Thanks for the 're-kindle' Keith - back in to point out that the 'min vis' of 1200m would almost certainly be tied to the appropriate approach angle/MDH/MDA, and as food for thought, would it not be a moot point if the actual vis was 1000m but the runway was in sight? What are the chances of a 'fog bank' obscuring the runway below 1000' in those conditions? Also, in which direction was the met vis 'observed'? I recall sitting drinking coffee at RAF Cranwell
'in the fog' waiting for the airfield to become flyable, when the met man rubbed the condensation off the met office window....
I still believe we are placed in the cockpit to make SENSIBLE AND SAFE decisions and my view would be that the debrief should revolve around 'discussion' rather than 'bollock'. Of course, this POV does not logically extend to lower DH/DA's for, say, an ILS, but for a NPA..?
