Hi Chasing767
I don't have a problem with believing your story because I've been there, done that, scared myself ****less. Lucky me, the cricket and the shaker went off when we were about 2-3 inches above concrete so I had no time to botch up the landing. We have also set speed bugs according to normal speeed schedule, picked up some light ice during the descent and when we turned anti- and de-icing off, decided to wait with icing AoA reset till the ice melts - you already know that we forgot to do that.
I don't know how approach speeds are set on E170 but I'll assume they're set automatically by FMS. If I guessed it correctly, it would be easy to install system similar to ATR's (ice evidence probe and manual confirmation that airplane is clear of ice), connected to FMS so as long as icing AoA is on, FMS sets higher speeds and as soon as it's reset, bugs go down.
It's all very well to have some extra knots when you have ice on the plane but those extra knots over threshold turn into extra runway used for stopping. No big deal if you land on 2500m+ of tarmac, but if your destination is not blessed with long runway, these extra knots might adversely affect your payload.
Cheers, C.
