Thanks for all your advice, I'm feeling more relaxed already.
Although I think I'm going to buy one of these cheap mini TCAS systems used in General Aviation once I have my PPL and CPL. Anyone considered this? Around £500, any advice on the TCAS system at Transair? Or the Monroy ATD-200?
The scariest aspect of closing in on an aircraft is not knowing whether or not the other guy as seen you.
And I figure because gliders are climbing fast and flying aerobactics, the "relative constant bearing" is virtually non existent and you cannot predict where they will be next!
