Aircraft Accidents due to weather phenomenons

An aviation accident is defined as an occurrence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, in which a person is fatally or seriously injured, the aircraft sustains damage or

structural failure or the aircraft is missing or is completely inaccessible.

- 21.3% of total accidents are weather realted.

- 76% of Causes of NAS delays in 2004 is weather realated.

different weather phenomenons that may cause aircraft accidents: 1-Fog 2-volcano 3-lightnings 4-thunders 5-microbursts 6-rain/snow 7-sandstorms...

 During taxiing, the weather deteriorated and low-lying clouds limited the visual range to about 300 m (1,000 ft). Legal or stipulated threshold for takeoff was 700 m (2,300 ft) visibility

everything is calm until suddenly out of nowhere the pilot says:"Goddamn, that son-of-a-bitch is coming straight at us!"

The ash is hard and abrasive and can quickly cause:1- significant wear on propellers and turbo compressor blades 2-scratch the cockpit windows3-impairing visibility4-It contaminates fuel and water systems, can jam gears5-can cause a flameout of the engines

Volcanic ashes:

although all the four engines were off, there were no fatalities.

failure of all four engines. 

The aircraft was able to glide far enough to exit the ash cloud
