CAT is mostly, but not necessarily, found on the cold side and in the area of narrow bends of a jet stream. You might ride a jet without the slightest shake but all the same encounter CAT in almost calm wind conditions.
The most important action after flying the aircraft is to try and get out of the turbulent area (climb/descend), unless its obviously temporal. Speed control is essential when penetrating turbulent conditions for two reasons:
To cover possible wind shear (keep speed away from V
mo or M
mo)
to expose the airframe to as little stress as possible
But CAT doesn't have to include rapid changes in wind component. You can get it with changes of wind direction as low as 10° and no change in wind speed at all...
Its danger is in the first place the stress it exerts on the airframe and the cleaning costs for the cabin afterwards
