Upon engine failure after reaching 95 KIAS on takeoff, the multi-engine
pilot has a significant advantage over a single-engine pilot, for he has a
choice of stopping or continuing the takeoff. This would be similar to the
choice facing a single-engine pilot who has suddenly lost slightly more
than half of his takeoff power. In this situation, the single·engine pilot
would be extremely reluctant to continue the takeoff if he had to cl imb
over obstructions. However, if the failure occurred at an altitude as high
or higher than surrounding obstructions, he would feel free to maneuver for
a landing back at the airport.
Fortunately, the airplane accelerates through this "area of decision" in
just a few seconds. However, to make an intelligent decision in this type
of emergency, one must consider the field length, obstruction height, field
elevation, air temperature, headwind, and takeoff weight. The flight paths
illustrated in Figure 3-2 indicate that the "go no-go area of decision" is
bounded by: (1) the point at which 95 KIAS is reached and (2) the point
where the obstruction altitude is reached. An engine failure in this area
reqUires an immediate decision. Beyond this area, the airplane, within the
limitations of one engine inoperative climb performance shown in Section 5 ••
may be maneuvered to a landing back at the airport.
