ASL SINGLE TANK FUEL LEVEL - RESISTIVE SENDER

FL201 Single Tank Fuel Level Instrument

The FL201 instrument is an advanced, next generation airborne fuel level reporting instrument that supports two fuel tanks.

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 FL201 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 FL201 instrument utilizes the existing fuel senders.
