Chapter 8 aircraft performance
An aircraft is loaded 110 pounds over maximum certificated gross weight. If fuel
(gasoline) is drained to bring the aircraft weight within limits, how much fuel
should be drained?
18.4 gallons.
(Refer to Figure 8.) What is the effect of a temperature increase from 35 to 50°F
on the density altitude if the pressure altitude remains at 3,000 feet MSL?
1,000-foot increase.
(Refer to figure 61.) If 50 pounds of weight is located at point X and 100 pounds at
point Z, how much weight must be located at point Y to balance the plank?
300 pounds
(Refer to Figure 35.) Determine the approximate manifold pressure setting with
2,450 RPM to achieve 65 percent maximum continuous power at 6,500 feet with
a temperature of 36°F higher than standard.
21.0" Hg.
