Also whats this talk of ELT requirements in Belgium/Holland?
Well, duh, it's a requirement. In Holland at least. Mode-S too, above 1200' AGL.
For mode-S, refer to the AIP of the Netherlands, specifically:
GEN 1.5, para 4
ENR 1.6, para 2
There's also a few AICs about this, available from
AIS Netherlands or the Eurocontrol site.
For ELT, it's actually an ICAO requirement (annex 6 amd. 31), made applicable in Dutch law as of Feb. 1st, 2009, and is applicable to all international flights in the Dutch FIR. Refer to AIC-B 07/08 for details:
