Maintenance Panels

The fuel gauging system consists of seven active fuel probes located in each of the aircraft wing fuel tanks and a dual channel microprocessor-based Signal Conditioner. The signal conditioner processes the probe signals and computes the fuel quantity. A collector tank probe is typically used as a reference or compensator probe to account for changes in fuel density. Displayed, filtered, and unfiltered fuel weights are calculated and transmitted as ARINC 429 Outputs. Faults detected during Built in testing are recorded and transmitted.
