When i do my flight plan I get an error that says my fuel is above the "block fuel" amount.  How do I correct this?

Meh. Somehow my answer got lost.

You do not have enough fuel for the aircraft and flight plan or the wrong aircraft performance loaded.

See here for all the details about perf in LNM: https://www.littlenavmap.org/manuals/littlenavmap/release/latest/en/AIRCRAFTPERF.html

You can download aircraft performance files here: https://www.littlenavmap.org/downloads/Aircraft Performance/

Or make your own: https://www.littlenavmap.org/manuals/littlenavmap/release/latest/en/TUTORIALPERF.html
