Then Question 44: “You have 2,500 kg of fuel. Trip fuel 1,800 kg. Alternate fuel 400 kg. Final reserve 300 kg. Extra fuel 0. Is this legal for IFR?” Leo quickly added: 1,800+400+300 = 2,500. Exactly. Legal. He almost ticked “Yes.” But then he remembered: final reserve is for holding at alternate after missed approach. But the regulation says: you need trip + alternate + final reserve + any contingency (5% of trip or 5 min hold). He had not added contingency. Oh no.
