Icing is some serious ****, but it does not occur in a few seconds of some light clouds blowing past you when otherwise flying in clear weather.
Maybe not seconds but just a few short minutes!
Was shooting a approach, on top of cloud and began our descent, at 2500' we entered the weather the 332 icing system had to be placed on Force mode at 1000'. Took all the pitch to level off at 400' for the landing!
Airframe was completed engulfed in rime!
Yes, can occur very very fast!😎
