tower.
Mind you the student who thought it was funny to taxi forward when the instructor needed to go while holding during a stop -pee and go and then request the runway lights be turned up full.... Brave lad that one
For those that haven't done a IR it is very possible you can end up sitting in a freezing cold plane being bounced around for 5 hours.
