FOB
Fuel On Board. FOB means Fuel On Board and refers to the quantity of fuel currently carried by the aircraft.
Expanded explanation
FOB is a good example of phrase-to-abbreviation intent
FOB sits in flight-operations and planning contexts where people often search the full phrase rather than the abbreviation. That makes it useful as a demo term because the search can resolve “fuel on board” into a short canonical slug without ambiguity.
Why it matters
FOB shows how glossary pages can capture awareness traffic and still support higher-value operational learning pathways later, without turning every term page into a sales landing page.
