Definition

Reports relating to accidents and serious incidents which involved weather or related atmospheric conditions as a significant causal factor.

The reports are grouped together below in subcategories. Weather related events are mostly related to the occurrence or risk of a loss of control because of the effects of significant in flight icing or in flight turbulence. The turbulence case can involve en route or low level flight, the latter especially in respect of approach and landing. Many adverse weather events are associated with Cumulonimbus (Cb) cloud or phenomena associated with them such as the occurrence of Hail, Microbursts or Tornados.
