I think you are being a little hard on A310. I agree with him that just because some others are deicing does not mean I'm going to also. It sure will alert me to the fact that deice MAY be needed but after inspection and satisfied that the wings are clean it will be a cold day in **** that I deice just because everyone else is doing it. I'm paid to make those decisions regarding the safety of MY aircraft.
The example being set is that there are a lot of variables involved and that one has to stay on top of the situation to make a safe decision. I have climbed on top of many a ladder to personally verify the condition of the wing instead of staying in my warm cockpit and saying lets go get sprayed just in case. I hope the FO's ARE learning from that example.
