Key features & video overview
  • Form/Fit/Function Replacement — requires no aircraft modifications
  • Eliminates Cathode Ray Tube (CRT) and high-voltage power supply for improved reliability
  • Advanced Thomas ADA 2.0 display processing technology from Thomas Global Systems

Versatile and compact

The EFI-650 uses the latest-generation Active Matrix Liquid Crystal Display (AMLCD) technology and solid-state LED backlighting to eliminate the maintenance cost and obsolescence concerns associated with aging CRTs.

Reliable, lighter, less expensive

The EFI-650 displays provide higher reliability, reduced weight and lower life-cycle cost. The EFI-650 eliminates the outdated Cathode Ray Tube (CRT) display and its associated high-voltage power supply for improved reliability. The new design reduces display weight by 50 percent and provides a growth path for future enhancements such as Satellite-based Augmentation System (SBAS) approach, windshear annunciation and ADS-B In.
