Kevster,
Your name sounds familiar from the wannabbe side.....
....anyway enough idle bantar.....
.....I went to NATS selection tests in Bournemouth about a year and a half ago. I remember a very long personality questionnaire. These are basic questions and you just have to answer them truthfully. I also remember there was a paper of questions on the info. they sent me. These were like "What is secondary radar?" and "What is the standard vertical separation standard above FL 290?" etc.. There were also questions on spatial awareness, but no tests on a PC the day I went.......however things may have chamnged in the past 18 months and my memory is getting rusty........
Ciao!
