Happy if I helped. I flew that type many long moons ago. Definitely the old technology but never had any problem with ice while flying it.

Can't help re the Dash 7. Judging by your training advice, I guess it has the newer technology deicing boot. Suggest you discuss this further with your TRI if you need better understanding.
Sorry Hew
Our posts crossed, wasn't ignoring you. Can't provide what you ask. Can state quite categorically that I have actually seen ice accretion where the boot has been inflating underneath a bridged layer without separation from the leading edge (saw it on the ground after landing when we broke it off) and found the bridged area in the ice which was consistent with the inflated boot shape and not the leading edge.
