Thank you Crab - I couldn't remember if we had limits except for snow and icing! And serviceability of coffee boiler of course (joke - it never went u/s)
ps just in case DB thinks you never go IMC because of the day/night trg limit of "CCISS" you'd better explain FCS procedures, RADOPS, modified transitions, AHT etc.......I had to explain all that to various green 78 Sqn types, oh, and the Irish Government, who couldn't understand why their shiny new Dauphin's didn't seem to work
