For single pilot ops I think it's fair to say that only lip-service is paid to CRM in the UK. Why don't we re-name it "airmanship" and then we know it applies to everyone?
Anyway, in the absence of crewroom chat and feedback I believe that CRM courses are good value if well designed. Anything that can highlight the perils inherent in go/ no go decision making be it judgement of weather or acceptance of technical defects and commercial pressure has to be a benefit.
Reading "Collective's" post was instructive! (Been there too as a baby co-pilot)Single pilots will do the same sort of thing but there is usually no one around to know about it.
