Jon Wade flies over Saskatchewan in
a flight simulator at Carleton's ACE lab. |
“This isn't going to be good,” mumbles the young
pilot.
The plane plummets towards a tiny strip of runway, only
inches away from the rudder of the other aircraft.
Wade pushes his hands away from the controls and shakes
his head.
The plane crashes and swerves off the runway.
Thankfully, this is only a simulation.
But for researchers at Carleton University, these types
of simulations are not just for entertainment; they are used
to help keep pilots safe.
Currently, psychologists from Carleton’s Advanced
Cognitive Engineering Laboratory, or ACE Lab, are working on a study
that will help to determine the effects of aging on the cognitive
abilities of pilots.
Matt Brown, a psychologist involved in the research, says
this type of study is important because there are no formal
tests in Canada to measure a pilot’s cognitive abilities.
“This is a fairly important issue because right now
the only screening in place for pilots is medical. Basically,
there is only screening for physical capabilities of the
body. There is no screening for mental capabilities,” says
Brown.
Although the research has just started, preliminary testing
on desktop computers has shown that older pilot’s cognitive
abilities are somewhat lacking, says software engineer, Jon
Wade.
“Older pilots were much slower to respond to increased
workloads,” says Wade.
According to Brown, as pilots age, their ability to respond
to multiple tasks decreases. An older pilot may be fine flying
in clear skies and good conditions, but if they are flying
in a storm or handling equipment failures, their responses
tend to be slower than younger pilots, he says.
This does not come as a surprise to flying instructor Simon
Garrett. Garrett has been flying for 37 years and began working
at the Rockcliffe Flying Club in Ottawa 11 years ago.
Over time, Garrett says he has observed changes in the flying
habits of many of his regulars.
“I noticed that as these pilots got older, and even
just the older pilots coming to the club, many had delayed
reaction times.”
Making safer pilots
Anne Barr, a simulation specialist at Carleton and a general
aviation, non-commercial, pilot says Transport Canada, the
Canadian Owners and Pilots Association and the Air Transport
Association of Canada have also expressed interest in this
research.

recreational pilots. |
“The general aviation community is very safety conscious
and self-aware,” she says. “We are trying to
inform the flying community about where problems occur and
how to spot early warning signs.”
Although they are interested in helping the flying community
identify unsafe flyers, the lab is not trying to ground aging
pilots, says Brown.
“We want to help them identify their areas of difficulty
and then show them ways they can improve.”
Garrett says he feels the same way.
“For pilots who are passionate about flying, it is
their life, and we don’t want to take their lives away.”
But not all pilots are interested in flying past their prime.
Retired Air Canada pilot, Jim Strang, 69, says he never
felt like he was forced to stop flying because of age.
“I probably could have kept flying if I had wanted
to, but at that point I was tired and ready to call it quits.”
Our aging brains
Psychology professor, Sylvain prGagnon, says it is typical
for the physical health of pilots and drivers to decline
before their mental health.
“Driving and flying are not just about cognition because
there are also biomechanical processes involved,” he
says.
Gagnon’s research at the University of Ottawa focuses
on the neuropsychology of aging.
Although Gagnon says he acknowledges a direct link between
aging and the decline of mental abilities, he asserts that
this does not always translate into better performances from
younger pilots and drivers.
“Older drivers know they may have a slower reaction
time, so they will keep a further distance between cars so
they have more time to react,” he says.
Strang warns that not all older pilots are better flyers.
“Although we all say we could have kept going at age
60, I think all of us will know at least one or two individuals
who should have retired much earlier because of deteriorating
cognitive abilities,” he says.
Those involved in Carleton’s aging pilot study are
well aware of these individuals.
But Brown says he hopes this research will help create a
validated screening process that can identify these pilots
who are not meeting the minimum cognitive standards.
“Often small private aircrafts go down without any
evidence of mechanical failure and these accidents seem to
happen more commonly these days,” he says. “We
just want everyone to be safe.”
