Hercules rapid decent due to icing
One of the techies we work with down here in the SW heard that a Hercules, (EGY 1525), had to make a rapid descent, from around FL200, this morning due to flying through a rather cool patch of air.
Since we recorded a balmy 9 degrees at our transmitter site, which is high, I presume they flew through the upper layer of the next icy blast of air we're going to get any time soon.
Is this weather causing similar problems for the jet jockeys also?
No sensationalism requested. Thanx.
