Enter the appropriate graph at the OUTSIDE AIR
TEMPERATURE ~ C. From +30 C trace up until
intersecting the correct PRESSURE ALTITUDE –
FEET line, 4000 feet. Trace horizontally to the left
until intersecting the ENGINE TORQUE AT 2000 RPM
~ PERCENT scale and read the Minimum Takeoff
power.
In this example the minimum takeoff power is
90.2%. Enter the information on the TOLD card.

(7) Configuration. Mark (4 or X) the
appropriate configuration as determined on the back of
the TOLD card. For this example, it was decided to
takeoff with the Flaps UP.
(8) Takeoff Field Length Required. For this
example, enter the actual ACC/STOP distance of
5,900 feet for a 12,600-pound aircraft.
If the weight to accomplish an ACC/STOP had
been the most restrictive weight, then we would enter
the field length that was used on the back of the TOLD
card to determine the maximum takeoff weight to
achieve an acceleration and stop maneuver (6000
feet).
(9) Accelerate – Go Distance. This distance
is advisory only. Use Figure 7-23. Accelerate – Go,
Flaps UP or Figure 7-27, Accelerate – Go, Flaps
APPROACH.

the
graph
at
the
OUTSIDE
AIR
TEMPERATURE ~ ºC, +30 ºC. Trace up until
intersecting the correct PRESSURE ALTITUDE ~
FEET line, 4000 feet. Trace horizontally to the right
until intersecting the REFERENCE LINE. Maintain the
same relative distance between the guidelines and
trace up until intersecting the aircraft takeoff WEIGHT
~ POUNDS line. Trace horizontally to the right and
read the accelerate – go distance.
In this example, the takeoff weight is planned at
12,600 pounds. The accelerate – go distance is
8,800 feet.
Enter the distance, 8,800 feet, in the appropriate
block on the TOLD card.
As already stated, Accelerate-Go distance is
advisory only. However, a point 35 feet above the end
of the departure runway is normally the point from
which climb gradients are calculated. Therefore,
regardless of all other prudent performance planning, if
an engine fails at V1 on this example departure the
aircraft will not be capable of clearing all obstacles. If
weather conditions are at or near minimums, the crew
should consider some other options to assure the
capability to accomplish an acceleration and go
maneuver such as:
Decreasing the load and/or fuel.
Reducing takeoff weight and using flaps 40%.
Delaying the departure for more favorable
weather conditions.
(10) V1 (Takeoff Decision Speed) / Vr (Rotation
Speed). In the C-12 aircraft V1 and Vr are always the
