West Star Aviation Expands FAA STC Portfolio with Modern Honeywell CD-830 Display Upgrade

As business aircraft continue to remain in service longer, avionics obsolescence has become one of the industry’s biggest maintenance challenges. Operators are increasingly faced with aging equipment that is no longer supported, difficult to repair, or dependent on components that are no longer manufactured.

To help address this growing issue, West Star Aviation continues to expand its portfolio of FAA Supplemental Type Certificates (STCs) with practical, cost-effective solutions that extend the life of legacy avionics systems.

One of the latest additions is FAA STC ST00818DE, an Approved Model List (AML) STC that authorizes the installation of the Honeywell CD-830 Flat Panel Display across 40+ aircraft models representing five major aircraft manufacturers.

A Modern Solution for an Obsolete Display

Many business aircraft continue to operate with legacy Honeywell Cathode Ray Tube (CRT) control display units, typically found in older CDU’s like the CD-800, CD-810, CD-815 & CD-820 units. While these displays have served operators well for decades, they have reached the point where maintaining them has become increasingly difficult.

Much like replacing an old CRT television with today’s flat-panel LCD technology, the Honeywell CD-830 provides a modern replacement for aging display technology.

The legacy CRT displays present several challenges:

• CRT display technology is no longer manufactured
• Components are becoming increasingly difficult to source
• Units are heavier than modern flat-panel displays
• Higher electrical power consumption
• Reduced long-term reliability as systems continue to age

Rather than continuing to repair obsolete equipment, operators now have a straightforward path to modernization.

Honeywell CD-830: A Simple, “Plug-and-Play” Upgrade

One of the greatest advantages of the Honeywell CD-830 is its simplicity.

The unit is designed as a plug-and-play replacement for the legacy CRT display, allowing operators to modernize the cockpit without extensive aircraft modifications.

In fact, the physical replacement can typically be completed in just a matter of minutes — often taking less time than the required maintenance documentation.

The upgrade requires:

• No major panel modifications
• No extensive aircraft rewiring
• Minimal aircraft downtime
• Simple replacement utilizing existing installation architecture

This allows operators to quickly return aircraft to service while eliminating one of the more common avionics obsolescence concerns.

Benefits of the Honeywell CD-830 Upgrade

Replacing the legacy CRT display with the Honeywell CD-830 provides several operational advantages, including:

• Modern flat-panel LCD technology
• Elimination of obsolete CRT hardware
• Reduced aircraft weight
• Lower electrical power consumption
• Improved display reliability
• Increased long-term parts support
• Minimal installation downtime
• FAA-approved installation through West Star’s AML STC

For operators seeking to improve dispatch reliability while extending the life of their aircraft, the CD-830 represents a practical and economical modernization solution.

One STC. Multiple Aircraft Platforms.

Unlike traditional STCs that apply to a single aircraft model, ST00818DE is an AML STC, allowing the Honeywell CD-830 upgrade to be installed across 40+ aircraft models from five different manufacturers.

This broad applicability allows West Star Aviation to offer a common, proven solution to a large segment of the business aviation fleet while simplifying certification and installation planning.

Engineering That Sets West Star Apart

Developing an FAA Supplemental Type Certificate requires much more than approving a replacement component.

West Star Aviation’s engineering organization develops complete certification packages that include:

• Aircraft systems integration
• Electrical compatibility analysis
• Installation engineering
• Flight manual documentation
• Instructions for Continued Airworthiness
• FAA certification compliance

These in-house engineering capabilities enable West Star to deliver solutions that are technically sound, operationally efficient, and fully compliant with FAA standards.

Continuing to Build the West Star Aviation’s STC Library

ST00818DE is another example of West Star Aviation’s ongoing commitment to solving real-world maintenance challenges through innovative engineering.

As avionics technology continues to evolve and legacy systems become increasingly difficult to support, West Star continues expanding its portfolio of proprietary FAA STCs that help operators reduce downtime, improve reliability, and extend the useful life of their aircraft.

Whether replacing obsolete avionics, modernizing flight decks, or integrating the latest connectivity and cabin technologies, West Star Aviation remains one of business aviation’s leading engineering, certification, and modification resources.
