So to summarise:
Qantas does not plan an alternate on a nice weather day.
Qantas does plan a Tempo fuel for any WX below alternate criteria ( or an alternate) so covered for any bad WX.
Qantas also adds extra fuel to plans varying on type, eg A330 plans to min 5 ton overhead regardless.
Qantas also adds extra fuel depending on depressurisation points etc.
Some airlines plan alternates regardless of any of above but may end up with less fuel than average Qantas flight?
Also pilots simply add fuel to the figure they want without anyone from management bitching.
I personally put alternate fuel on to cover another aircraft fing up if there is only one runway.
It is Qantas that needs to change?
