I will try and do something later...... but the thing about the published missed approach is that it is often superceded by the deconflicting headings and levels that are needed to separate the go-around and departure.

As for the 3000ft transit - that would put you into the LTMA Class A CAS of course - and you can't only fly IFR there - so not only the zone but the LTMA would need changing.

Slim - you would be amazed at the lack of rate of climb! Wait for a hot day, with a wind NE and sit at OCK at 2.4A. See how the A340s scrape the zone at 2900/3000ft. (Some have A340s have kept 160kts until about 20nm into the SID to get a better ROC)

Mike - good point - I will get it drawn on.

I don't think that the FOS-CHT route would work - as all Northolt departures climb and maintain 3000ft initially. (there is no room to climb them early)

Any suggestions on Westerlies then?

OK - here\'s a thought:



If you either got rid of the SW corner (OCK-WOD) or made it Class D - it would help Farnborough out as they have a lot of traffic squeezed into the ILS area. (also little uses it and little environmental impact)

The zone to the E & W is 12nm from LHR. At the 8nm point to the WEST - make it Class D up to 1000ft or possibly 1500ft - allowing traffic to route BUR-ASCOT as they do now (at the moment of course we cannot have opposite direction traffic there)

All this would be fairly easy to implement.

Any other ideas?!?!!
