6 Reasons to Upgrade to the Honeywell Aerospace Mark V-A EGPWS Today

We made aviation history 30 years ago with the Mark V enhanced ground proximity warning system (EGPWS), which set a new standard in terrain awareness and warning technology. The Mark V has saved countless lives since then by improving situational awareness and helping pilots avoid controlled flight into terrain (CFIT) accidents.

After 30 years of trusted service, we are sunsetting the Mark V because aging hardware and component obsolescence make long-term support impractical. The new Mark V-A builds on the Mark V legacy, delivers better overall performance and improves safety with new features that meet the challenges of the evolving aviation ecosystem.

Here are six reasons you should make the move now to the Mark V-A EGPWS.

The Mark V-A expands safety beyond terrain awareness with newly available runway safety capabilities, including surface awareness (SURF-A) technology. With SURF-A flight crews can identify potential runway conflicts, unstable approaches and runway occupancy hazards during taxi, takeoff and landing operations. By giving flight crews earlier alerts and greater situational awareness, the system helps pilots respond more quickly to emerging runway safety risks.

As global navigation satellite system (GNSS) jamming and spoofing incidents increase, resilient navigation and safety systems are more important than ever. The Mark V-A incorporates enhanced protection against navigation signal interference, helping maintain dependable terrain awareness and warning performance even in challenging operating environments. Advanced algorithms and improved processing capabilities help the system deliver faster, more accurate alerts when pilots need them most.

The original Mark V established an exceptional reputation for reliability, but maintaining legacy hardware becomes increasingly difficult as hardware and parts become harder to get. The Mark V-A uses modern electronics and updated architectures that improve system reliability, simplify maintenance and support long-term fleet readiness. You will benefit from lower maintenance burdens, improved dispatch reliability and continued access to Honeywell Aerospace support and future software enhancements.

Terrain databases are at the core of EGPWS performance, giving pilots the information they need to maintain awareness of terrain, obstacles and runway environments. As support for the legacy Mark V platform winds down, terrain database updates will eventually cease if you remain on the older system. Upgrading to the Mark V-A ensures uninterrupted access to terrain database updates and ongoing support, helping you maintain the highest levels of safety, accuracy and operational readiness.

We designed the Mark V-A to make the transition from your current EGPWS as seamless as possible. The upgrade path minimizes aircraft downtime and simplifies installation planning, helping you modernize efficiently without extensive aircraft modifications since the Mark V-A uses the same footprint as the legacy systems. Honeywell experts work closely with you to develop tailored transition strategies based on fleet configuration, maintenance schedules and operational requirements.
