REFLECTOR: Yoke elevator friction load

[Hiroo Umeno]

My plane has a dual-yoke system.  As I was getting the plane ready for
final inspection, and cycling through all the controls, I noticed that
my elevator control was quite "heavy".  In that, cycling the trim did
not really move the elevators on its own but rather applied bias
pressure to the elevator system so that when I do move the control by
hand, it will settle in a different position.
