(2) Purpose. This graph is used to determine range in nautical miles for full main tanks, given pressure
altitude in feet and true airspeed in knots.
bb. Endurance Proile - Full Main Tanks.
(1) Description. The Endurance Proile - Full Main Tanks graph (Fig. 7-83) depicts endurance, allowing
fuel for start, taxi, runup, cruise climb and descent, and 45 minutes fuel reserve.
(2) Purpose. This graph is used to determine endurance in hours for full main tanks, given pressure
altitude in feet and true airspeed in knots.
bc. Range Proile - Full Main and Aux Tanks.
(1) Description. The Range Proile - Full Main and Aux Tanks graph (Fig. 7-84) depicts range, allowing
fuel for start, taxi, runup, cruise climb and descent, and 45 minutes fuel reserve.
(2) Purpose. This graph is used to determine range in nautical miles for full main and aux tanks, given
pressure altitude in feet and true airspeed in knots.
bd. Endurance Proile - Full Main and Aux Tanks.
(1) Description. The Endurance Proile - Loiter Power at 1700 RPM graph (Fig. 7-85) depicts endurance,
allowing fuel for start, taxi, runup, cruise climb and descent, and 45 minutes fuel reserve.
(2) Purpose. This graph is used to determine endurance in hours for full main and aux tanks, given pres-
sure altitude in feet and true airspeed in knots.
be. One Engine Inoperative Max Cruise Power at 1700 RPM.
(1) Description. The One Engine Inoperative Max Cruise Power at 1700 RPM tables (Fig. 7-86 through
7-93) show fuel low, airspeed, and torque for various light conditions.
(2) Purpose. These tables are used to determine fuel low per engine, total fuel low, indicated airspeed,
and true airspeed, given pressure altitude in feet, indicated free air temperature and free air temperature in degrees
Celsius, aircraft weight in pounds, and torque per engine in percent. During operation with ice vanes extended,
torque will decrease approximately 10%, fuel low will decrease by approximately 6%, and true airspeed will be
reduced by approximately 10 knots.
bf. Time, Fuel, and Distance to Descend.
(1) Description. The Time, Fuel, and Distance to Descend graph (Fig. 7-94) depicts the time, fuel, and
distance to descend.
(2) Purpose. This graph is used to determine the time, fuel, and distance required to descend, given the
beginning and ending pressure altitudes in feet.
bg. Climb - Balked Landing.
(1) Description. The Climb - Balked Landing graph (Fig. 7-95) depicts rate of climb to be expected after a
balked landing.
(2) Purpose. This graph is used to determine the rate of climb in feet per minute and climb gradient in
percent, given the free air temperature in degrees Celsius, pressure altitude in feet, and aircraft weight in pounds.
For operation with ice vanes extended, rate of climb will be reduced by approximately 300 feet per minute. Enter
the graph at the pressure altitude from which a go-around would be initiated.
bh. Normal Landing Distance - Flaps Down.
(1) Description. The Normal Landing Distance - Flaps Down graph (Fig. 7-96) depicts normal laps down
landing distance.
