Single Engine Takeoff - Cessna 310 1975 Owner's Manual

SINGLE ENGINE TAKEOFF
Figure 3-2
At sea level standard day, with zero wind and 5500
pounds gross weight, the distance to accelerate to 92 KIAS
and stop is 3635 feet, while the total unobstructed dis-
tance required to takeoff and climb over a 50 foot obsta-
cle after an engine failure at 92 KIAS is 3630 feet. This
total distance over an obstacle can be reduced slightly
under more favorable conditions of gross weight, headwind,
or obstruction height. However, it is recommended that in
most cases it would be better to discontinue the takeoff,
since any slight mismanagement of the single-engine pro-
cedure would more than offset the small distance advantage
offered by continuing the takeoff. The advantage of dis-
continuing the takeoff is even more obvious at higher alti-
tudes where the corresponding distances are 4065 and 5250
respectively, at 2000 feet. Still higher field elevations
will cause the single-engine takeoff distance to lengthen
disproportionately until an altitude is reached where a
successful takeoff is improbable unless the airspeed and
height above the runway at engine failure are great enough
to allow a slight deceleration and altitude loss while
the aircraft is being prepared for a single-engine climb.
During single-engine takeoff procedures over an obsta-
cle, only one condition presents any appreciable advantage;
this is headwind. A decrease of approximately 1% in ground
distance required to clear a 50 foot obstacle can be gained
for each 1 knot of headwind. Excessive speed above best
single-engine climb speed at engine failure is not nearly as
advantageous as one might expect since deceleration is rapid
