Lesson 9 Makeup Quiz

[3246] What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?

[3300] What effect, if any, does high humidity have on aircraft performance?

[3679]  (Refer to figure 35.)  What is the expected fuel consumption for a 1,000-nautical mile flight under the following conditions?

Pressure altitude          8,000 ft
Temperature                 22 °C
Manifold pressure       20.8″ Hg
Wind                               Calm

[3293] (Refer to figure 8.)  Determine the pressure altitude with an indicated altitude of 1,380 feet MSL with an altimeter setting of 28.22 at standard temperature.

[3299] (Refer to figure 8.)  What is the effect of a temperature decrease and a pressure altitude increase on the density altitude from 90 °F and 1,250 feet pressure altitude to 55 °F and 1,750 feet pressure altitude?

[3691] (Refer to figure 37.)  Determine the total distance required to land.
OAT                                     90°F
Pressure altitude              3,000 ft
Weight                                2,900 lb
Headwind component    10 kts
Obstacle                             50 ft

[3683, 8-42] (Refer to figure 36.)  What is the crosswind component for a landing on Runway 18 if the tower reports the wind as 220° at 30 knots?

[3686] (Refer to figure 36.)  With a reported wind of north at 20 knots, which runway (6, 29, or 32) is acceptable for use for an airplane with a 13-knot maximum crosswind component?

[3662] 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?

[3663-2] (Refer to figure 60.)  How should the 500-pound weight be shifted to balance the plank on the fulcrum?

[3664] Given the following conditions:
WEIGHT                  ARM          MOMENT
(LB)                       (IN)              (LB-IN)
Empty weight                   1,495.0                     101.4            151,593.0
Pilot and passengers          380.0                     64.0                   ——-
Fuel (30 gal usable
no reserve)                    —                       96.0                    ——-
The CG is located how far aft of datum?

[3675] (Refer to figures 32 and 33.)  Which action can adjust the airplane’s weight to maximum gross weight and the CG within limits for takeoff?
Front seat occupants     425 lb
Rear seat occupants     300 lb
Fuel, main tanks            44 gal
