---whilst the intent of that 'arrive with fixed-reserve fuel' section is laudable
Biggles,
Let me make it a bit clearer ----
you should have 30 minutes fuel in the tanks at the end of the landing roll.
All other "reserves", weather, holding, ATC, approach allowance or however you calculate it is on top of the 30 minutes fixed final reserve. Normally the 30 minutes is calculated at the holding fuel flow for the landing weight.
Its all about making certain you have at least some fuel in the tanks at the end of the flight --- have a look at the ATSB/BASI records over the years. One would have thought "training and education" should be enough, but the record seems to indicate otherwise.
Lets be clear, it not laudable, its the law --- already, has been for years---- for most heavy aircraft, and will now apply to all operations --- better get used to the idea.
Tootle pip!!
