Four myths about air turbulence. How Dangerous Is It?

Turbulence is what nervous fliers worry the foremost after they board Associate in Nursing craft. it’s additionally the foremost common reason for injury to air passengers – within the U.S.A. alone there area unit an calculable fifty eight injuries annually thanks to turbulence. Pilots can forever keep their seat belts fixed whereas seated on an craft and can typically advise you to try to to a similar. however is it extremely one thing to be afraid of?. British Airways pilot Steve Allright explains what exactly is Turbulence.

10 things which is really special for US president in AIR FORCE ONE(Opens in a new browser tab)


What causes turbulence?

Many different things could cause turbulence, however every and each one in all them is thought and understood by pilots. a day I fly, I expect alittle quantity of turbulence, even as I’d expect the odd bump within the road on the drive to figure. Turbulence is uncomfortable however not dangerous. it’s a part of flying, and isn’t to be feared.

Different aspects of the weather cause differing types of turbulence. CAT is associate degree abbreviation for Clear Air Turbulence – the foremost common type of turbulence you’re probably to expertise.

Air tends to flow as a horizontal snaking river known as a jet stream. A airstream will typically be thousands of miles long however is sometimes solely some miles wide and deep. looking on the direction of travel, our flight planners either avoid (into a headwind) or use (into a tailwind) these jet streams to chop fuel prices, as they will flow up to 250 mph. rather like a fast-flowing watercourse whirling against the bank, wherever the sting of the airstream interacts with slower moving air, there could also be some mixture of the air that causes turbulence.

Can or not it’s avoided?

You cannot see CAT, you can not sight it on measuring system and you can not accurately forecast it, however there square measure different ways that of avoiding it. within the main we tend to consider reports from different craft, that we tend to hear either directly or that square measure passed on by traffic management. we tend to then take into account the choices out there to America. Our endeavours to fly at associate degree altitude that has been reportable as swish could also be prevented by many constraints such another craft occupying that level, or the burden of the craft at that point.

Whatever the circumstances, your pilot can realize the foremost snug path to your destination while not compromising your safety. rather like you, we tend to expertise the movement and would favor a sander ride.

Is turbulence additional probably on certain routes?

Any field is at the mercy of sturdy winds on any given day. an equivalent applies to jet streams on any given route, though there’s typically additional likelihood of turbulence crossing the ITCZ (Intertropical Convergence Zone) once flying south across continent, to Illustrate.

How dangerous will turbulence get?

Flight crews round the world share a standard classification of turbulence: light, moderate and severe. The definitions square measure set down in our manuals associate degreed facilitate America to create an assessment on what our course of action ought to be. For the fearful flyer, even light turbulence are often disconcerting. For pilots, light turbulence is not any different to a rough road for a taxi driver or a rather uneven section of track for a train driver – a small, however all safe, inconvenience and really much a part of our daily lives. In light turbulence, the craft could also be deviating by simply some feet in altitude.

Moderate turbulence strikes no worry into pilots, as they will experience this level of turbulence for some hours in each thousand hours they fly. it always lasts for no over ten or quarter-hour, however often might last for many hours, on and off. this type of turbulence can enervate even some regular travellers and can cause drinks to spill. The craft could also be deviating in altitude by ten or twenty feet. No action is needed by the pilot to regulate the aircraft, however the flight crew might commit to attempt a special altitude if the turbulence persists.

Severe turbulence is very rare. during a flying career of over 10,000 hours, I actually have concerning severe turbulence for about 5 minutes in total. it’s very uncomfortable however not dangerous. The craft could also be deviating in altitude by up to a hundred feet (30 metres) about, up moreover as down, however nothing just like the thousands of feet you hear some folks talking regarding once it involves turbulence.


I ought to stress that this level of turbulence is thus rare that leisure travellers can nearly actually ne’er expertise it and nor can most business folks.
