Thanks Krusty, that explains it.
Hmmm that petty pedantic failing of people sounds like a damn poor way to run a C & T dept and a damn good way to piss off crews.
I thought the aim was to ensure a flt dept and crews that can work in a realistic, professional fashion in the real world and maintain a very high level of safety whilst doing it.
Hmmm then again maybe I'm not being realistic.
