Hi Foggy, Single to Multi Crew transition is not that easy, I have seen guys struggle with this before, it's hard to call for things to be done rather than do it yourself, the idea of communication-action sounds too long winded and it seems really kack handed initially, (strewth, it would be easier if I did it myself).
In terms of briefings, I would suggest the list you have offered come under SOPs, if you brief a pilot what they already know then all you accomplish is the 'Wall of Sound' effect and nothing goes in. We found this particularly in the FW world and while not attempting to say 'We do it better' (we don't in many cases), the style we find most useful is 'Brief the Threats': This is an NDB/DME approach Rwy 27, the inbound course is offset by 7 degrees, we are expecting to see a runway in our 11 o'clock with PAPIs on the left hand side. There is a parallel taxiway on the right and I will do my best to avoid landing on it. Big mountain to the west and the sector safe is xx. Expecting icing conditions etc, etc.
As a brief 'patter' we use CTWO for take off and CTWOF for landing.
C Charts - not the whole gruesome detail, just an outline with the relevant items.
T Terrain - where is it and how high.
W Weather - is it marginal, CAVOK, any windshear.
O Operational - use of anti ice, wx radar etc.
F Fuel - only relevant for landing since you want to know how long you have to stooge around and where you go if you can't get in.
Regards
