FL251 Single Tank Fuel Level Instrument
The FL251 instrument is an advanced, next generation airborne fuel level reporting instrument that supports one fuel tank, used specifically with fuel senders that have a DC level output.
Fuel level functionality is TSO’d and meets the repeatable accuracy requirements of SAE AS405C, +/- 1US Gallon.
Functional displays include:
- Graphical indication of fuel level in the tank
- Digital fuel quantity for the tank
- Fully programmable color indication to meet all aircraft marking requirements
- Graphical fuel level indication, starting at power on
The FL251 instrument is TSO’d and STC’d as a primary replacement instrument under all flight conditions (day/night VFR and IFR). It is a requirement of the STC that this be the only fuel level indicator, when installed.
The FL251 instrument utilizes the existing fuel senders.
