surface surveillance
It is not a REQUIREMENT to have surface movement surveillance systems in order to carry out CAT II and CAT III operations, or indeed, low visibility take-offs.
Each airline is required to audit the airport to determine if the risk is acceptable.
The ground operations are "procedural" and not visual.
Just as a matter of interest, the international standard for location of the light filter change from Green/Yellow to Green only as you come off the runway is in the wrong place for procedural control of aircraft. Therefore, in very low visibility conditions, when the pilot reports runway vacated, the aircraft is in about the worst location for localiser interference. Just thought I would remind you, as you all know this one! The error is also in CAP 168 for those of you who think that the UK is immune from this type of thing. Safety by compliance with a bad standard is still gross negligence!
