Reserve Fuel for a 9000km trip
Guys, How much trip fuel and reserve fuel should I load for a 9,000 km (4,900 nm) trip. Let's say my aircraft MTOW is around 230,000 kg (507,000 lb) . FL350.
After doing some maths I've estimated:
75,000 kg (165,300 lb) for Trip Fuel
10,800 kg (23,800 lb) for Reserve Fuel (10% time trip + 30 minutes holding at 1500ft at alternative airport)
So Total Fuel Weight = 85,800 kg (189,000 lb)
What do you think guys? Is this an accurate estimation?
