Good question, Lynn. You're correct, but unless the prop has a pitch
indicator--most NSI units don't-- one sets it by a simple process prior to
takeoff, but sometimes it needs a bit of a tweak during the takeoff process
to get the correct takeoff rpm. Not a big deal at all, but for someone who
hadn't used one previously, it could be. Again, it's just speculation. I
have no idea what actually happened. As for the prop going into reverse, I
doubt it. That prop has built in interlocks so that it cannot go into beta
above a certain rpm. I think it's about 1200 prop rpm to be exact, but I'd
have to check.
