The fuel tank inerting controller monitors and controls the fuel tank inerting system (FTIS). The FTIS provides protection against fuel tank fire and explosion by creating inert conditions within the ullage space of the fuel tanks. Pressure, oxygen, and temperature data acquired via analog sensors are used by the controller to support the distribution of nitrogen enriched air (NEA) into the fuel tank ullage.
The fuel tank inerting controller provides automatic control of the FTIS without pilot interaction. It has the ability to open/close the fuel inerting shutoff valves to control the flow of NEA into the fuel tanks. Fundamental features of the fuel tank inerting controller include the following:
? Provides over-temperature protection
? Monitors the oxygen concentration to insure the health of air separation modules
? Controls the temperature control valve and ground cooling fan to provide temperature controlled bleed air for inerting
? Microprocessor-based design
? System fault and health monitoring trend recording in NVM
? Software development according to RTCA-DO 178B and DAL Criticality Level B
