- correct answer the CG moves forward approximately 3 inches (refer to figures 32 and 33) what effect does a 35-gallon fuel burn (main tanks) have on the weight and balance if the airplane weighed 2,890 pounds and the MOM/100 was 2,452 at takeoff? - correct answer weight is reduced by 210 pounds and the CG is aft of limits (refer to figure 42) what effect does adding a 185-pound passenger have on the CG, if prior to boarding the passenger, the helicopter weighed 1,380 pounds and the moment is 136,647.5 pound-inches? - correct answer the CG is moved forward 1.78 inches (refer to figure 44 and 45) what is the new CG of a gyroplane after a 10-gallon fuel burn if the original weight was 1,450 pounds and the MOM/1000 was 108 pound-inches? - correct answer out of limits forward (refer to figure 53) how is the CG affected if radio and oxygen equipment weighing 35 pounds is added at station 43.8? the glider weighs 945 pounds with a moment of 78,000.2 pounds-inches prior to adding the equipment? - correct answer CG shifts forward 1.38 inches -- within limits (refer to figure 53) what is the CG of the glider if the pilot and passenger each weigh 215 pounds? - correct answer 81.08 inches aft of datum -- within limits what constitutes the payload of a balloon? - correct answer total weight of passengers, cargo, and fuel (refer to figure 56) the gross weight of the balloon is 1,350 pounds and the outside air temperature (OAT) is +51°F. the maximum height would be - correct answer 10,000 feet )refer to figure 56) the gross weight of the balloon is 1,200 pounds and the maximum height the pilot needs to attain is 5,000 feet. the maximum temperature to achieve this performance is - correct answer +97°F (refer to figure 57) determine the maximum payload for a balloon flying at 2,500 feet at an ambient temperature of 91°F - correct answer 505 pounds (refer to figure 57) determine the maximum weight allowable for pilot and passenger for a flight at approximately 1,000 feet with a temperature of 68°F. launch with 20 gallons of propane - correct answer 620 pounds (refer to figure 57) what is the maximum weight allowed for pilot and passengers for a flight at 5,000 feet with a standard temperature? launch with 20 gallons of propane - correct answer 670 pounds problems caused by overloading an airplane include - correct answer reduced climb rate, excessive structural loads, and shortened cruising range most aircraft are so designed that if all seats are occupied, all baggage allowed by the baggage compartment structure is carried, and all the fuel tanks are full, the aircraft will be - correct answer grossly overloaded when operating an aircraft, the pilot in command is responsible for using - correct answer the most current weight and balance data if the outside air temperature at a given altitude is warmer than standard, the density altitude is - correct answer higher than pressure altitude (refer to figure 8) determine the pressure altitude at an airport that is 3,563 feet MSL, with an altimeter setting of 29.96 - correct answer 3,527 feet MSL (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 - correct answer 1,700 foot decrease what are the standard temperature and pressure values for sea level? - correct answer 15°C and 29.92" Hg which factor would tend to increase the density altitude at a given airport? - correct answer an increase in ambient temperature which combination of atmospheric conditions will reduce aircraft takeoff and climb performance? - correct answer high temperature, high relative humidity, and high density altitude what effect does high density altitude have on aircraft performance? - correct answer it reduces climb performance (refer to figure 8) what is the effect of a temperature increase from 25 to 50° on the density altitude if the pressure altitude remains at 5,000 feet? - correct answer 1,650-foot increase (refer to figure 6) determine the pressure altitude with an indicated altitude of 1,380 feet MSL, with an altimeter setting of 28.22 at standard temperature - correct answer 2,991 feet MSL (refer to figure 8) what is the effect of a temperature increase from 35 to 50°F on the density altitude if the pressure altitud remains at 3,500 feet MSL? - correct answer 1,000 foot increase (refer to figure 8) what is the effect of a temperature increase from 30 to 50°F on the density altitude of the pressure altitude remains at 3,000 feet MSL? - correct answer 1,300 foot increase (refer to figure 8) determine the pressure altitude at an airport that is 1,386 feet MSL with an altimeter setting of 29.97 - correct answer 1,341 feet MSL what effect, if any, does high humidity have on aircraft performance? - correct answer it decreases performance what effect ford high density altitude, as compare to low density altitude, have on propeller efficiency and why? - correct answer efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes (refer to figure 39) determine the total takeoff distance required for a gyroplane to clear a 50-foot obstacle if the temperature is 95°F and the pressure altitude is 1,700 feet - correct answer 2,030 feet
