Avoiding airplane collisions at airports may come all the way down to alerts

ABOARD A HONEYWELL TEST PLANE — Aerospace large Honeywell is constructing new cockpit alerts that builders say will give airline pilots extra valuable time to react to hazards at airports.

Honeywell senior take a look at pilot Capt. Kirk Vining late final month put the alerts — known as Floor Alert, or SURF-A — to the take a look at by recreating a number of the most severe close to disasters at airports in current aviation historical past.

Moments earlier than touchdown at Topeka Regional Airport, a Gulfstream G550 enterprise jet was stopped on the identical runway the place Vining was about to the touch down on the Kansas airport.

“Site visitors on runway!” known as out the automated alert within the cockpit of Honeywell’s take a look at airplane: a 43-year-old Boeing 757, as Vining pulled up, aborted his touchdown and flew across the airport safely.

A bunch of great shut calls lately has raised considerations about easy methods to higher keep away from them in ever-more congested airports. The Nationwide Transportation Security Board and different security consultants have urged extra superior cockpit alerts like those Honeywell is testing.

Runway incursions, when a airplane, individual or car is on the runway once they should not be, averaged 4.5 a day final yr. The Federal Aviation Administration categorizes them by severity, the place the highest and rarest two are: “a severe incident through which a collision was narrowly prevented” adopted by “an incident through which separation decreases and there’s a vital potential for collision could lead to a time-critical corrective/evasive response to keep away from a collision.”

Severe runway incursions at U.S. airports peaked at 22 in 2023, probably the most in at the least a decade. The FAA has added new lighting and different security know-how at airports across the nation to attempt to get to its objective of zero shut calls.

“He is superb at being a foul pilot,” Thea Feyereisen, a distinguished technical fellow for Honeywell Aerospace Applied sciences, stated of Vining. Her unit develops new cockpit options for aviators, and she or he stated she expects the brand new suite to win regulator certification subsequent yr.

“Seconds rely whenever you’re working close to the runway, and the earlier you’ll be able to let the pilots know of a possible severe state of affairs, the higher,” Feyereisen stated.

The Honeywell take a look at airplane wasn’t configured like an everyday passenger jet, and there weren’t any paying prospects on board. It had a set of roomy seats towards the entrance of the airplane, however within the again, Honeywell flight engineers had been positioned at consoles, monitoring flight information and the alerts in actual time. Earlier that day, Honeywell demonstrated the know-how on a flight with Division of Transportation, FAA and NTSB officers on board, an organization spokesman informed CNBC.

Vining carried out a simulation of one other incident from 2023, when an American Airways 777 sure for London crossed a runway the place a Delta Air Traces 737 was taking off as an alternative of holding in need of the runway as an air visitors controller instructed. The Delta pilot in that state of affairs aborted takeoff and each planes landed safely at their locations.

Honeywell stated its SURF-A alerts may have given the pilots 10 extra seconds of response time with a possible collision discover. The brand new program Honeywell is testing makes use of Automated Dependent Surveillance – Broadcast, or ADS-B information, a GPS for an airplane.

“It is often an excellent working surroundings between pilots, air visitors management, airport administration,” Vining stated. “We get it performed safely, effectively and easily. However you possibly can additionally see simply the slightest interruption, a little bit variation, and issues can go mistaken in a short time.”

The aerospace large already gives one other suite of alerts that tells pilots in the event that they’re about to make a mistake like touchdown or taking off on a taxiway as an alternative of a runway, for instance, with visible alerts on a display screen in addition to aural warnings — “Warning! Taxiway!” The so-called Good X bundle additionally alerts pilots if flaps should not set accurately, if the runway is just too brief, or if they’re coming in too excessive or too quick, amongst different conditions.

“As plane get nearer to the airports the place there are different airplanes which might be additionally flying low to the bottom, trying to land, that is probably the most harmful spot to have a collision happen,” stated Jeff Guzzetti, a retired air security investigator with the NTSB and the FAA. 

These alerts have been on Alaska Airways planes for years and, extra not too long ago, Southwest Airways has added them. Honeywell stated the alerts are at present flying on greater than 3,000 planes operated by 20 airways, however that is nonetheless restricted adoption with lots of of carriers working worldwide.

“Since we have applied the software program, I am unable to consider an occasion the place we have had a runway incursion,” stated Dave Hunt, Southwest’s vp of security and safety and a 737 pilot.

American Airways was additionally coaching its pilots on these alerts within the second quarter of the yr, based on a lesson plan that was seen by CNBC. Final month, American obtained its first plane with the runway consciousness and different alerts on board, a spokeswoman stated, including that its Boeing 737 pilots have now been educated on the instruments.

The alerts aren’t required by regulators, however the FAA stated it’s “reviewing suggestions” from the Runway Security Alerting Subgroup “to find out subsequent steps,” referring to a bunch of airline, aerospace, pilot union, authorities and trade officers that final yr beneficial new planes embody extra superior cockpit alerts in case of situational consciousness points at airports.

“The alerts happen additional away from the runway in order that if there’s an plane on the runway, you are not having to make that call very low to the bottom,” stated Jon Websites, director of flight operations security at Alaska Airways.

The US is the busiest aviation market on the planet, with 44,000 flights, carrying 3 million vacationers a day. Severe aviation accidents are uncommon, and deadly crashes are rarer nonetheless.

However an almost 16-year streak with out a deadly incident was damaged on Jan. 29 when an Military Black Hawk helicopter collided into an American Airways regional jet that was moments away from touchdown at Washington Reagan Nationwide Airport, killing the 67 individuals aboard the 2 plane and elevating considerations about congested U.S. airspace to a fever pitch. 

The aviation trade depends on a so-called Swiss cheese security mannequin, the place every slice offers safety however comes with holes which might be ideally lined when security measures are stacked on prime of each other.

“Aviation is constructed on layers of security upon layers,” stated Websites at Alaska Airways.

Honeywell’s demonstration flight final month from Charles B. Wheeler Downtown Airport in Kansas Metropolis, Missouri, recreated an actual incident that passed off on a foggy morning in February 2023 in Austin, Texas, when a FedEx Boeing 767 airplane aborted touchdown seconds earlier than touching down on the identical runway from which an air visitors controller cleared a Southwest 737 to take off.

The FedEx pilot had seen the define of the Southwest airplane by means of the fog and pulled up and later landed safely. Each flights continued to their locations safely, however the two plane had gotten as shut as 150 toes aside, lower than the size of the FedEx 767, based on federal security investigators.

Feyereisen stated Honeywell’s know-how may have supplied the FedEx pilots within the 2023 Austin incident 28 seconds of superior discover of visitors on the runway, once they solely had a number of moments to react, based on a report from the NTSB.

Feyereisen stated the brand new know-how might be retrofitted on older plane and is on the market for brand spanking new jets.

“Basically, the software program prices tens of 1000’s of {dollars} [per plane], however not lots of of 1000’s of {dollars},” Feyereisen stated. “So for those who’re [a] $150 million plane … it’s lower than a half a penny per passenger value to the operation.”

Southwest this yr added the software program to its fleet of about 800 Boeing 737s. It value between $20 million and $30 million to outfit the planes, Hunt stated.

“It’s cheaper than an accident,” he stated.

On Feb. 25, a Southwest airplane aborted its arrival after it was cleared to land at Chicago Halfway Worldwide Airport when a Bombardier Challenger 350 enterprise jet superior onto its runway, with the Southwest jet passing lower than 200 toes between the plane, earlier than safely touchdown after a go-around, based on the NTSB.

Such shut calls “are very, very uncommon, however clearly they’re one thing which might be regarding and that we’d attempt to mitigate as a lot as doable,” stated Hunt. The Honeywell software program is “very efficient at making certain our pilots are conscious of the place they’re on the airport” and “does a very good job of stopping inadvertent runway incursions whereas taxiing,” he added.

When growing the warnings, Feyereisen stated it is key to not overwhelm pilots with an excessive amount of info, referred to as “nuisance alerts,” which may find yourself being a distraction from vital security duties moderately than a assist.

“In case you’re blasting alerts by means of a cockpit speaker at low altitudes throughout a vital part of flight, similar to method to touchdown or takeoff, the place pilots’ consideration must be totally targeted … you create too many distractions,” Southwest’s Hunt stated.

There are additionally limitations to the present alerts and the brand new packages Honeywell is testing. To keep away from in-air collisions, industrial plane are required to have what’s known as the Site visitors Alert and Collision Avoidance System, or TCAS, which helps them see visitors round them in shows within the cockpit. However that system is mostly used for altitudes of at the least 1,000 toes.

That might not have essentially helped the pilots on the American Airways airplane that was beneath 400 toes within the deadly collision with the Black Hawk helicopter in January in Washington, D.C.

“We’re exploring alternate options to shut that hole the place you sort of can merge TCAS and ADS-B-type info collectively,” Feyereisen stated. 

Websites, the security director at Alaska, stated the D.C. crash was “an enormous, surprising occasion within the trade, however it’s simply, I feel, our observe file by means of the final 50 years reveals that it is a very, very uncommon occasion.”

“That is why we proceed as an trade to attempt to discover even higher know-how on the market and enhancements to the present know-how to maintain this from ever occurring and take the likelihood all the way down to as low a degree as doable,” he stated. “I do not know if in any aviation system you will ever get to zero, however I imply, we’ll attempt to get as near zero likelihood as we will.”
