With no disrespect intended I wont tell you how to drive your radar blips if you dont tel me how to fly my approach. Looking out a window in the tower and looking out of the flight deck on approach are two totaly different things and viewed from different positions. Regardless of the RVR I can start the approach and go as far as the OM. If the RVR at the OM is below minima I have to go around if its not I can continue. If after the OM it dips below minimum I can continue to dDH and make up my own mind. As a pilot I am used to and trained to fly to minima and execute a go-around if I have to, are you able to make that decision? There is also a distinct difference between RVR and reported met visibility.
Can I look at 2 blips on a screen and decide if they will be a conflict in 2 mins time? Do I know all your rules and regs? Probably not
