United Airlines Selected Honeywell To Supply New 25-hour Flight Data Recorders and 3D Weather Radar for its Next decade MAX fleet.

• The Honeywell RDR-4000 and -7000 use several methods to alert pilots of hazardous convective activity and make a deviation decision.
• The systems also provide a composite display of the data, showing the maximum reflectivity for any given point and indicate hazards relevant to the flight path.
• 25-hour CVR is provided by the HCR-25 (Honeywell Connected Recorder 25 hrs), which was developed in partnership by Honeywell and Curtiss-Wright.

In the Farnborough International Airshow (FIA), England, United Airlines has selected Honeywell to supply a wide range of avionics for new 737 MAX aircraft that will enter service over the next decade, including technologies such as the industry's only 3D weather radar, new 25-hour flight data recorders and advanced traffic avoidance systems.

United Airlines first selected a similar suite of Honeywell avionics in 2018 to equip 161 737 MAX aircraft, and this latest agreement builds on Honeywell's reliability in delivering world-class aerospace technology.

Heath Patrick, President, Americas Aftermarket, Honeywell Aerospace Technologies, said:

"We are proud to continue our long-standing relationship with United Airlines to provide advanced avionics for its growing 737 MAX fleet," "Our technology reduces pilot workload, improves situational awareness and supports dispatch reliability."

About the 3D weather radar system, Honeywell IntuVue RDR-4000 is a member of Honeywell’s family of advanced weather radar systems. IntuVue automatically scans the sky at 17 tilt angles – the most in the industry – and delivers a 3-D view of the weather through an intuitive display that pilots love.

The IntuVue RDR-4000 and RDR-7000 weather radars collect data from continuous scanning that looks at airspace from 0 to 60,000 feet and +/-60 degrees. When the data is put in the 3D volumetric buffer, it’s corrected for the earth’s curvature so that pilots will read true MSL (mean sea level) altitudes.

The IntuVue RDR-4000 3D Weather Radar System is available on the A320, A330, B737NG, B737Max, B777, E-170/175/190/195/E2, F5X, F7X, F8X and G650 platforms.

Honeywell will also provide the 25-hour CVR recorder by its Honeywell HCR-25 (Honeywell Connected Recorder 25 hrs), which was developed in partnership by Honeywell and Curtiss-Wright. The HCR-25 cockpit voice recorder supports four high-quality communications channels and a CPDLC datalink recording channel, each of which records for 25 hours.

The HCR-25 unit is fully ED-112A compliant and is designed to be installed into existing aircraft equipment trays, offering a simple upgrade path from current 2-hour voice recorders.

That's not all ! United Airlines selected the following Honeywell cockpit technologies for its 737 MAX fleet as a complete package:

• IntuVue RDR-4000 3D Weather Radar System is the first automatic commercial radar to accurately depict weather in the flight path of an airplane. IntuVue automatically scans the sky at 17 tilt angles — the most in the industry — and delivers a 3D view of the weather through an intuitive display that pilots can quickly and easily reference.
• Honeywell Connected Recorder – 25 is made for commercial air transport aircraft to accommodate mandatory flight data and cockpit voice recording. It may result in the potential for better maintenance predictability and operational insight through data analytics.
• Honeywell's TPA100B Traffic Alert and Collision Avoidance System and TRA 100B Transponders identify the aircraft to other surrounding aircraft via an airborne collision avoidance system.
• Integrated Multi-Mode Receiver is the industry's leader in radio navigation and combines satellite- and ground-based navigation systems into one receiver. It helps pinpoint precise airplane locations for efficient landings, especially during difficult and new runway approaches.
• The ALA-52B radar altimeter assists instrument landings at hundreds of U.S. airports and filters out 5G broadband interference.
