Fuel Management Questions - various strategies

[n86121]

This graph shows the tanks volumes and switchover points.

I assume like a 210 that even though I fill the tanks, they may not be 100% full.

The shadin is set to flash 'low fuel' once 76 gals used, i.e. 16 in mains and 36 in aux

Then burn down 28 of the aux, leaving 8 in the aux just in case.

The shadin also flashes with 40 minutes left, to remind me to go back to mains.

Then switch back to the main for landing, etc.

The 8 in the aux just in case.
