Gents,
Getting awfully tired of "who's paying better" and "who forged what licences" discussions...I still read them avidly. Just though I'd throw this one out there for a bit of a fresh discussion.
I'm currently flying Seahawks for the RAN and used to fly for the USN (same acft type). If our blade de-ice (main and tail rotor), windscreen de-ice, or engine anti ice is not functional, we are limited to temperatures above +5degC in visible moisture. If we've got all the functional de-ice and anti-ice kit, we can operate down to +1degC in visible moisture.
Anyone else want to weigh in with their aircraft types and similar limitations? Stories of terrifying ice build up

and 'derring do'

in escaping to tell the tale?
Except for one instance of snow flakes coming out of the air conditioning ducts at 10,000' in Southern California, I've been extremely lucky on the icing front.
