Low level turbulence and icing fog
WebTurbulence areas Areas with turbulence - including cloud turbulence (except in connection with convective clouds), Low Level Turbulence (LLT) and Clear Air Turbulence (CAT) - are delimited by a blue dashed line; further details are given in „WARNINGS AND/OR REMARKS“. WebDefinition Fog comprised of supercooled water droplets which normally deposit rime ice on contact with an object with a surface temperature of less than 0°C. Fog is generally defined in terms of visibility being less than 1000m horizontally and freezing fog typically forms in the temperature range of -0°C to -20°C. Freezing fog is reported as FZFG on a …

Wind shear across the boundaries of the jet will need corrective action on the part of the pilot. In concrete terms, the low-level jet implies that terrain clearance may be compromised, and difficulties during the landing phase may be encountered.

One of the two conditions for structural icing to form is the aircraft must be flying through visible … WebIcing. Icing, in general, is any deposit or coating of ice on an object, caused by the impingement and freezing of liquid (usually supercooled) hydrometeors; to be distinguished from hoarfrost in that the latter results from the deposition of water vapor. Factors which affect the icing threat include: Particle size; Particle concentration
