Report 'Fuel Differences'
In a section OPS, tab Checklist you can input such Fuel details as:
BLOCK - the amount of fuel as has been consulted with CPT (not the BLOCK fuel planned by flight planning software).
BURN - the value calculated by flight planning software. This is the fuel which is burned in most cases, i.e. when the aircraft doesn't hold and doesn't divert to the alternate airport.
MRF - Minimum Fuel Required - minimum amount of fuel required for the trip (not included in this report).
With this report you can compare the planned fuel usage with the real Used fuel entered to the Journey Log.
