(fig. 7A-13) provides the one engine inoperative climb
performance weight limit as a function of field pressure
altitude and temperature.
(2)
Purpose. This graph is used to determine
the maximum weight at which the aircraft can take off
and still meet the minimum one engine inoperative rate
of climb capability, given field pressure altitude in feet
and temperature in degrees Celsius. Refer to the Climb
- One Engine Inoperative graph for the actual climb
capabilities applicable to the temperature and altitude
being considered. For operation with ice vanes
extended, reduce the weight determined from the graph
by 1800 pounds.

Maximum Take-off Weight To Achieve Positive
One Engine Climb At Lift-off - Flaps Up.
(1)
Description.
The
Maximum
Take-off
Weight to Achieve Positive One Engine Inoperative
Climb at Liftoff - Flaps Up graph (fig. 7A-14) provides
the one engine inoperative liftoff climb performance
weight limit .as a function of field pressure altitude and
temperature.
(2)
Purpose. This graph is used to determine
the maximum weight at which the aircraft can take off
with flaps up, have an engine failure, and be able to
attain a positive rate of climb at liftoff, given field
pressure altitude in feet and free air temperature in
degrees Celsius. For operation with ice vanes extended,
add 1700 feet to field pressure altitude before entering
graph.

Speed - Flaps Up.
(1)
Description.
The
Maximum
Take-off
Weight as Limited by Tire Speed - Flaps Up graph (fig.
7A-15) provides. the takeoff tire speed weight limit as a
function of field pressure altitude, temperature, and wind
component.
(2)
Purpose. This graph is used to determine
the maximum weight at which the aircraft can take off
and
not
exceed
tire
limitations,
given
free
air
temperature in degrees Celsius, field pressure altitude in
feet, and head or tail wind component in knots.
o.
Take-off Speeds (KIAS) - Flaps Up.
(1)
Description. The Take-off Speeds (KIAS)
- Flaps Up table (fig. 7A-16) allows selection of the
proper takeoff speeds for takeoff weight, pressure
altitude, and temperature.
(2)
Purpose. This table is used to determine
V1, VR, V2. and V50 For each takeoff, given free air
temperature in degrees Celsius, field pressure altitude in
feet, and takeoff gross weight in pounds.

Take-off - Flaps Up.
(1)
Description. The Take-off Distance Over
50 Foot Obstacle - Flaps Up graph (fig. 7A-17) depicts
the
relationship
of
takeoff
distance
to
free
air
temperature, field pressure altitude, takeoff weight,
runway gradient, and wind component.
(2)
Purpose. This graph is used to determine
the ground roll distance or the total distance required to
take off and clear a 50 foot obstacle, given free air
temperature in degrees Celsius, field pressure altitude in
feet, aircraft takeoff weight in pounds, runway gradient in
% up or down, and head or tail wind component in knots.
For operation with ice vanes extended, increase total
distance by 33%. Consult Maximum Take-off weight -
Flaps Up -as limited by Tire Speed graph for possible
tailwind prohibitions.
q.
Accelerate-Stop - Flaps Up.
(1)
Description. The Accelerate-Stop - Flaps
Up graph (fig. 7A-18) depicts the distance required to
accelerate to decision speed (V1) then stop.
(2)
Purpose. This graph is used to determine
the total runway length required to accelerate to V1
(takeoff decision speed), set power levers to ground fine
at V1, then use maximum braking (without sliding tires)
until the aircraft is stopped, given free air temperature in
degrees Celsius, field pressure altitude in feet, takeoff
weight in pounds, up or down runway gradient in %, and
head or tail wind component in knots. For operations
with ice vanes extended, increase distance by 7%.

r.
Accelerate-Go - Flaps Up.
(1)
Description. The Accelerate-Go Distance
Over 50 Foot Obstacle - Flaps Up graph (fig.7A-19)
depicts the total distance required to accelerate to
takeoff airspeed, have an engine failure, then continue
the takeoff until 50 feet above the runway.
(2)
Purpose. This graph is used to determine
the total distance required to accelerate to V1 (takeoff
decision speed), have an engine failure, then continue
the climb until 50 feet above the runway. For operation
with ice vanes extended, increase distance by 35%.
