Determining Air Speed for a Glider Flight

Video Transcript

" Hi! My name is Gene; I'm glider flight instructor on behalf of Expert Village. If you focus on the air speed, the green arc is the maneuvering speed of the airplane. When you get into the yellow arc, that's the caution area. That's the point where complete deflection of the controls at high speed could damage the airplane. In the green arc, full deflection of controls is not supposed to damage the airplane. So in the yellow arc you have to be careful, in the green arc you have a normal flying mode, and when you get to the red line, that's a do not exceed speed. That's the point where if you exceed the red line, in this case, 100 miles an hour, then the wings may come off the airplane, which is not a good situation. We never fly above red line; not in the airplane. "
