Hi all,
Mike said,
< I asked Francis Donaldson of the PFA for advice on the settings for VP
props, and he immediately sent me a copy of the instructions he had issued
last year in connection with a Permit to Test. In this case it was for a
Europa/Rotax/Kremen 2000 set up>
I think it must have been my Woodcomp CS 2000 installation on G BYSA that
F.D. contrived these instructions for. At the time I cursed about the delay, and
the extent of the testing required, but I believed them to be common for all
CS props. He insisted that the prop could not allow the engine to over rev in
the climb state even at its' finest setting. In fact in the variable pitch mode
the prop can be made to go finer than the finest constant speed setting. It
is the finest setting in that VP mode that the engine speed cannot not be
allowed to exceed the limit.
I did find the dive to max knots with the pitch set to course and the engine
idling, an interesting experience. You have to dive very very steeply,
monitor the airspeed, and note the engine revs with the ground coming up at you
fast. As I recall, the revs never got anywhere near the max, so I am confident
the
my engine will not over rev in a dive. If it does, I don't want to be in it.
Has anyone else done this test with a Woodcomp? If so, did they experience
the same?
Cheers Bryan Allsop
