Duncan Aviation Authorized to Modify Extended Life Battery

LINCOLN, NEB. — Duncan Aviation is now authorized to modify the UNS-1C Flight Management System (FMS) to include an extended life battery. The modification also comprises an adapter assembly and internal hardware modifications to accommodate the new battery.

"The main advantage is longer life and when the user gets a 'low battery' warning, they have three months to get the battery replaced before they lose any pertinent information," explains Don Fiedler, OEM Program Manager at Duncan Aviation's Lincoln, Neb., location.

Previously, only Universal Avionics Systems Corporation (UASC) was able to complete this modification. Duncan Aviation is the only other avionics service provider in the United States with the authorization to complete this modification and our team members have executed more than 50 in the first two months of the program.
