Sasless;
Which brings up a question for the NPAS Pilots.
In your flight planning....do you start with a No Use Minimum Fuel Quantity that is in addition to the standard Reserve Fuel.....that being "Minimum In-Flight Fuel" at which point a Precautionary Landing becomes mandatory to prevent running out of Fuel while Airborne?
I think the answer to your question is that we have to be on the ground with a minimum of 60kg day / 90kg night. That's one figure called the 'Minimum Landing Allowance'.
(different operators may have different MLA's)
Whether that's in a field or at a refuel facility, simple
"'No Use Minimum Fuel Quantity', 'Standard Reserve Fuel', 'Minimum In-Flight Fuel'"
Whats all that about!
Why use one phrase when you can have three!
