Re: the Official Runway Distance thread


Hello Charlie:

My use of the terms "up" and "down" I have tried to clarify by stating the
position of the trailing edge in relation with the wing's trialing edge. So I
will reiterate in an attempt not to call the reflex position either up" or
"down" since I may have it reversed in terms of how the sailplane folks call

I want to have a nose down attitude upon decent on final. I set there
reflexor control to a forward position. This causes my nose to pitch down because
the main wing is reflexed so that the ailerons trailing edges are down
relative to the main wing. This creates some additional lift in the main wing and
causes the tail to raise / nose to lower.

Upon landing and having three wheels on the deck, the last thing I want to
happen is for the main wing to get airborn for any reason whatsoever other than
upon adding full power. The main wing has been in a state where the wing
had the highest lift potential as described in the previous paragraph. Now
that the plane is a tricycle, I pull the reflex lever back and this causes the
trailing edges of the ailerons to cross neutral and rise above the trailing
edges of the main wing. I'm pretty happy that the main wing is now configured
to have the least amount of lift potential and I am less concerned about
wind gusts causing that portion of the plane from coming up. The tail wheel is
down for the rollout.

So I have attempted to use the terms "Up" and "Down" to describe the effect
on the rear of the aircraft.
