Honeywell Aerospace Laseref IV Upgrade

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. In addition to the obsolescence of the previous IRUs, the LASEREF IV weighs 35% less than previous versions, and it’s interchangeable with the LASEREF III with an adapter tray, so there are no modifications necessary. Even better, the LASEREF IV uses considerably less power than the previous versions.

It automatically realigns functions after flights, preventing delays on quick turns, and automatically calibrates its sensors. Interfacing with the Honeywell HG2021 GNSSU ARINC 743A receiver gives pilots access to optimal GPS/Inertial hybrid computations.

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
