Contingency
fuel is 5% of TRIP = 290kg, no time is allocated.
290
kgs @ TRIP Fuel flow ( 2292 kgs / hr) = 7.6 mins
( 5800 / 2.530 = 2292 kgs /
hr)
Enter
the time for Final Reserve fuel for a jet, 30 mins
Insert

Add
the top line to find the
Minimum
T/O Fuel = 5800 + 290 + 1800
+ 1325 = 9215 kgs
Work
the actual T/O fuel back from the ramp fuel
Actual T/O Fuel = Ramp Fuel – Taxy Fuel = 9800 kg
Therefore
the “Extra Fuel” = 9800 -
9215 = 585 kgs
585
kgs @ the given 2400 kgs /
hr = 0.244 hrs = 14.6 mins

So, TOTAL ENDURANCE = 2:32 + 0:07.6 + 0:42
