Slow flight

Slow flight is a portion of an airplane's performance envelope above the speed at which the plane will stall, but below the speed for best glide. In this speed range the wing requires a large angle of attack in order to generate enough lift to keep flying, so much so that the induced drag from the wing means that more power is needed than at higher speeds. An aircraft in slow flight appears "sluggish" and is easy to trip into a stall, so practice in slow flight is an important part of flight training.
