why do planes crash in bad weather

AirAsia Flight QZ8501 was reported to have been navigating around large thunderclouds before it went missing, with reports suggesting the captain had asked for permission to take the plane higher. According to Gloria Kulesa of the Federal Aviation Administration, the weather is a primary contributing factor in 23% of all aviation accidents - including both serious and minor - across the globe. Wherever a plane has been lost in or near a storm there is always speculation about what part the weather might have played. For instance, although it has not yet been established why Air Algerie Flight 5017 crashed in the Sahara in July, killing all 118 people on board, there had been
of bad weather. But it's very rare for the weather alone to cause airliners to crash, experts say. Instead, how pilots and crew operate the plane mostly determines whether an incident will end up being a fatal accident, says Sylvia Wrigley, a light aircraft pilot and author of Why Planes Crash. "I can't think of an accident where weather was the sole cause of the problem," she says. "But there can be a situation where the weather puts the aircraft at a higher risk of going wrong. " Very powerful storms might be able to seriously damage the wings on a small aircraft but, typically, pilots and air traffic controllers make great effort to avoid them.


Crews aim to fly at least 10 miles (16km) around the worst ones. Nose-mounted weather radar technology has made it far easier to detect - and thus steer away from - dangerous weather conditions. Another crash where the weather was examined as a factor was the Air France plane lost in the Atlantic in 2009. After hitting turbulence, the pilots failed to discuss repeated stall warnings and did not have the training to deal with the situation,. A build up of ice on the wings can cause problems, but pilots are trained to deal with it A build-up of ice on the wings or tail can, but pilots are trained to avoid this.


In addition, aircraft wings are fitted with "static wicks", which dissipate the electricity from lightning strikes safely. It is that each commercial airliner is struck once a year. Heavy rain or sleet has also been known to cause "flameouts" - where the engine's flame is extinguished. The engine can usually be restarted by the pilot but not always. A Garuda Indonesia Airways 737 plane experienced a double engine flameout. Although the pilots were unable to restart the engines they managed to guide the plane down safely into a river. It remains very unusual for accidents to be caused by pilots failing to deal with bad weather at high altitudes. The International Civil Aviation Organization (ICAO) says that more than half of all accidents between 2006-2011 were runway safety-related. Although bad weather is often involved in aircraft accidents, the reality is that by itself, a terrible storm usually won t be the reason for an aviation accident.


This is partly because bad weather is predictable meteorological devices are designed to see storms brewing and potential risks for flight. This is also partly because airplanes and helicopters are designed to withstand severe weather. So when a plane or helicopter crashes, it was usually due to someone s negligence. For example, even if aircraft can be operated in certain weather conditions, still, pilots and crews must perform necessary precautionary measures in order to accommodate them, such as in flight de-icing ice building up on the wings and plane is common during flight; but not taking the necessary steps to de-ice the plane could cause a plane to crash. Being able to identify the negligent party is the first step to helping you start to recover.
