An aircraft has a mass of 5000 lbs and cg located at 80 inches aft of datum the aft cg limit at 80 5 inches aft of datum what the maximum mass that can be loaded into a hold situated 150 inches aft of datum without exceeding limit 35.97 lbs, 58. 5 lbs, 39.5lbs, 23. 5 lbs. Mass added / old total mass = change of cg / distance from hold to new cg mass added = (change of cg / distance from hold to new cg) x old total mass mass added = (0.5 / (150 80.5)) x 5000 mass added = 35.97 lbs. Question Cargo Handling 72 Answer 32
An aircraft has a loaded mass of 5500 lbs the cg 22 inches aft of datum a passenger mass 150 lbs moves aft from row 1 to row 3 a distance of 70 inches what will be new position of cg assuming all dimensions aft of datum 23.9 inches, 2.inches, 26.3 inches, 22.9 inches. Mass moved / total mass = change of cg / distance moved change of cg = mass moved x distance moved / total mass change of cg = 150 x 70 / 5500 = 1.9 inches new cg location 22 + 1.9 = 23.9 inches. Question Cargo Handling 72 Answer 33
The cg limits of an aircraft are from 83 inches to 93 inches aft of datum the cg as loaded found to be at 81 inches aft of datum the loaded mass 3240 lbs how much mass must be moved from forward hold 25 inches aft of datum to aft hold 142 inches aft of datum to bring cg onto forward limit 55.38 lbs, 74.96 lbs, 82. 9 lbs, 22.49 lbs. Mass moved / total mass = change of cg / distance moved mass moved = (change of cg x total mass) / distance moved mass moved = (2 x 3240) / (142 25) mass moved = 55.38 lbs. Question Cargo Handling 72 Answer 34
An aircraft has three holds situated 10 inches 100 inches and 250 inches aft of datum identified as holds a b and c respectively the total aircraft mass 3500 kg and cg 70 inches aft of datum the cg limits are from 40 inches to 70 inches aft of datum how much load must be removed from hold c to ensure that cg positioned on forward limit 5 kg, 25kg, 4 kg, 35kg. Mass change / total mass = change of cg / total distance moved mass change = change of cg x total mass / total distance moved mass change = ((70 40) x 3500 / (250 40) mass change = 30 x 3500 / 210 mass change = 500 kg.
