This topic remains confusing because of the complex physics(classical mecha=
nics) and the redundant aviator terminology.=20
It requires periodic review.=20
Here's a clasic source online:
Pilot's Encyclopedia of Aeronautical Knowledge - Google Books ResultComment=
s
I think the issue in this thread is torque, in the pilot sense...
The pilot's term "torque" has 4 components, one of which is P-factor
And another of which is "torque", in the physicist's sence of the word.
Gyroscopic precesion and slipstream also affect my 4P on takeoff,
(especially with a strong right crosswind on takeoff from OSH when you are =
watching for many other things!) If you rotate in pitch,, rapidly, for take=
off after smoothly applying power, which way will your nose swing in yaw? B=
e careful, its not a taildragger....
The lack of nosewheel steering has a big effect on technique- good discussi=
on!
Slow transitions, rather than "step inputs" are always a good start in any =
flight test or experimental arena.
Thanks
Bill Miller
