Even when there's no pitch applied to the rotors? Even though my old man was in army aviation (a lonnnnggggg time ago) and i was around helo's a bunch, they were never running therefore, i never dealt with rotor wash. Just always assumed when they were "idling" with no pitch, they just made a bunch of noise but really didn't move any air.


Oh yeah.... we do what we call FPG 100 (flat pitch ground 100%) all the time which is rotors turning at 100% engine power but flat pitch so there's no lift. There's a lot of checks and stuff you HAVE to do in preflight with and without rotors turning that takes a good bit of time which is why they usually get rotors turning ASAP because once the VIP is on board you want to be airborne, not sitting on the ground running through your checks. Then you're just a sitting duck.
