Our company removed the SOP to call "visual - runway lights" or similar. My theory was that on a CATIII if you call visual at 100ft, then the RHS relaxes too much and expects a "land" call at 50ft but by then the LHS has lost visual causing a bit of confusion and maybe coming into the realms of confirmation bias. Or possibly the RHS assumes that if LHS says "visual" he would take control, again causing confusion. Am I right? Any more experienced guys have any ideas?
