snip In idle, with the prop at flat pitch, it feels too draggy and comes down like a rock. With it at high pitch, it seems to have too optimistic a glide ratio. What's the happy medium? I'm a little confused by this portion of your question, and a couple of the replies. I have never actually messed around a bunch with airspeed/descent rate/idle engine/prop rpm, but am pretty familiar with how a typical pressure-to-increase pitch constant-speed prop/governor works. Somewhere around 1600-1800 rpm, the prop governor ceases to output enuff pressure to change/maintain the propeller pitch, and the propeller goes to flat pitch. I've seen it on a gov bench, and on approach-to-land. Whether or not the engine is "running" if the rpm is below this range, moving the prop control has no effect on the pitch of the prop. TC snip |
