LVPs - ooh scary stuff - particularly at dodgy regional airports that won't spend money on ground radar. I wouldn't like to be in the tower on a foggy day, giving take-off and landing clearances with your fingers crossed. I mean how many pilots get lost in LVPs ? And what is ATC separation based on ? Pilots knowing where they are. Wasn't there a case at GLA of aircraft taxing up one of the links onto the runway in LVPs ?
