AvSport of Lock Haven Precession Precision Presentation Copyright © 2015 Many pilots report (especially when flying Light Sport Aircraft) that raising the nose causes the plane to yaw in one direction, and lowering it yaws them in the opposite direction. This gives LSAs a reputation for being instable (or squirrely). In fact, these aircraft are merely obeying natural laws. In this FAA Wings Webinar, a retired physics professor will teach you how to anticipate, detect, and conquer gyroscopic precession. RATIONALE:

AvSport of Lock Haven Precession Precision Presentation Copyright © 2015 For purposes of this course, we will consider the direction in which the aircraft is traveling to be: The X-axis The Y-axis The Z-axis Any axis we choose None of the above

AvSport of Lock Haven Precession Precision Presentation Copyright © 2015 If the aircraft is traveling down the runway (into the page), and you raise or lower the nose, the plane will precess in: The X-axis The Y-axis The Z-axis All three axes None of the above
