When adding in NAIFR fuel to SimBrief, it is showing up below-the-line and therefore not as protected fuel. Would it be possible to change NAIFR fuel to show up above-the-line?
I cannot speak to other OFP formats, but on the United OFPs, as a FAR reserve, NAIFR fuel would show up in the FAR category on the UAL 2018 format OFP (above-the-line).
On the UAL 2018 format, it should be labeled FAR on the OFP according to the Flight Manual. Cannot speak for the other formats. My FM is not the most current, but it is from after the SABRE transition.
