Developed for airline or special mission operations, the MCDU features additional ARINC 429 I/O ports which can support up to six ARINC 739 interfaces for ACARS, Satcom and future NextGen CNS/ATM systems.

The MCDU interfaces with the UNS-1Fw and UNS-1Lw NCUs. It also includes an ARINC 702 bus for interface with third party FMSs.

FMS Flight Planning

FMS Flight Planning The Flight Planning (FPL) function provides you with the quickest, most efficient means of creating a flight plan, and the most pilot-friendly method of altering the flight plan elements as desired or required by ATC. It has been engineered to incorporate the greatest level of safety, with numerous built-in safeguards such as the entry of list-referenced selections which reduce both keystrokes and errors.

Fuel Management

Fuel ManagementUsing inputs from the fuel flow sensors, the MCDU displays extensive fuel information and calculations available – the kind that can eliminate unnecessary fuel stops, save you time and money and provide increased safety.


ListsThe unique LIST function provides a quick and efficient means to access and enter data, minimizing alphanumeric entries and reducing input errors.

Data Management

Navigation Data ManagementThe DATA function key provides access to a variety of navigation data management capabilities. Easy access to your stored navigation database for detailed review of SIDs, STARs, approaches, runways, airways, intersections, navaids and airports.


NavigationThe SBAS-FMS will fly all procedural leg types in accordance with ARINC 424. This sophisticated capability allows you to fly the most complex procedures such as heading to altitude, precision arc, procedure turn, holding pattern and more – all the necessary maneuvers required to accurately fly SIDs, STARs and approaches.


Dirct-ToThe Direct-To (DTO) function key is specifically dedicated for flight plan changes in response to “Direct-To” clearances. The SBAS-FMS easily takes you from your present position direct to any point on or off your flight plan using circular arc steering. If the desired waypoint is on the flight plan, it may be selected by entering its list reference number.

Vertical Navigation

Vertical NavigationVNAV provides for such features as computed Top-Of-Descent, Target Vertical Speed indication and selection, and Vertical Direct-To commands. Vertical waypoints can be conveniently defined with altitudes or Flight Levels, and lateral offsets.

Frequency Management

Frequency ManagementFrequency management capabilities allow you to tune your NAV and COMM radios through the FMS.


MessagesThe message key is used to access the system status advisories, including way- point alerts, sensor watchdog functions, TAWS alerts and self-test. “Pop-up” messages in response to invalid entries further simplify system operation. The Message (MSG) key may also be used to access datalink communications should this optional equipment be installed.

Night Vision Goggle-Compatible

Universal Avionics’ 4-inch and 5-inch FPCDUs are modified with Night Vision Goggle (NVG)- compatible glass display panels, which changes the lighting output in such a way that the unit can be used in flight decks where operators are wearing night vision goggles.
