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 "Glide, Grass, Gas" mnemonic serves as a vital mental checklist for single-engine failure: prioritize achieving the best glide, selecting a landing spot, and attempting an engine restart.
  • Effective gliding, termed "finesse," is achieved by setting the correct aircraft attitude (typically a few degrees nose-down) rather than rigidly chasing a specific airspeed, which optimizes glide performance and allows pilots to focus on external factors.
  • Maximizing finesse involves smooth, deliberate control inputs, avoiding wasteful maneuvers, and aiming high for the chosen landing site, recognizing that being slightly fast or high offers a safety margin in an emergency.

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.
