BACK TO THE PAST
Apologies for a slight thread drift and an admission that I've little to do with the CASA Part 91 as we have adopted the NZ rules here in paradise.
Way back when (note the aircraft type for a temporal reference) I was a newly minted controller I had an F4 call me at Amberley, "Amberley ground, Buckshot 28 taxi one for Willy, minimum fuel."
Bit of discussion in the tower with SATCO present and eventually I was tasked with providing a brief on the issue at the following day's mass morning brief -as we did in those days.
The pilot made the correct call, given the forecasts, a couple of NOTAMs and fuel carriage.

P. S. Grew up in aviation from 1968 with the Australian legislation and had a year "regulating" the AIP but having worked with them now for a couple of years and recently had need to compare some parts with the CASA views and attitude - NZ gets my vote.
