Hi Tubby, no we don't operate the bus any differently but to be honest the bluey/green book would not be worth having unless you have a copy of our OMA or FCOM. I see you are an ATPL on big busses so the info in it will be familiar to you. It is mostly theoretical stuff on weather, icing etc. Anything that needs a definite figure ie holdover times has a reference to either our OMA or FCOM. The only thing spelled out longhand is the decode for a Snowtam/Rwy State Decode which I am sure you have.
The winter brief has been getting thinner for a couple of years and as an uncontrolled document I don't think the management want it used without reference to the OMA/FCOM.
Sorry to be so unhelpful, to all those that have requested a copy I applaude your conscientiousness and desire for information but I am afraid we probably cannot help. As has been stated already the best people to ask our your own Ops Depts, I would hope that they would make all efforts to produce a guide, that way you will be bulletproof on that dark, cold snowy night.
