Diagnostic Fuel Management Controller ׂ(DFMC)

The Diagnostic Fuel Management Controller is an advanced fuel quantity
measurement & management controller with enhanced monitoring capabilities, specifically designed to provide real-time indication to the pilot of trapped fuel or fuel-related imbalance, as well as providing the maintenance personnel with full diagnostic and analysis capabilities regarding such occurrences.
The controller is currently in service with the F-16 fleets of several Air Forces and can be installed on any F-16 aircraft by a simple and quick retrofit.

 Benefits

• Improves flight safety by providing real-time in-flight warnings of:
  •  Trapped fuel
  • Fuel leaks
  • Fuel transfer failures
  • Fuel imbalance
• Reduces pilot workload on fuel system in-flight monitoring
• Improves mission reliability - less flight aborts
• Reduces fuel system maintenance costs through accurate diagnostics
• Shorter AOG through simple fuel system troubleshooting process

Main Features

• Measures and monitors all fuel tanks (both internal & external)
• Controls the fuel quantity indicators
• Provides fuel quantity data to the aircraft computer and to the fuel imbalance controller
• Detects and displays failures – trapped fuel, imbalance, sensors failures
• Records fuel system related events and commands
• Continuous in-flight fuel system behavior recording
  • Throughout each sortie
  • Individual tanks fuel quantity measurement and recording
  • Continuous calculation, recording and comparison of fuel transfer rate to the desired one
• Simple unit retrofit at the flight line level
• Compatible with all F-16 Blocks
