Cockpit footage of the runway incursion test scenario as the “Traffic on Runway” alert is triggered on final approach.
The alert came on short final. We were stabilized and a few hundred feet from landing when the cockpit filled with a voice that would put any pilot on high alert.
“Traffic on runway.”
From my position just behind the pilot flying, I could just make out a King Air, barely distinguishable against the threshold stripes, sitting on the runway near the touchdown zone where we would normally land.
Immediately, the pilots initiated a go-around exactly as briefed.
The scenario was executed precisely according to the test cards, designed to replicate a real-world conflict that has played out far less predictably in the past.
The Laboratory with Wings
The 1982 Boeing 757-200 we were flying aboard was Honeywell's flagship testbed—a heavily modified aircraft used to validate new technologies under a wide range of flight conditions. Over several days, flight crews, engineers, and support teams executed a choreographed series of test scenarios alongside a King Air 200 acting as a cooperative intruder aircraft.
The focus of the demonstration was SURF-A, a predictive surface alerting technology designed to reduce runway incursions and enhance pilot situational awareness during taxi, takeoff, and landing. Rather than simulating these events in a laboratory environment, the system was evaluated in live airspace, with real aircraft, controllers, and all the complexities that come with careful planning and real-world timing constraints.
Flight test personnel make their way to Honeywell’s 757 testbed ahead of a day of coordinated SURF-A flight testing.
Inside the 757 cabin, rows of vintage first-class seats coexist with engineering workstations, instrumentation racks, and telemetry displays, allowing engineers to monitor test performance in real-time.

Flight Coordination
Planning for this test began months in advance and involved many people, including air traffic control personnel at each airport involved in the operation. Factors such as traffic density, weather conditions, runway availability, and operational support all had to be considered.
When the official test week arrived, each morning began with detailed briefings that aligned pilots, engineers, and ground teams on the day's objectives. Operations repositioned from Atlanta's KATL to Southwest Georgia Regional Airport in Albany, selected for its lower traffic volume and operational flexibility.
Every action was carefully timed and planned, all part of a detailed series of test cards outlining each radio call, aircraft configuration, safety check, and decision point.
The Test Scenarios
Several primary scenarios were flown, each targeting different elements of the SURF-A and Smart-X suite:
- Aircraft occupying the runway during landing
- Incorrect flap configuration
- Wrong-surface landing and takeoff
- Aborted takeoff due to crossing traffic
- Excessive speed or glidepath deviations
The King Air was positioned on the runway to trigger predictive runway safety alerts aboard Honeywell’s 757 testbed during the scenario.
One sequence in particular felt all too familiar, resembling many recent incidents that have made national headlines.
As the 757 descended on final approach, the King Air held position on the runway ahead, replicating a conflict scenario in which two aircraft unintentionally come too close or fail to see one another despite multiple layers of safety procedures. Situations like this, though rare, can lead to serious consequences.
As we descended, the system triggered a “Traffic on runway” callout along with a visual alert on the primary flight display. Exactly as designed, it issued the alerts early enough to support a safe, stabilized go-around and fully de-conflict the situation well before it became critical.

From the Ground
To complete the visual narrative, I also documented the same scenarios from ground level, working along the extended centerline and within controlled areas near the runway environment. While Albany is a regional airport, the test profiles mirrored conflicts more commonly associated with larger, high-density hubs.
Aircraft movement, spacing, and timing leave little margin for error. Photographing from the ground helped convey how narrow those windows can be during takeoff and landing.
Access on the field required constant coordination and continuous communication with the tower. It was a tightly managed environment and one that offered a rare opportunity to document flight testing from unique perspectives near the runway environment.
The crossing King Air simulated a high-risk runway incursion scenario designed to trigger a runway traffic alert and rejected takeoff.
On the Extended Centerline
For the landing and go-around sequences, I worked with a Canon 400mm f/2.8 paired with a 2x extender, positioned just off the extended centerline at a safe distance from the active runway. Even in moderate conditions, atmospheric heat distortion became a factor near the surface.
Elevating slightly helped minimize inferior mirage effects, keeping the aircraft clearer as the test scenarios played out. The blurring caused by atmospheric heat distortion demonstrated how difficult it can be to see clearly down a runway, even in seemingly ideal weather and daylight conditions. At Albany, the distortion was noticeable, but at airports with hotter temperatures, it can become even more pronounced.
Advancing Aviation Safety
Observing these systems operate in real time offers insight into how cockpit technology evolves from concept to certification. For aviation and aerospace teams, accurately documenting that process is critical in communicating capabilities to customers, regulators, and other stakeholders.

SURF-A represents a meaningful step forward in predictive surface safety. As runway incursions continue to draw attention across the aviation industry, tools like this add another layer of protection during the most complex phases of flight. Elements of Honeywell’s broader SmartRunway and SmartLanding suite are already in service across major commercial fleets, including Southwest Airlines.
Reflections
This assignment brought together multiple threads of my background: engineering, aviation, and visual storytelling. Much of my aviation photography work centers on documenting aircraft operations and the people behind them. Between flight profiles, conversations with test pilots and engineers often drifted into how these systems are designed, validated, and refined through years of simulation, flight testing, and certification work before they ever reach the flight deck of a commercial aircraft.
Documenting part of that process from both the air and the ground underscored how much work goes into preventing incidents long before they happen, and how many people are involved in making modern air travel safer every day.
