"dont know what airplanes you fly or intend to fly, but those questions you complained about might be relevant in your future operations..."
17000 plus of military and airline flying and I have never known or cared about the difference between 2 types of hydroplane and although I understand that an engine out in a twin is a serious loss of performance, when the throttles are at the stops with max EPR and we are at best speed engine out and in balance, knowing a % loss of climb is irrelevant.
