Don Bateman, Trailblazer in Airline Safety, Dies at 91

6 min read


Don Bateman, an engineer who invented a cockpit system that warns airplane pilots with colorful display screen shows and dire audible alerts like “Caution Terrain!” and “Pull Up!” when they are in danger of crashing into mountains, buildings or h2o — an innovation that has likely saved countless numbers of life — died on Could 21 at his house in Bellevue, Clean. He was 91.

His daughter Katherine McCaslin explained the induce was complications of Parkinson’s disorder.

The floor proximity warning technique that Mr. Bateman commenced operating on in the late 1960s, and ongoing to enhance until finally he retired from Honeywell International in 2016, warns pilots towards accidentally slamming into land or drinking water for the reason that of bad visibility and undesirable weather conditions, after the most popular bring about of airline fatalities.

That classification of airplane crash has virtually been eradicated. According to info compiled by Boeing about business jets all over the world, there were just six these types of mishaps from 2011 to 2020, killing 229 folks onboard, compared with 17 incidents from 2001 to 2010, which left 1,007 people today dead, and 27 accidents from 1991 to 2000, killing 2,237.

“Don Bateman and his group have in all probability saved extra life by way of basic safety process technologies than any one else in aviation heritage,” Charley Pereira, a previous senior aerospace engineer with the Nationwide Transportation Basic safety Board, wrote in an e mail, estimating the selection in the hundreds.

“He was quite passionate,” Mr. Pereira extra. “He was a normal engineer, with pocket protector and pencils and pens, but he taught me what it indicates to be a security engineer.”

Mr. Bateman was inducted in the Countrywide Inventors Corridor of Fame in 2005 and been given the Nationwide Medal of Technologies and Innovation from President Barack Obama in 2011 for establishing and championing “flight-security sensors, like floor proximity warning and wind-shear detection programs, now applied by more than 55,000 aircrafts throughout the world.”

Bob Champion, a former scientist at Honeywell who labored with Mr. Bateman, explained in a telephone job interview: “Don had a accurate passion for conserving life. He was a peach, but powering closed doorways, when we were being hashing points out, he could be a pit bull.”

Mr. Bateman was a pilot in his have correct, flying a solitary-engine Cessna 182.

“He in no way missing his childlike speculate about traveling,” Ms. McCaslin explained by phone. “He did a lot of his wonderful do the job from his 40s on. He started flying and operating in his 40s and went on to do 50 marathons. And he had his final boy or girl at 54.”

Charles Donald Bateman was born on March 8, 1932, in Saskatoon, Saskatchewan. His father, George, fixed watches and owned a jewelry retailer. His mom, Gladys (Noel) Bateman, was a homemaker. They divorced immediately after World War II.

Don’s desire in airline protection started when he was 9, when just one of his mates seemed outside their classroom window in Saskatoon and noticed particles and what appeared to be individuals falling from the sky. Two military planes, with 10 guys aboard, had collided in midair. Don and his good friend sneaked out of school early and rushed to the crash web site.

“I experienced under no circumstances observed blood right before from a human remaining,” he advised The Seattle Moments in 2012. “It was awful.”

Right after graduating from the College of Saskatchewan in 1956 with a bachelor’s diploma in electrical and electronics engineering, Mr. Bateman worked as a television mend technician and owned a Television set restore store. He was employed by Boeing in 1958, then moved to United Control, an aircraft electronics organization two a long time later on. The company’s aviation devices enterprise is now part of Honeywell.

Mr. Bateman instructed the Nationwide Science and Know-how Medals Foundation in 2011 that in the late 1960s there were lethal incidents approximately every thirty day period, throughout which a pilot would “fly into anything, like a mountain, or go in brief on the runway.”

At the time, pilots employed the altimeter, which measures altitude, terrain charts and visual cues to steer clear of mishaps. “But in lousy visibility and clouds, people cues had been fewer effective,” Dr. Hassan Shahidi, president of the Flight Safety Basis, explained in an interview.

Established to do something, Mr. Bateman designed — and in 1974 patented — his initially ground proximity warning program: a little box that integrated details from in the plane, like the radar altimeter and airspeed indicator, and gave the pilot a 15-second warning of an approaching harmful condition.

The machine was in constrained use in 1971 when Alaska Airlines Flight 1866 — a Boeing 727 jet that was utilizing an early model of the method — slammed into a fog-covered mountain in the Chilkat variety in Alaska on its method to landing in Juneau, the funds. All 111 men and women aboard died.

Two weeks later on, Mr. Bateman adopted the exact route of Flight 1866 as the passenger in a tiny aircraft outfitted with his device. The alarm sounded with seconds to spare, giving the pilot more than enough time to fly to safety. But Mr. Bateman realized that it was not adequate time for the Alaska Airlines pilot to have reacted.

“I was disappointed,” he told in 2016. “We desired to do far better.”

He did. In 1974, the program had enhanced more than enough, providing before warnings, for the Federal Aviation Administration to mandate its set up into all domestic plane. The agency acted soon after a TWA flight crashed into a wooded slope in Virginia that yr, killing 92 men and women, an incident that prompted a Congressional panel to criticize the company for delaying steps to enhance airline safety.

In the 1990s, the program improved exponentially. Engineers doing the job with Mr. Bateman added GPS and vital terrain details, which include topographical maps of Eastern Europe and China that had been charted by the Soviet Union as significantly back as the 1920s they had been acquired in Russia at Mr. Bateman’s request.

“We knew, as engineers, that if we could get the terrain details, we could do an dreadful lot,” he advised The Seattle Occasions.

Critically, the rechristened Increased Floor Proximity Warning Technique, or EGPWS, gave pilots a two-minute warning of obstacles ahead. In 2000, properly immediately after a lot of important industrial airlines had presently started utilizing the system, the F.A.A. expected that it be put in in all registered turbine-powered airplanes with 6 or much more passenger seats.

In addition to Ms. McCaslin, Mr. Bateman is survived by his spouse, Mary (Contreras) Bateman a different daughter, Wendy Bastian two sons, Greg and Patrick eight grandchildren and two excellent-grandchildren. His relationship to Joan Berney ended in divorce. A third son, Dan, died in 1988.

In 2015, Mr. Bateman wrote in Hindsight magazine, an airline safety publication, about 6 current, independently investigated incidents in which the warning procedure averted disaster.

In 2014, for illustration, the crew of a Saab 2000 twin-motor turboprop dropped control of the aircraft around Sumburgh, Scotland, soon after failing to identify that the autopilot was however on following a lightning strike. But, Mr. Bateman wrote, the crew “recovered from a substantial rate of descent towards the sea area after EGPWS warnings transpired.”
