Improving Your Glide

When a single's engine quits, you're a glider. Maximizing the time you can stay aloft to maneuver for a landing while traveling the most distance can require some finesse.

Key Takeaways:

  • The core emergency procedure for a single-engine aircraft failure is summarized by the "Glide, Grass, Gas" mnemonic: maintain best glide speed/attitude, select a landing spot, and attempt an engine restart.
  • The article emphasizes maximizing "finesse" (wing efficiency or L/D ratio) during the "glide" phase, recommending pilots focus on setting the correct nose-down attitude rather than strictly monitoring airspeed for optimal performance.
  • Pilots should prioritize quickly establishing the best glide attitude, consider wind effects on ground performance, aim high for chosen landing sites, and use smooth, coordinated control inputs to conserve energy and maximize glide time.

My first flight instructor’s words from decades ago are stuck with me: “Glide, grass, gas,” he said, and then repeated it. “Glide, grass, gas.” He was talking about engine failures, and these three little words are a nice mental checklist for what to do when the engine of a single-engine airplane stops. Glide: Fly at the airplane’s “best glide” speed. Grass: Pick a place to land. Gas: Try to get the engine restarted.

I’ve never had to use Tom’s advice, but I still use his words when I teach my students what to do if an engine fails. “Glide, grass, gas, Steve,” I say, and repeat, “Glide, grass, gas.” If you come to me for a flight review, we’ll review it on the ground and, of course, in the air.
