4053000-922 – Honeywell DU-880 Color Display Unit
Available now on the Airparts.aero Marketplace.
Overview
The Honeywell 4053000-922 is the part number for the DU-880 Color Display Unit, a foundational component of the highly successful Honeywell Primus 1000 and Primus 2000/2000XP integrated avionics suites. This large-format, 8-inch by 8-inch display utilizes high-resolution Cathode Ray Tube (CRT) technology to present flight-critical information to the pilots. Depending on its position in the cockpit, the DU-880 functions as a Primary Flight Display (PFD) or a Multi-Function Display (MFD). It is the visual centerpiece of the flight deck in a wide range of an entire generation of market-leading business and corporate jets, renowned for its reliability and crisp presentation of complex data.
Key Features
- High-Resolution CRT Display: Employs a high-resolution, stroke-and-raster scan Cathode Ray Tube. This technology provides excellent contrast, color fidelity, and off-axis viewing angles, with the deep blacks and vibrant colors characteristic of CRT displays.
- Multi-Function Capability: A highly versatile unit that can be configured to operate as a PFD, displaying attitude, airspeed, altitude, and heading, or as an MFD, displaying navigation routes, weather radar, traffic (TCAS), and terrain (EGPWS) information.
- Seamless System Integration: Designed to be driven by the Honeywell IC-800 series Integrated Avionics Computers (IACs), forming the core of the Primus 1000/2000/XP flight deck. It seamlessly integrates data from all aircraft sensor systems.
- Robust Aerospace Design: Engineered to withstand the harsh environmental conditions of the flight deck, including extreme temperatures, high altitudes, and constant vibration, ensuring long-term operational reliability.
- Proven Service History: With millions of flight hours across a vast fleet of corporate jets, the DU-880 has a proven track record of performance and reliability, making it a trusted standard in business aviation.

Applications
The DU-880 is the primary visual interface between the pilot and the aircraft's complex systems:
- Primary Flight Guidance: As a PFD, it displays all critical information needed to manually fly the aircraft, including an Electronic Attitude Director Indicator (EADI) and Electronic Horizontal Situation Indicator (EHSI).
- Navigation & Situational Awareness: As an MFD, it provides graphical navigation mapping, weather radar overlays from systems like the Primus 880, and TCAS traffic displays.
- Engine & System Monitoring: Can display Engine Indication and Crew Alerting System (EICAS) data, providing a centralized view of engine parameters and system status.
- Avionics Overhaul & Repair: A key component for repair or replacement when troubleshooting display failures, color degradation, or focus issues in a Primus-equipped flight deck.
Why Choose 4053000-922?
The DU-880 is the window into the entire avionics suite of the aircraft. Its proper function is essential for safe operation in all phases of flight. Using a genuine, certified Honeywell 4053000-922 unit ensures that the display has the correct calibration, symbol generation, and interface compatibility to work seamlessly with the Integrated Avionics Computers. For maintaining the integrity and certification of a sophisticated flight deck like the Honeywell Primus, there is no substitute for genuine, traceable OEM components.

The Honeywell DU-880 utilizes Cathode Ray Tube (CRT) technology, where an electron gun at the rear of a vacuum tube emits a focused beam of electrons. This beam is precisely deflected by magnetic or electrostatic fields onto a phosphor-coated screen at the front. When the high-energy electrons strike the phosphor, it fluoresces, creating a bright point of light. By rapidly scanning this beam across the screen (raster scan for background images) and drawing vector graphics (stroke scan for symbols and text), the DU-880 "paints" the complex symbology of the PFD and MFD. This technology is known for its ability to produce very bright, high-contrast images with deep black levels, making it highly effective for readability in the variable lighting conditions of a cockpit, from direct sunlight to dark night operations.
Note: This is a flight-critical avionics component containing high-voltage elements. Installation, configuration, and testing must be performed by a certified Part 145 repair station or a qualified avionics technician in strict accordance with the manufacturer's installation manual and all applicable airworthiness regulations.
