Been reading some of the posts here and like many, I wonder why the crews waited so long to divert based on min diversion fuel and no extra.
In present outfit, the diversion fuel is based on a cost index of 0 and not the normal 35 - which can be a bit of a gotcha, as your obviously going to burn a lot more than it says in the plan unless you change to cost index 0 for the diversion.
As the old saying goes ' you only have too much fuel - when your on fire ! '
