LINCOLN, NEB — With 9 weeks remaining until the FAA’s mandate deadline for aircraft to upgrade to Automatic Dependent Surveillance-Broadcast (ADS-B), Duncan Aviation Satellite Avionics Manager Bill Gunter in Oxford, Connecticut, has also noticed a shift away from ADS-B to other upgrades to other avionics equipment. 

Most customers in the Oxford area have already upgraded, and Gunter has only one more ADS-B upgrade scheduled before the January 1, 2020, deadline. Instead, he’s been fielding questions and preparing quotes for equipment that’s facing obsolescence.

“Some of our Gulfstream IV customers are asking us about the Honeywell Service Bulletin for the Honeywell Laseref, the Inertial Reference Unit (IRU) system,” says Gunter. “They’re interested in upgrading to the Laseref IV because the previous versions are facing obsolescence.”

Duncan Aviation Regional Avionics Manager Michael Kussatz for the East Coast of the United States knows there are still hundreds of aircraft  throughout the United States that need to be upgraded to ADS-B, but he’s also seen a similar shift in quote requests.

“Customers who have already brought their aircraft into compliance with the ADS-B mandate are requesting quotes for connectivity, such as the Gogo AVANCE L5 and L3,” says Kussatz. “We’re also encouraging customers who are dealing with the obsolescence of their Honeywell Laseref II or III to take advantage of the financial incentives Honeywell is offering on upgrades to the Laseref IV, now through the end of 2019.”

Regardless of whether you’re replacing obsolete equipment, installing new, or upgrading existing to bring it into compliance, Gunter and the other three avionics technicians at the Oxford Satellite go to customers’ hangars to perform the necessary work.

“We recently completed ADS-B installations for a fleet of Pilatus PC 12s for a customer, using the Garmin STC,” says Bill. “Because we’d done so many of them, we were able to turn them in as little as five days. We went to our customer’s hangar while each aircraft was down for maintenance, so it was pretty easy and convenient for everyone involved.”

Whether you’re looking for connectivity options, have questions about the financial breaks available when you upgrade to the Honeywell Laseref IV, or are seeking available space for an ADS-B upgrade at a Duncan Aviation Satellite Avionics Shop or workaway station, please contact:
