<name>Engine Failure</name>
|
|
|
|
<description>Engine failure is very rare in flight simulators, but a risk in real life.
|
|
|
|
|
|
The tutorial starts with you cruising at 3000 ft near Hilo. A total engine failure will occur, with no possibility of restart - black smoke, chunks of metal pushed out of the cowling.
|
|
|
|
Glide the aircraft to the nearest airport and make a successful emergency landing. You must manage your altitude and fly a normal pattern from "abeam the numbers". Don't deploy flaps until you have the runway "made".
|
|
|
|
The Cessna 172 glides at a ratio of 9:1 at a best glide speed of 65 kts IAS. The glide ratio assumes no flaps and a "windmilling" propeller. If you fly any faster or slower, or have flaps deployed, the glide rate will be worse.
|
|
|
|
PHTO (Hilo) is within glide distance. Try to land at PHTO.
