PERFORMANCE
Wind = 210

at 17 knots. Determine headwind
component from Figure 5-9. (16 knots
headwind))
Enter Figure 5-25
at 6000 pounds; the approach speed is 88 KIAS.
Proceed horizontally right from 2000 foot pressure altitude to the
vertical column for 10
0
C (500F). The landing distance ground roll
is 840 feet and the total distance required to clear a 50-foot
obstacle
is 2270 feet without wind correction. With a 16-knot head-
wind component, the corrected ground roll distance is 759 feet and
the corrected total distance required is 2052 feet.

Rate-Ol-Climb - Balked Landing Climb (Figu,e 5-16)
(1) Enter Figure 5-16 at 7°e (45°F).
(2)
Proceed vertically up to the 1700-foot pressure altitude line.
(3) Proceed horizontally right to the weight reference line.
Follow the guidelines up and to the right until intersecting the
vertical 5572-pound weight line.
(4) Proceed horizontally right to determine the rate-of-climb.

Total
Fuel Required
= Start, taxi and climb fuel + cruise fuel

= 64 pounds + 552 pounds + 47 pounds = 662
pounds (Without Holding Fuel)
or 662 pounds + 103 pounds = 765 pounds
(With 45 Minutes Holding Fuel)
