n. Maximum Take-Off Weight as Limited by Tire Speed - Flaps Up.
(1) Description. The Maximum Take-off Weight as Limited by Tire Speed - Flaps Up graph (Fig. 7-15) pro-
vides the takeoff tire speed weight limit as a function of ield 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, ield 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. 7-16) allows selection of the proper
takeoff speeds for takeoff weight, pressure altitude, and temperature.
(2) Purpose. This table is used to determine V 1 , V R , V 2 , and V 50 for each takeoff, given free air
temperature in degrees Celsius, ield pressure altitude in feet, and takeoff gross weight in pounds.
p. Take-Off - Flaps Up.
(1) Description. The Take-off Distance Over 50 Foot Obstacle - Flaps Up graph (Fig. 7-17) depicts the
relationship of takeoff distance to free air temperature, ield 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, ield 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 31%. Consult Maximum Take-off Weight as Limited
by Tire Speed - Flaps Up graph for possible tailwind prohibitions.
q. Accelerate-Stop Flaps Up.
(1) Description. The Accelerate-Stop - Flaps Up graph (Fig. 7-18) depicts the distance required to accel-
erate to decision speed (V 1 ) then stop.
(2) Purpose. This graph is used to determine the total runway length required to accelerate to V 1 (takeoff
decision speed), set power levers to ground ine at V 1 , then use maximum braking (without sliding tires) until the
aircraft is stopped, given free air temperature in degrees Celsius, ield 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%. Consult Maximum Take-Off Weight As Limited by Tire Speed - Flaps Upgraph
for possible tailwind prohibitions.
r. Accelerate-Go - Flaps Up.
(1) Description. The Accelerate-Go Distance Over 50 Foot Obstacle - Flaps Up graph (Fig. 7-19) 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 V 1 (takeoff deci-
sion 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%. Consult Maximum Take-Off Weight As Limited by Tire Speed - Flaps
Up graph for possible tailwind prohibitions.
