The required visibility was 1200 metres. The actual visibility was 1000 metres by the ATIS. There was no RVR requirements given on the approach plate, only vis. I continued the approach to the approach ban point then became visual with the ground and the airport environs so continued the approach. Would that be considered legal?
I would say it isnt legal. Visual doesnt come into it where approach ban is concerned. Its whatever the reported visibility is at the time. Quite often you can actually see the runway and the whole airport when vis is as low as 200m but you cant make an approach unless the vis comes upto or above your required minima. Very frustrating when your circling overhead !!
