If you knew what pilots know about
turbulence, you’re sure to find flying more relaxing. There is a real ‘feeling
of what on earth is this’ when you hit turbulence while flying. Without getting
overly scientific, this post will try to take some of the mystery out of
turbulence and explain what it means for you. We hope that this will reduce
stress levels on your next flight and maybe even allow you to enjoy the process
a bit more.
Before we get in to the details, it
is important to point out that pilots really do not like bumpy air and will do
everything they can to avoid it. Aircraft are equipped with highly modern
surveillance equipment and science allows us to predict areas of turbulence;
however, sometimes you just can’t avoid it.
Turbulence is the Primary Cause of
Non-fatal Aviation Accidents
In the 28 years from 1980 to 20008
the National Transportation Safety Board (NTSB) reported nearly 300 serious
injuries attributed to turbulence. Nearly two thirds of these involved flight
attendants and 114 passengers suffered injuries over this nearly 30 year
period. Unfortunately, 3 people suffered fatal injuries. Interestingly, 2 of
those were not wearing their seatbelts when instructed to do so and would
probably have survived if they had been.
The safest thing to do is keep your
seatbelt fastened; pilots always wear theirs. This is also why most airlines
recommend wearing your seatbelt even when the sign is switched off.
American Geography Leads to
Turbulence.
The convergence of jet streams at
the altitude of modern airliners and the numerous mountain ranges are causes of
much turbulence. This and other factors mean that the geography of the United
States naturally produces turbulence. It also means it is relatively easy to
predict.
The good news is that with a
detailed knowledge of the natural causes of turbulence and access to the latest
meteorological data, flights are planned to avoid these areas.
The Convergence of Jet Streams
Creates Turbulence
A jet stream is a wind of greater
than 50 knots. Further, these winds are normally stronger during the winter
months than in the summer. Jet streams will normally gust west-east and jet
aircraft take advantage of this fact by flying in them when heading east. Jet
streams are avoided by aircraft traveling west, as the tail wind would slow the
aircraft and require a higher fuel usage.
Flight plans will include a
depiction of jet streams on the chosen route. This means that the pilot can
warn passengers and cabin staff when the aircraft is about to enter an area
where two jet streams overlap. This is why you often have the seatbelt light
switched on before the turbulence arrives.
