What if the helicopter was to climb at a very small rate, say, 1 ft/min. Does this thrust without power you speak of suddenly become THP after all? Or just a tinsy winsy bit THP? What if the helo is winching pax up whilst maintaining a steady hover: the AUM increases with every pax. but the aircraft hasn't moved. This requires a change of thrust and engine power of course but
according to you THP remains at zero throughout
What if said helo were to descend at a very small rate. Is it using more THP because it is now moving than it did in the hover. According to you the answer is yes because you say there was zero THP in the hover! Or would you now say it is negative THP?!
What of that old carrier footage where the planes used their prop wash to aid in coming alongside? The aircraft are lashed to the deck. Work is being done on the carrier, THP is being generated, you would probably agree. If during this maneouvre the carrier comes briefly under the influence of a current that halts its progress toward the jetty, does THP magically go to zero and then come back when the current abates? According to you it goes to zero
