Document Title: Airmen Transition to Experimental Airplanes
Summary: This revision of AC 90-109 adds increased emphasis on loss of control issues when transitioning to unfamiliar aircraft. New text focuses on transitioning to other type-certificated aircraft, instead of just experimental aircraft. We added emphasis on awareness of differences in aircraft equipment, suc as advanced avionics and complex equipment like retractable landing gear. We added text identifying the availability of General Aviation Manufacturers Association (GAMA) Publication 5, which provides master syllabi for transition training. Lastly, we made updates to safety data and made editorial and style corrections.
