Bingo Fuel State Alert for F-5 Aircraft N00421-26-RFPREQ-TPM226-0466
Summary
AI-generated · May 23, 2026Procurement of a system/instrument to allow aircrew to configure custom total fuel level alerts (Bingo/Joker fuel bugs) for single-seat F-5N and dual-seat F-5F aircraft. The system would read capacitance signals from two fuel probes and display on a dual-pointer gauge (left and right) in 0–2,500 lb increments of 100 lb; if external tanks are carried, they are pumped to internal tanks and shown on the right pointer. It would enable mission-specific fuel alerts to be entered preflight and activated during flight.
This capability is intended to replace the current setup, which uses only a low-fuel warning at about 350–410 lb remaining, a threshold considered unsafe. The requirement emphasizes compatibility with the existing fuel measurement approach, allowing configurable bingo thresholds to be entered before flight and engaged in flight for safer fuel management.
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.
