Thanks, Bookworm. I've never visited anywhere else that uses Class D, and that was the root of my point. Most places (i.e. overseas) that I've visited seem to think that we (UK) are something of an anomaly - I apologize if I'm posting someone's opinion rather than fact!. .. .Are you sure about the Dutch? I was under the impression that all Dutch CTRs were Class C for civil or E for military. I'm pretty sure that Schiphol is Class C CTR. In fact my post was partly based on comments by a tower supervisor there whom I bumped into recently.. .. .Do you think that the EU will try to impose a standard across Europe (perhaps as JAR gathers pace)?. .. .Do you know of anywhere that has instrument approaches but no controlled airspace outside the UK?. . . . <small>[ 30 March 2002, 08:11: Message edited by: 1261 ]</small>
