confused
Now I am a little confused. What are you trying to avoid by doing this? Adding alternate fuel for a 14 hrs flight so you could maximize pay load?
So a hkg-lhr sector becomes hkg-man (which I assume is severe clear) and then in the air the flight gets good TAF reports substantiated by good METARs and then plane asks to be headed to lhr now? Is that how it works?
What are your international fuel requirements except ofcourse for the TAXI and BURN(TRIP/MISSION/however you call it) fuels? (What kind of reserve, altn, extra, route reserve etc do you need to be taking)
Also for people from my side of the planet (i.e USA) - Do we do it here? Is it allowed with our heavys going abroad?
