I'm booked in for Stage 1 in London on 18th March (afternoon session).
I just got out the Duke book from the Library (Ed. 9) and it's awful - so many inconsistencies (and I'm only on the 2nd chapter) and a few things that are just plain wrong! (example: the year that Swanwick opened is different on pages 4 and 12; page 41 makes a note that the word "to" is not used with flight levels, yet the example immediately before does use it...) I hope it's not used as a standard text to be tested on.
The info document that NATS link to in the email is a bit out of date as well - Terminal Control moved to Swanwick a year ago and West Drayton no longer exists...
Oh well, we'll see what happens!
