Sir at the back of the book the answer for question 10 is 21.25..but for me I got 25.25 which is C is the correct for me..
see my working:
Time= Dis÷Speed
155÷103= 90 minutes
Flight fuel= fuel flow × Time
11.5 × 90= 17.25 Gallons
F/Fuel= 17.25
No Variable
Fixed Res- 4
Taxi- 0
Holding- 4
FOB @ Start up= 25.25 Gallons
Please advice me if I made any mistake.
Answer should be "C" but at the back of the book is "A"
Which one is correct?
I think you must have an older book as that question has been updated that being said, your answer is correct
