Final Reserve Fuel
Hi,
I'm looking for additional information/background on different final reserve fuel requirements for domestic vs. international flights in the FAA world (or elsewhere if anyone should be aware...)
Fact check first - my understanding is for FAA, turbo powered aircraft, part 121:
fuel for 30 minutes @ 1.500 feet, holding fuel flow (International)
fuel for 45 minutes @ normal cruise consumption (domestic)
My questions are:
1. Is this correct at all, or did I miss / misunderstand something here?
2. What is the ratio behind it? Coming from the European world, I have a hard time to understand why the final reserve fuel requirements for the same airport and aircraft should differ when you took off on this or the other side of the border...?
3. Are there similar rules imposed by other CAAs?
Thanks!
PS: I had posted a similar question in an other forum, but I think this one is more appropriate... Blame it on my lacking exerience...
