Question 1 50 points A jet transport has the following properties and mission specification: Payload: 120 passengers at 80 kg each and 25 kg of baggage each. Crew: Two pilots and 5 cabin attendants at 80 kg each and 15 kg of baggage each. Range: 2,970 km. Reserve for flight to an alternate airport 200 km away followed by 29 min loiter. Altitude: 10,650 m. Flight to alternate is at an altitude airport of 5,500 m at. Time to climb: 15 mins. Cruise speed: M = 0.84. Power plants: Two low-bypass turbojet engines. Configuration: Low-wing, two slotted fowler flap. You may assume that: Stall velocity, Vs = 211 ft/sec. Maximum L/Dis 19 (L/D for flight to alternate is 12). SFC for flight to alternate is the same as during loiter. PART A-WEIGHT CALCULATION Calculate the following aircraft weights: Jet transport take-off weight [15 marks]. Number Units Jet transport empty weight [5 marks]. Number Units Jet transport fuel weight [5 marks]. Number Units PART B-SENSITIVITY ANALYSIS Calculate the jet aircraft take-off weight's sensitivity to the following parameters: OWTO Payload weight [5 marks] aw PL Number OW TO Empty weight aw [5 marks) E Number OW TO Range (disregard flight to alternate) [5 marks]. ar Number Units BWTO Endurance E [5 marks].
