The Duncan Aviation /Garrett APU system interfaces with the aircraft’s electrical system and includes controls for operating, monitoring, and regulating the APU. As seldom as these systems fail, when they do, it can be confusing to determine which box is causing the problem.
As LITEF LCR-92/93 AHRS units become increasingly difficult and costly to support, legacy PC-12 operators need a practical way to address avionics obsolescence without a major flight deck upgrade. Archangel Systems’ FAA-approved replacement provides a current-generation solution designed to minimize installation time, aircraft modifications, and downtime.
Few business jets have had the staying power of the Dassault Falcon 900. More than 40 years after its first flight, the three-engine Falcon 900 remains a capable large-cabin business jet, thanks to decades of refinements to its engines, range, aerodynamics, and avionics. While the different 900 models may look similar on the ramp, their capabilities, maintenance needs, and market values can vary significantly. Understanding how each generation evolved—and what those changes mean for ownership—can help buyers make a more informed decision when considering a Falcon 900.

If you want to see an angry passenger, tell him or her you have Wi-Fi and then have it not work.
If you still use floppy disks to update your navigation databases and have a Honeywell DL-900 data loader, there are five very good reasons to look at upgrading to the DL-950 or DL-1000.
Two of Duncan Aviation’s Avionics Satellite shops have recently installed a serviceable Gogo ATG-5000 airborne broadband system with Wi-Fi, one in a Gulfstream IV and the other in a Gulfstream G-200.

Most Challenger operators are now well aware of the 2020 mandates for ADS-B transponder upgrades for both the U.S. and Europe. However, we find that many are not aware of the ADS-B standards, options, and prerequisites required.
