FL255 Five Tank Fuel Level Instrument The FL255 instrument is an advanced, next generation airborne fuel level reporting instrument that supports five fuel tanks, 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 each tank
• Selectable digital fuel quantity for each tank
• Fully programmable color indication to meet all aircraft marking requirements
• Graphical fuel level indication, starting at power on

The FL255 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 FL255 instrument utilizes the existing fuel senders.
