Mode S in STN Zone - or not?

[fireflybob]

Anyone knows what this means and why it's been published?

I think they are saying you do not need mode S in the Stansted TMZ so long as you have mode A/C.

Thanks for any help

Exactly as you say.

However, they only issued this as the previous one ran out, and the LAA amongst others were concerned at the foot dragging. There is a line of thought this is to be compatible with the R112 stuff, and post Sept 12 it will not be renewed i.e. you might need Mode S after that...
