Hi Derfred,
I was under the impression that there was some aircraft design rule that engines must still be turning as fuel gauges click to zero. I would really like to know whether my engines will actually keep turning for those 30 minutes.
Correct.
All manufacturers of commercial aircraft have to establish useable & unuseable fuel. The unuseable fuel is included in the dry operating weight.
"Fuel quantity indications
The primary function of the system(s) is providing usable fuel quantity indications. This includes the total usable fuel quantity which shall be permanently displayed and be easily and directly readable by the pilots; indeed, this is considered as essential information which shall be regularly checked by the pilots per operational regulation. The usable quantities of each individual tank must be available as well but it is acceptable that they are displayed only when required (on demand or automatically)."

piratepete,
I shut down one engine on touchdown, no reverse on the other donk, no APU until at the gate etc etc......
You made far more work for yourself than necessary. It's the remaining fuel on Landing that was important - not at the gate.
