Intresting subject. Let's say I know of a company not run by beancounters yet (some will argue it is not run yet at all) where no justifications need to be made and at present probably noone thoroughly analyses fuel uplift data.
It is a single hub (two intersecting runways) s/h operation, main alternate is 1000 - 1400 kg away wind/weight dependent, company standard final reserve is planned at 1250 kg fixed, speaking of 737-4/5 operations. Vast majority of pilots decide to take no less than 1200 extra for "half an hour" irrespective of weather, thus the landing fuel stands at 4000+ kg, that is the figure aimed for. Altough perhaps unnecessary on many occasions, I agree it keeps the strain out of the brain.
Once I spoke to a fellow countryman who earns his € refuelling at Frankfurt, if he is to believe we arrive with close to most fuel, outtankering our competitors by average 2000 kg. That being said, FRA is 45 min tkof/ldg and we tanker fuel OUT of there. It is nice to know that if doomsday came we could turn back, fly home, and on minimum reserves reach the 3rd farthest alternate (1300-1700kg), but...
... my question is, would this be tolerated in "properly" run "western" company?
