Didn't find another thread quite like this, however if there is and I missed it please merge. Here at Ft Rucker I've had a few things IPs told as gospel that I questioned and later they somewhat retracted their statements, though never saying they were wrong of course
The biggest one was when I had an IP tell me that because of the lift equation having V being squared, and with the OH-58/TH-67 having close to a 1:7 main to tail rotor ratio, that by drooping the main rotor by 1%, you would lose 49% of your tail rotor effectiveness. My sitck buddy and I looked at each other immediately as our wheels started turning. Luckily he was an aeronautical engineering major and that night went home and started working equations in his off time (I'll never understand engineers). Anyway, the next day he came back with two pages full of diagrams and charts and equations that made my head explode, proving that was not a true statement at all. The IP then backpedaled and said that he was just saying that to scare us from drooping the rotor.
Anybody have any similar stories?
