FOR THE FOR THE PARTICULARPARTICULAR

FLIGHTFLIGHT

In airplanes for which the manufacturer does not provide the optimum glide speed, and with which the pilot is not familiar, it can be determined by experimentation. This can be accomplished by establishing a power off glide and noting the airspeed and vertical speed, and then gradually reducing the airspeed until the vertical speed reaches its minimum and starts to increase. The airspeed at that moment is the best glide speed in still air.
