Also, look up "beta mode thrust" where the prop is put into reverse pitch
in flight...... gives one hell of a rate of descent.....can even beat the
parachutists down!

Mind you, it may not appear in the POH.

Even without putting the prop into beta, if you beat the Porter down
you pulled too low. I have several dozen jumps from various Porters
and I frequently remember watching the plane pass us within a few
thousand feet of exit.
