Over the years, Hornets have experienced various difficulties with their engines, fuel systems and fuel displays. One example found in most, if not all, of the air forces operating the F/A-18, has been a recurring engine fire problem. Strongly suspect is these fires is the fuel recirculation system, which cools the AMAD (Airframe Mounted Accessory Drive,the motive flow pump power source) and the hydraulic 1 and 2 oil.

Another aggravation concerns the cockpit fuel display, which alerts the pilot to fuel consumption rates, bingo and other related data. "Bingo" refers to a minimum fuel for a comfortable and safe return to base. Aircraft can fly and fight past bingo fuel in combat situations, but at considerable peril. Aviators typically set an initial bingo value higher than required by the actual task for just this reason. When the "Bitchin' Betty" aural warning announces "Bingo, Bingo", the pilot re-sets a "real bingo" accordingly, realizing he'll soon be turning for home.
