Honeywell Phases In Laseref IV Upgrade

Operators of several major business jet types will soon have an excellent opportunity to replace outdated Laseref® II and III navigation systems with the Laseref IV all-digital ring laser gyro based inertial reference system.

This is significant because Honeywell will soon be ending aftermarket product support for its Laseref II and III systems, both of which have been out of production for several years.

Aircraft eligible for the Laseref IV upgrade include:

  • BAe Hawker 800, 800XP (BAe 125)
  • BAe Hawker 1000
  • Bombardier® Challenger 600 series (600, 601-3A/-3R)        
  • Bombardier® Global Express
  • Cessna Citation X
  • Dassault® Falcon 900A/B/C/EX
  • Gulfstream® G-IV and G-V

“It’s a simple unit replacement that brings immediate benefits,” said Frank Hefner, Senior Program Manager for Honeywell’s BGA aftermarket team. “In addition to long-term product support, operators upgrading to the Laseref IV can look forward to lower weight and even better reliability.”

Honeywell estimates that, depending on the platform, aircraft weight will be reduced by 25 to 75 pounds and mean time between failures (MTBF) will show a 30 percent increase with the Laseref IV’s demonstrated 30,000 hours.

Pricing for the replacement will be announced in a sale bulletin in the near future.

The Laseref IV is the fourth generation ring laser gyro-based inertial reference unit, providing Honeywell’s proven laser inertial technology in the lightest 4 MCU rack-mountable package.
