Best Glide Airspeed


Introduction to Glider Flying > Launch and Recovery Procedures and Flight Maneuvers > Best Glide Airspeed

Best glide (Lift/Drag) airspeed is defined as the air-speed that results in the least amount of altitude loss over a given distance. This allows the glider to glide the greatest distance in still air. This performance is expressed as glide ratio. The manufacturer publishes the best glide airspeed for specified weights and the resulting glide ratio. For example, a glide ratio of 36:1 means that the glider will loose 1 foot of altitude for every 36 feet of forward movement in still air at this airspeed. The glide ratio will decrease at airspeeds above or below best glide airspeed. The best glide speed can be found from the glider polars in chapter 5—Performance Limitations.

• Improper determination of best glide airspeed for given condition.
• Failure to maintain proper pitch attitude and airspeed control.
