Flight characteristics and controllability associated with maneuvering to a landing with inoperative powerplant(s).
Bottom line
A glide is a basic maneuver in which the airplane loses altitude in a controlled descent with little or no engine power. Forward motion is maintained by gravity pulling the airplane along an inclined path, and the descent rate is controlled by the pilot balancing the forces of gravity and lift.
Key numbers
| Number | What it means |
|---|---|
| 10 percent (100 feet if the descent rate is 1,000 feet per minute) to slow the descent before landing after a complete power failure | Lead factor |
| approximately 100 feet above the target altitude, in a 500 fpm rate of descent with a desired final airspeed higher than the glide speed | Practice glide |
