  • Flight planning new question

    Hello,

    can anybody help me understand how to solve this question?
    It's one of the new ones in the Flight Planning Exam. Apparently, it came up for everybody.


    A VFR flight is planned from departure aerodrome A to destination B with alternate C via a PDP:

    AB 530 NM
    AB 480 NM in cruise
    AC 495 NM

    Fuel flow is 35l per hour
    TAS 120kts
    Tail wind is 15 knots

    How much additional fuel is required?


    I can't really understand what they're asking for with "ADDITIONAL FUEL". Any help is appreciated.

    Thanks!

    Hi Marco

    I believe we met at Gatwick last week, my belief is this the info we had was only enough for the additional fuel and it referred for a reciprocating engine is 45 mins + 15% of enroute distance thus 380/tas x ff followed by x 15% then work out 45mins at tas added together then work out 2 hours of fuel flow compare choose the least and voala... if you get the Turbine version simple ff x2 hours

    remember this is based on this question and the amount of info that was in the exam

    good luck amigo I hope this helps
    ciao

      Hi Marco
      Have a look at QID 330759 in the bank. Tom has shown the working and included a paste of the relevant regulation.

        Hello!!!
        Thank you so much for your explanation, it really helped.
        What really threw me off is the "PDP" in the question. It made me think they're asking for contingency but in fact it's simply an "additional fuel" question. Isn't it?

        I worked it out this way:
        1) Tas=120Kt + 15Kt TAILWIND ----> GS= 135Kt
        2) fuel for 45 min --> 26,3 l
        3) fuel covering 15% @crz --> 18,7 l
        4) additional fuel --> 26,3l + 18,7l = 45l

        Would you say this is correct?

        @ JJ Jones
        QID 330759 doesn't seem to exist in the bank..


        One more new question I had in the exam which I found difficult (I'm sure of the question but unsure of the possible answers)

        E(HI)1

                  Hi JJ

                  would you consider this as correct answer for the question above?


                  1) Tas=120Kt + 15Kt TAILWIND ----> GS= 135Kt
                  2) fuel for 45 min --> 26,3 l
                  3) fuel covering 15% @crz --> 18,7 l
                  4) additional fuel --> 26,3l + 18,7l = 45l
