A jet airliner aircraft is flying with crew load of 150kg, payload of 520lb and fuel weight of 500lb. Find out the empty weight if design take-off gross weight of the aircraft is given 1525lb.

A jet airliner aircraft is flying with crew load of 150kg, payload of 520lb and fuel weight of 500lb. Find out the empty weight if design take-off gross weight of the aircraft is given 1525lb. Correct Answer 79kg

Given, Design take-off gross weight, W0 = 1525lb Crew load = 150kg = 150*2.205lb = 330.693lb Payload weight = 520lb, fuel weight = 500lb Now the design take – off gross weight is given by, W0 = Wcrew + Wpayload + Wfuel + Wempty 1525 = 330.693 + 520 + 500 + Wempty So, Wempty = 174.307lb = 79 kg.
