Honeywell Aerospace Laseref IV Upgrade

Although Honeywell Aerospace will plan to stop supporting legacy products Laseref II and III on December 31, 2019, Duncan Aviation customers who wish to upgrade to the Laseref IV are eligible for rebates and special pricing.

The Laseref IV IRU (Inertial Reference Unit) is an all-digital RLG (Ring Laser Gyro) that provides outputs for ARINC 429 and standard aircraft communication buses.

STCs (Supplemental Type Certificates) are available for the following makes and models:

  • Falcon 900EX, 900C, 900A/B, 2000, 2000EX
  • Challenger 600, 601
  • Global Express
  • Hawker 800, 800XP, 1000
  • Cessna Citation X

The Laseref IV is 35% lighter than previous versions, is interchangeable with the Laseref III (has an Adapter Tray available for Laseref II), and uses considerably less power than either previous version.

Duncan Aviation customers are invited to schedule their upgrades at any one of our 27 Satellite Avionics Shops or Workaway Stations.
