Question: If the engine in a single quits in cruise, what should I do with the throttle, propeller, and other controls to get the best glide?
Answer: Most singles can glide eight times their height above the terrain. If you’re at 7,500 feet and the local elevation is 700 feet, you’re about one and a quarter miles above the ground, so don’t pick a place to land outside a 10-mile radius. Don’t count on achieving the longest possible lide—better a nearby cornfield than a distant runway.

Slow to your best rate-of-climb speed. If the prop doesn’t stop of its own accord, let it windmill. To reduce drag from the windmilling propeller, open the throttle fully and set a constant-speed prop to the lowest possible rpm (vernier all the way out).
If you’re landing in the rough, turn off fuel to the engine. Slide your seat as far back as you can while still holding the yoke, and make your lap and shoulder belts as tight as possible. Keep the flaps and gear retracted until you’re in position to land, then use full flaps.
Otherwise, touch down on the numbers.
