Is TCAS II required for RVSM?

[erj-145mech]

And now the government and industry are working on TCAS IV, which will give RA for horizontal traffic too, not just vertical traffic.

, but if you were to go to Europe for example, where they have full blown RVSM, it would in fact, be required. Is this accurate or have I misinformed? Please reference a source on the net if posible, so I can collect on my steak dinner. Thanks

Question P1: Do I require ACAS/TCAS to operate in RVSM airspace?
Answer: The carriage and operation of ACAS/TCAS is not an RVSM requirement. However, the ICAO Regional Supplementary Procedures for Europe (Doc 7030/4) require that ACAS II be carried and operated in the European Region by all civil, fixed-wing turbine-engined aircraft having a maximum take-off mass exceeding 5700 kg or a maximum approved passenger seating configuration of more than 19.

2. Airborne Collision Avoidance System II (ACAS II). (TCAS II, Version 7.0 meets the ICAO ACAS II standard).
(a) U.S. operators flying in airspace where RVSM is applied must comply with Part 91 Appendix G (Operations in RVSM Airspace). Appendix G states that unless otherwise authorized by the FAA, aircraft equipped with TCAS II and used in RVSM operations must incorporate Version 7.0 or a later version. For operations within other countries,
Part 91 Section 91.703 requires U.S. operators to "…comply with the regulations relating to flight and maneuver of aircraft there in force".(b) Non-U.S. Operators should confirm ACAS II equipage requirements applicable to them with the responsible State authority. Many countries have adopted the ICAO Annex 6, Part I (International Commercial Air Transport Airplanes) standard: from 1 January 2005, turbine-engined airplanes with a maximum certificated take-off mass in excess of 5,700 kg or authorized to carry more than 19 passengers shall be equipped with ACAS II.

I like steak too.

Didn't you mean to say the RA's displayed in the cockpit will be able to give instructions for maneuvering in the horizontal plane as well as in the vertical plane for resolving the RA?

Thanks for the heads up(to me at least) re: the shelving of TCAS III in favor of TCAS IV.
