Mode S and ADS-B stuff

An interesting article in the latest Flight International:
Quote " Air traffic control surveillance using automatic dependent surveillance - broadcast as a sole means has been approved by EASA."

Goes on to mention that only a small fleet of "pioneer airlines" is suitably equipped to benefit from this etc etc.

Then says "This is the first operational - rather than trial - clearance for ADS-B use in Europe and represents the first step in a programme that will see aircraft and ANSP equipage with 1090MHz ADS-B extended squitter become mandatory by 2015".

Is this likely to affect us and the Mode-S requirement/debate?

Most mode s transponders provide the extended squitter which EASA plan to use for ADS-B. The CAA outlined a three phase approach to aircraft interoperability. Phase three was ADS-B using Mode s extended squitter. There was no timeframe for Phase 3 but if you plan to fit mode s make sure you fit one with extended squitter or my guess is you will have to replace it again. If you look up the minutes from the CAA meetings at LAA HQ you will get more detail.

5 months after the Mode S consultation ended, and no word from the CAA.

Has anyone heard anything ?
