    Good afternoon all,

    Given the following data, what is the trip fuel required for a flight planned under the reduced contingency fuel (RCF) planning procedure?
    (A = departure aerodrome, B = commercial destination, C = optional refuel destination)

    A

    Original message missing for some reason, BGS instructors I applied a 5% RCF to the fuel required DP-B is this incorrect? Thanks.

      Sorry for the delay. You are correct! The RCF procedure requires the fuel to be calculated in 2 different ways, you must take the higher of the 2 calculations, which is just about guaranteed to be Calculation 1, which is

      The sum of:
      (i) taxi fuel;
      (ii) trip fuel to the destination 1 aerodrome, via the decision point;
      (iii) contingency fuel equal to not less than 5 % of the estimated fuel consumption from
      the decision point to the destination 1 aerodrome;

      (iv) alternate fuel or no alternate fuel if the decision point is at less than 6 hours from the
      destination 1 aerodrome and the requirements of CAT.OP.MPA.180(b)(2), are
      fulfilled;
      (v) final reserve fuel;
      (vi) additional fuel; and
      (vii) extra fuel if required by the commander.

        So the answer and explanation provided in the QB is wrong then? They only show trip fuel. No contingency, neither regular or RCF.

          Hi
          The question only asks for the trip fuel. The answer is therefore the trip fuel from the higher of the two calculations that must be compared. In this case the larger total fuel is from Calculation 1 so we take the trip fuel from that.
          Hope this helps
