I have been taking a summer multi-engine ground school at the University of Dubuque since May 12th. Tonight was the last class. Some of the class was a review of things I learned in commercial ground school, like aircraft systems. But a lot was new. Multi-engine airplanes have a few important differences from single engine airplanes; mainly, you can lose control of the aircraft if you don’t do the right thing after an engine failure, and also these planes are much more complex. Two engines are not necessarily safer than one. We spent a lot of time going over the pilot’s operating handbook for the Piper Seminole, which I will be training in.
