Bingo Fuel State Alert for F-5 Aircraft

The Naval Air Systems Command (NAVAIR), PMA-226 Adversary and Specialized Aircraft, Integrated Product Team (IPT), is considering procurement of a system or instrument which allows aircrew to configure custom total fuel level alerts (also known as “Bingo” or “Joker” fuel bugs) for use on single-seat F-5N and dual-seat F-5F aircraft. The fuel level is monitored through capacitance signals sent from two fuel probes and displayed with dual pointers (left and right) in increments of 100lbs, ranging from 0 to 2,500 lbs. If carried, external fuel tanks are pumped to internal tanks and represented through the right pointer. This Bingo Fuel State Alert would allow for mission specific fuel level alerts to be entered during preflight and activated during flight. Currently the F-5 fuel system only has a low fuel light that activates when fuel level reaches 350-410lbs of fuel remaining which is an unsafe condition.
