I hear the Akrotiri eng det is being actively considered when the state exemptions for Mode "S" run out next March. Surely, it makes more sense to fit TCAS to large multi-aircraft? With all the world's air forces operating in Afg airspace and carrier group aircraft on top, it would appear to me to be essential. If the paperwork is not already in, might be worth submitting it. I will try and raise this issue via PQs.
It would be interesting to find out the implications of Nimrod being banned from entering European airspace.
Apologies Spanners, but this issue has been raised with me privately. I will now revert to thread.
