Is SMR an airport requirement for operating CAT III approaches?
If not then why has Delhi international published a NOTAM saying CAT III is un-available due to no SMR? :confused:
Replies appreciated.

Not in the UK it isn't, but I wouldn't like to do it without. :eek:

SMR is a requirement in lots of airports in order to offer cat III approaches.

Haven't got SMR at Bristol yet but we've operated very successfully and safely with a Cat 3B ILS on Rw27 since late 2001: the low vis procedures used by ATC are quite restrictive accordingly, in facilitating the maximum sustainable movement rate of just 4 aircraft (3 northside, 1 southside). These have a degree of belt-and-braces built-in, such as use of "follow-me" vehicles to lead aircraft from intermediate stop-bars to stands and to confirm position of aircraft at Cat 3 ILS runway holding point stop-bars. Not sure if the aircrew appreciate just how restrictive this all becomes for ATC, mind, given the very congested ramp layout...SMR will be welcome!

I think with RVR below 350 m it is mandatory or at least recommended by ICAO to use SMR for operations in Low Visibility/CAT III

It is not a requirement in the UK.

I stand to be corrected, but as I recall, some years ago, CAA SRG mandated the provision of SMR at airfields operating to CAT3, but oddly, placed no time limit on when those airfields who didn't already have it, should get it by.

That begs the question then if an airport has SMR and Cat II/III operations what happens if the SMR is unserviceable? In our case, nothing (except that the movement rate would be lower).
We too have procedures in place to operate in LVPs without the SMR.

RVR below 350m + SMR u/s = NO movements!
