“Buckle up folks. There’s some bumpy air ahead”, said the pilot
on a recent flight. No need to remind me;
my seatbelt is always fastened as “bumpy air”… a euphemism for air turbulence…
is my worst fear in flying. It’s the whole “fear of death” thing.
Intellectually I know that modern
aircraft can survive all manner of stress from changing or violent winds, but
can I? I’ve been on flights where our
aircraft plummeted hundreds of feet without notice, sending passengers, their
drinks and laptops flying. There’s not
much you can do in a situation like that except, hang on, breathe deeply and pray.
Thanks to climate change there are dire
predictions that in-flight turbulence
is getting worse, increasing by several hundred percent in some
areas. Even today severe air turbulence
is thought to cost airlines $200 million a year and is the single biggest cause of passenger
injuries.
According to the FAA there were 27
passengers and crew injured by turbulence in 2015. In 2016 that number was 42. And with more and more people flying those
numbers will climb.
Only a few years ago United Airlines offered
passengers an in-flight audio channel where they could listen to air traffic
control handling their and other flights.
That was my favorite channel as I heard our flight being cleared to
higher altitudes, warned about other aircraft and being guided across the
country. It was reassuring to hear the professionalism of the flight crew and
ATC. But the channel was only available
at the pilot’s discretion. And when it was turned off mid-flight I always knew
something nasty was coming our way.
Pilots regularly ask ATC for “ride
reports” from other aircraft at the same altitude and flight path, always
seeking the smoothest flight. But
sometimes the turbulence is unexpected, the so-called “clear air turbulence”. You can be cruising along at 35,000 feet
when, without notice, you get slammed.
On a Turkish Airlines flight to JFK last
March the 777 jetliner encountered clear air turbulence over Maine that sent
everything flying. The terror lasted
about ten minutes and when the plane finally landed, 30 passengers were taken
to the hospital.
That’s why you should always keep your
seatbelt fastened so if the plane drops, you don’t crash into the ceiling.
Now there’s new technology that may help
us all have a smoother flight.
The IATA, the International Air Transport Association, is testing an
automatic tracking and reporting system to warn flights of “bumpy air”. So far 15 major airlines are sharing data in
the test phase of the program.
Their planes are equipped with a black
box measuring changes in the flight’s speed and tilt eight times each
second. That data is transmitted to the
ground and within 30 seconds flights in the area can be warned of trouble
ahead.
So far the participating airlines are
generating 115,000 reports a day to the IATA Turbulence Aware system. The system will be most valuable on long,
overseas routes where there are fewer aircraft flying the same corridor.
The Turbulence Aware
system should be fully operational this year when airlines will
have installed the gear on most of their planes. American Airlines alone hopes to have 800
airliners gathering and reporting data in the coming months.
Meantime… buckle up, friends! There’s bumpy air ahead.
