8. Using the weight of 9700 pounds with the flaps at 0%, and 9000 pounds with
the flaps at 40%, the accelerate-go distance will be shortened. This in turn
will decrease the minimum gradient of climb value required to clear the
ridge. The allowable take-off weights to meet these requirements are
between 10,600 pounds and 9700 pounds with the flaps at 0%, or between
11,300 pounds and 9000 pounds with the flaps at 40%. Exact weight can be
determined by an iterative process of assuming new weight halfway
between these weights and using the procedures outlined in Steps 3, 5, 6,
7 and 8. Determine new weights for first iteration as follows:
a. Flaps 0%:
10,600 - 9700 = 900
900 ÷ 2 = 450
450 + 9700 = 10,150 pounds
b. Flaps 40%:
11,380 - 9000 = 2380
2380 ÷ 2 = 1190
1190 + 9000 = 10,190 pounds
9. (Step 3 procedures): From the ACCELERATE-GO graphs, using 10,150
pounds for flaps at 0% and 10,190 pounds for flaps at 40%, the resulting
distances are within the available accelerate-go distance of 6786 feet.
a. 6050 feet with flaps at 0%
b. 5000 feet with flaps at 40%
10. (Step 5 procedures): Enter the TAKE-OFF FLIGHT PATH graph and adjust
the horizontal distance from Reference Zero and determine minimum
gradient of climb.
a. Flaps 0% - From Reference Zero (9486 - 6050) = 3436 feet
Minimum Gradient of Climb = 4.0%
b. Flaps 40% - From Reference Zero (9486 - 5000) = 4486 feet
Minimum Gradient of Climb = 3.1%
11. (Step 6 procedures): Enter the NET GRADIENT OF CLIMB - FLAPS 0%
graph at 10,150 pounds for a 4.7% net gradient of climb. Enter the NET
GRADIENT OF CLIMB - FLAPS 40% graph at 10,190 pounds for a 3.5%
net gradient of climb.
a. Since these results are greater than the minimum value, the take-off
weights of 10,150 pounds with flaps at 0% or 10,190 pounds with flaps
at 40% may be used.
b. If an exact value is required, complete the next step and repeat Steps 3,
5, 6, 7 and 8.
12. (Step 7 procedures): Enter in reverse the NET GRADIENT OF CLIMB -
FLAPS 0% graph using minimum gradient of climb of 4.0% for a take-off
weight of 10,800 pounds and the NET GRADIENT OF CLIMB - FLAPS 40%
graph using minimum gradient of climb of 3.1% for a take-off weight of
10,550 pounds.
