Surely the KEY aspect here is not so much HOW MUCH extra you take
but more HOW LONG you carry it for!
In other words for a short haul pilot like moi......
If I take half a tonne extra- and my sector time is 65 mins- I'll have pretty much all of my 500kg extra when I get near the airfield-which I can then use to deal with whatever it was that I took it for.
Or land with it unburnt! And damn little of it wasted!
( I know it's a different arguament if you carry it for 13 hours- most of it is gone when you arrive- so why take it?)
For short haul- I'm unconvinced that carrying a bit extra is very wasteful.
btw I was on a UK flight that diverted due to not having 15 mins holding fuel 10 days ago. Wonder what that cost?
