Add Sophistication and Flexibility to Aircraft
Radio Control and Tuning Operations
Universal Avionics’ Radio Control Unit (RCU) provides a centralized, easyto-
use control interface, with radio tuning and mode control function.
Consolidating multiple radio control heads into a single, advanced controller
will provide savings in space and weight, while increasing efficiency
and adding sophisticated radio tuning capabilities to your flight deck.
Bezel-mounted controls provide quick and simple tuning of manual, prestored,
standby, previous, next, and suggested frequencies/ identifiers.
Eighteen pilot-selectable preset frequencies can be accommodated
for NAV, COM and ADF radios. You can conveniently tune any onside or
offside COM, NAV and ADF radios as needed. The RCU also includes a
unique guarded-keyed emergency function which automatically sets
the preset frequencies for the COM radio and transponder to 121.500
MHz and Code 7700 respectively. The option to enter an eight or ten
character flight ID is also available.
The RCU seamlessly integrates with Universal Avionics’ Flight Management
System (FMS), or can be integrated into your flight deck as a stand-alone
radio tuning device. When interfaced to the FMS, the FMS will function
as a backup tuning source, as well as providing the RCU with up to six
suggested frequencies based on the active flight plan (VHF COM, NAV
and ADF radios), which reduces pilot workload.
The RCU features a high resolution, color LCD display. An LED backlighting
feature adds higher reliability and lower power consumption, reducing
heat in the cockpit.
To support special missions operators, a Night Vision Goggle (NVG)-
compatible variant is also available.
