A Control Zone classification change from Class D to Class C transponder mode C required) will enable more effective and efficient provision of air traffic control (ATC) services at the London Airport.

This change will take effect March 12, 2009 at 09:01 Coordinated Time Universal Time (UTC). The appropriate aeronautical publications will be amended.

Official announcement …

The blogosphere has been pretty quiet as of late. I’m planning a post on cold weather and how it affects the altimeter.

I noticed yesterday that my site search is broken (most likely from the movable type upgrade I did). I couldn’t get it fixed yesterday, so its still broken. It returns all pages regardless if your search term appears in it or not.

I’ll let you know when it’s fixed.
