ENGINE FAILURE
If an engine failure occurs during the takeoff run, the most impor-
tant thing to do is stop the airplane on the remaining runway. Those
extra items on the checklist will provide added safety during a failure
of this type.
Prompt lowering of the nose to maintain airspeed and establish a
glide attitude is the first response to an engine failure after takeoff. In
most cases, the landing should be planned straight ahead with only
small changes in direction to avoid obstructions. Altitude and airspeed
are seldom sufficient to execute a 180
0
gliding turn necessary to return
to the runway. The checklist procedures assume that adequate time
exists to secure the fuel and ignition systems prior to touchdown.
After an engine failure in flight, the best glide speed as shown in
figure 3-1 should be established as quickly as possible. While gliding
toward a suitable landing area, an effort should be made to identify the
cause of the failure. If time permits, an engine restart should be at-
tempted as shown in the checklist. If the engine cannot be resta.rted, a
forced landing without power must be completed.
