I'm no aeronautical engineer.........but can someone explain to me why it would be so hard to route some of that tornado force downwind generated by the rotors into the cockpit? Some sort of small intakes that could be routed to increase airflow over crucial electronics........like, oh I don't know, flight controls? You have a fucking hurrican above you washing downwards over your aircraft, and that's in stationary flight. Add normal flight and you have available airflow coming from the front and from up top.........why the need for an airconditioner?
