What does a higher glide ratio imply for engine-out planning?

• A. Shorter distance to landing site.
• B. Longer distance to landing site.
• C. No relation to planning.
• D. It requires more altitude to reach the same distance.

Answer: (B)

Glide ratio tells you how far you can travel forward for each unit of altitude you lose in a glide. In engine-out planning you’re trying to reach a suitable landing site after losing power, so you want to maximize that distance. A higher glide ratio means you can cover more horizontal distance before you run out of altitude, so the landing site can be farther away. That’s why the correct takeaway is that the distance to the landing site is longer with a better glide ratio.

In practice, you achieve this by flying at the best glide speed (to maximize lift-to-drag), keeping the aircraft clean, and minimizing drag. Weight, configuration, and wind also affect how far you can glide, but the core idea remains: a higher glide ratio extends your reachable distance.
