Five Technologies That Make Flying Safer

Over the last 100 years, Honeywell and its legacy aerospace companies have made countless innovations in efficiency, reliability, passenger comfort and perhaps most important…flight safety.


Here are five standouts, showing how the aviation industry continually builds on previous accomplishments.


Five Honeywell Technologies That Make Flying SaferAvoid Flying into the Ground
In 1975, Honeywell engineers developed the first Ground Proximity Warning System (GPWS) to help with controlled flight into terrain. Honeywell’s subsequent Enhanced GPWS (EGPWS), introduced in 1996, combined a worldwide digital terrain database and global positioning system technology. These innovations have been credited with saving thousands of lives.

Avoid Midair Collisions
As devastating as an aircraft crashing into a mountain may be, one of the worst aviation fears is that of two planes colliding in midair.

The Traffic Alert and Collision Avoidance System (TCAS) was designed to prevent these collisions by monitoring the airspace around an aircraft and warning pilots of the presence of other transponder-equipped aircraft. Since this all takes place independent of air traffic control, the system works anywhere over land or sea.


In 1990 Honeywell’s Bendix/King became the first company to receive FAA manufacturing authorization.

Manage Weather Conditions
Five Honeywell Technologies That Make Flying SaferAdverse weather poses a direct and real threat to aircraft, costing the aerospace industry billions of dollars each year through delays, cancellations, diversions, disasters, turbulence and severe storm activity. While developments in weather radar systems have been steady since World War II, Honeywell made a significant advance when it introduced IntuVue™ 3D weather radars in 2008.


The IntuVue RDR-4000 continuously and automatically scans all the weather in front of the aircraft, storing data in a 3D buffer, thus creating a three-dimensional image of the weather and terrain, reducing pilot workload and increasing situational awareness for maximum safety.

Coordinate Airplane Arrivals and Takeoffs
It's important that an aircraft’s movements coordinate with the hundreds of other aircraft utilizing the airport.

Honeywell’s SmartPath Ground-Based Augmentation System (GBAS) reduces flight delays for passengers while helping airline operators reduce fuel costs and traffic congestion by transmitting digital data to the aircraft. Unlike traditional instrument landing systems, Honeywell’s GBAS is immune to interference from weather, other aircraft and rugged terrain.

Our SmartPath GBAS is the world’s only certified satellite-based navigation and precision landing system.

Safer Arrivals and Takeoffs
Five Honeywell Technologies That Make Flying SaferSmartLanding™ and SmartRunway™ build on existing Honeywell EGPWS technology to address runway incursions (unauthorized aircraft or vehicle on a runway) and excursions (aircraft departing a runway inappropriately during take-off or landing) — an almost daily occurrence.


SmartLanding alerts the crew if the aircraft is unstable on approach or is landing too far down the runway — a cost-effective way to reduce risk during a critical phase of flight. SmartRunway alerts pilots about runway and taxi locations.
