First of all, I don't
like these questions, and you are most unlikely to see them in the UK exam
system ..... however, for other nationalities, a definite
may be ...
Sector time =
(Climb adjustment) 3mins + 2hrs 37mins + (descent adjustment) 10 = 2hrs 50mins,
or 2.833hrs
Fuel flow at cruise
(5000ft, ISA, 2300RPM) = (69.4+71.1)/2 = 70.55 PPH
Sector fuel =
(climb adjustment) 6 + (2.833 x 70.55) + (descent adjustment) 0 = 6 + 200 + 0 =
206 lbs
So, Ramp fuel =
TAXY + TRIP + RESERVE (30% of TRIP) = 10 + 206 + (30/100) x 206 = 278 lbs
There are about 3
of these in the databank ..... once
you understand what they are doing, its sort of OK!!
