  • Flight Planning Tankering - New question format

    Students can expect new questions, similar to the one below, in the exam. questions can be written to ask the maximum extra fuel or given a specific mass increase/decrease, what extra fuel is needed or what is the new burn off.


    Given the following information, in a Commercial Air Transport operation, calculate the maximum possible Extra Fuel, including any fuel penalty, that can be uplifted.

    MTOM: 230 000 kg MLM: 180 000 kg MZFM: 170 000 kg Planned ZFM: 156 000 kg

    Fuel tank capacity: 110 000 kg Trip Fuel: 40000 kg Planned T/O Fuel: 45000 kg

    Fuel burn correction per 1000 kg of Extra Fuel based upon: TOM: + 166 kg and LDM: + 199 k



    TOM: 156 000 + 45000 = 201 000 kg
    Extra based on MTOM: 230 000

    Sorry the system as chopped off the explanation or is that extra burn?

    Students can expect new questions, similar to the one below, in the exam. Questions can be written to ask the maximum extra fuel or, given a specific mass increase/decrease, what extra fuel is needed or what is the new burn off.


    Given the following information, in a Commercial Air Transport Operation, calculate the maximum possible Extra Fuel, including any fuel penalty, that can be uplifted.

    MTOM 230 000 kg MLM 180 000 kg MZFM 170 000 kg Planned ZFM 156 000 kg

    Fuel Tank Capacity 110 000 kg Trip Fuel 40 000 kg Planned T/O Fuel 45 000 kg

    Fuel Burn Correction per 1000 kg Based upon TOM + 166 Kg Based upon LDM + 199 Kg

    TOM 156 000 + 45 000 = 201 000 Kg
    Extra based upon MTOM 230 000 - 201 000 = 29 000 kg

    Fuel at Destination 45 000 - 40 000 = 5 000 Kg
    Extra based upon MLM 180 000 - 156 000 ZFM - 5 000 = 19 000 Kg

    To arrive at destination at the MLM would require an additional 19 000 / 1000 x 199 = 3 781 Kg Extra Fuel Burn

    Therefore the extra fuel that can be uploaded = 19 000 + 3 781 = 22 781 Kg

    Check against TOM 22 781 / 1000 x 166 = 3 781 Kg

    This is similar to the ratio method used in previous questions but as in all Questions only use the information given and do not mix methodologies or you will find different answers.

        I had this in Gatwick today. The numbers are almost identical to those posted by James in recent feedback. Rather than giving you TL and DOM, planned ZFM is given instead

        MTOM 875,000lb
        MLM 652,000lb
        MZFM 555,100lb
        PLANNED ZFM: cant remember
        Trip Fuel 198,620lb
        Planned T/O Fuel 226,195lb
        MAX tank capacity is 377,###

        Penalty per 1000lb extra fuel carried if based on TOM: +319.7lb, if based on LM: 470lb

        Find max additional fuel that can be carried

        3 marks, type in value to the nearest whole number

              Just got results, 100% in FP by some miracle, so this is confirmed now. Upload is based on MTOM limit which is 99490 or something similar if those numbers aren't exact. That was my last exam so good luck guys!
