Flight characteristics and controllability associated with maneuvering to a landing with inoperative powerplant(s).
Bottom line
Glide airspeeds that are too slow or too fast may result in the airplane not being able to make the intended landing spot, flat approaches, hard touchdowns, floating, overruns, and possibly stalls and an accident.
Key numbers
| Number | What it means |
|---|---|
| 10 percent (100 feet if the descent rate is 1,000 feet per minute), in the event of a complete power failure | Level-off lead |
| Power applied as the 10 percent lead value appears on the altimeter, in simulated power failure training | Simulated failure |
