Sqawk7700,
Have you ever been to India? Where else can you be on final and be told by ATC to go around due "Visibility below minima"? You tell him you have the whole airport and runway in sight, but "Negative, visibility below minima, Go around! I'm not talking about shallow fog here.
Or you sit at the gate, "negative start up, RVR 300 meters". But we can see from the gate and almost to the end of the runway, so it's at least 2000 meters? "Negative, RVR 300 meters, negative start up!"
It's not about Swiss cheeses, it's about plain stupidity! And it's about procedures you'll only find in India.
Tks SPD33bd, I had a good laugh when I read you Calcutta story.
