If you take too much fuel do you get a phone call? Or Email? Ie- please explain why you have costed us more etc...
There are legal implications to such behaviour. For instance, replying that you'd be happy to come and see them, but will be bringing along a representative from CASA would have them suddenly lose interest in seeing you.
But presumably the net result is neutral?
If 'too much' were taken on for a flight, and not fully used, then the flight that followed would not need as much - even if the Captain was ultra-cautious. Of course, I guess the price at different locations may impact on the bean counters' view of things.
No. There is a cost of carriage. In very rough figures, you'll burn any additional fuel in 24 hours. So, a 12 hour flight would burn about half of any extra. A one hour domestic would use about 5% of it.
Yes that’s true. But we’re not talking about ridiculous extra amounts of fuel. I like to carry an extra 30mins on a good day depending on the location which is about 1 tonne of fuel extra. To carry that fuel to the destination would only require a burn of about 50 - 75kg.
The bean counters do cringe a lot including trying out single engine taxi into the bay and not turning on the APU so early, or at all if ground power is available once we’ve chocked
.
The counters of beans assume that things would have gone their way, if you hadn't carried extra. So, it you put some on because you were concerned about the possibility of a diversion going in to Dubai, and that extra wasn't actually burnt, but its mere presence allowed you to continue, then they would have no idea of that outcome, and would simply assume that their lower figure would have been okay too.
They also never think things all the way through. For instance, once you have diverted, you generally go to the bottom of the priority list. So, it may not be a splash and dash, but in the worst case could mean finding another crew and flying them in to the diversion field. My job was to make problems go away, not to invite them.
Mind you, it was a good laugh, when sitting in the holding pattern (at Dubai), one of the zero extra fuel men arrived, and he couldn't cover the holding and had to immediately divert. We held, then landed at destination. The other aircraft was still on the ground at the diversion field when I was up to my second beer.
