Question 82-1 : Given zero fuel mass 4770 kgtrip fuel 1040 kgblock fuel 1960 kgtaxi fuel 20 kgthe actual take off mass is equal to ? [ Attainment AIM ]

Question 82-2 : Considering only structural limitations on very short legs with minimum take off fuel the traffic load is normally limited by ?

Maximum zero fuel mass.

Maximum zero fuel mass exists to prevent wing bending if too much weight is concentrated in the fuselage then the wings will flex dramatically in flight by placing fuel into the wings the weight is distributed more evenly there is not a concentration of mass in one areaon very short legs with minimum take off fuel it means very low fuel in the wings and no fuel in center tank the traffic load will be limited due to this bending moment at the wing roots

Question 82-8 : To calculate the allowable take off mass the factors to be taken into account include ?

Maximum landing mass augmented by the fuel burn.

Maximum landing mass and the trip fuel correct because you can take off at the mlm plus trip fuel because you would land at mlm in the mlm would be the reserve contingency and diversion fuelmaximum take off mass minus the trip fuel this is nonsense the mtom minus trip fuel will not give the allowable tom maximum landing mass and the fuel on board at take off it can't be the mlm plus take off fuel because this would mean you would land above the mlm as you would only plan to burn the trip fuel thus you would be landing at mlm plus reserve contingency and diversion fuelmaximum zero fuel mass and the trip fuel this cannot be right because the allowable tom is not the mzfm plus trip fuel but the mzfm plus take off fuel assuming it doesn't exceed the mtom
