Textron to offer Primus Epic upgrade for Hawker 4000 and Sovereign
FANS Controller Pilot Data Link Communication and Aeronautical Telecommunications Network Protected Mode CPDLC will replace the traditional voice communications on Hawker 4000 and Citation Sovereign aircraft.
The Citation Sovereign.

Textron Aviation and Honeywell Aerospace are developing an exclusive programme for Hawker 4000 and Cessna Citation Sovereign aircraft equipped with the Honeywell Primus Epic integrated cockpit to allow pilots to communicate more easily with air traffic controllers and utilise the most current data link services offered in North America and Europe. The aircraft upgrade is expected to be available in mid-2022.

Beechcraft, Cessna and Hawker customers receive factory-direct support, maintenance and modifications by Textron Aviation through a global network of service and part centres, mobile service units and 24/7 1CALL AOG support.

Future Air Navigation System (FANS) Controller Pilot Data Link Communication (CPDLC) and Aeronautical Telecommunications Network (ATN) Protected Mode CPDLC (PM-CPDLC) replace the traditional voice communications used by pilots and controllers with data/text messaging for many standard operating procedures, allowing pilots to communicate with air traffic control with the touch of a button. This increases pilot heads-up time, frees up VHF voice communication bandwidth for more critical communications and significantly reduces voice readback errors. CPDLC is similar to SMS text messaging used on your personal cell phone but uses prescribed text messages that enable pilots and air traffic controllers (ATC) to quickly and accurately request and authorise clearances and flight plan changes.

“Having the ability to communicate quickly and effectively with ATC is one of the highest priorities in the cockpit,” says Brian Rohloff, senior vice president, customer support, Textron Aviation. “The FANS 1/A+ and Protected Mode CPDLC upgrade brings the latest data communications technology to our Hawker 4000 and Citation Sovereign operators, and we remain committed to continuing to expand the capabilities for all of our products.”

The FANS 1/A+ and Protected Mode CPDLC programme features: Ease of operation by quickly and accurately loading complex instructions into the aircraft flight management system with the push of a button; Support for future FAA next gen data comm capabilities; Trajectory-based operations; Improved re-routing of aircraft around severe weather events and traffic congestion; and prioritised departure clearances that can save several minutes of wait time before takeoff.

Aircraft operating in continental Europe will also be able to use PM-CPDLC to obtain equivalent benefits of ATC prioritisation, delay avoidance and optimal flight durations.

Textron Aviation's collaboration with Honeywell on this project enables a cost-effective solution for customers for modernising the data Llnk capabilities of these important aircraft and reduces the certification and installation time. As the original equipment manufacturer of the aircraft, Textron Aviation can offer the OEM-certified upgrade to the Primus Epic avionics suite that maintains the system integrity as originally certified. Installation can be completed at any domestic or international Textron Aviation service centre.

Customers interested in learning more about the data communications programme and availability may reach out to the Textron Aviation service sales team.
