What is the glide speed?

Glide speed is the speed that gives the best lift-to-drag ratio in a power-off glide, maximizing how far you can glide before reaching the ground. It’s the speed you’d choose to travel the greatest distance if you had to glide. In this scenario, 135 (knots, typically) is the speed that yields the best glide for the aircraft’s performance data, so it’s the correct choice. Slower (like 120) would increase induced drag and reduce glide distance, while faster speeds (like 150 or 165) increase parasite drag and also shorten the glide distance.
