Yep - skills test it is then. Hey ho - it'll doubtless improve my flying, so not all bad!
The thing that got me is that the licence was issued on 31/03/06 (I took a while to get round to getting the medical), but the SEP rating was back dated to the date I passed the skills test - 16/11/05.
I mistakenly thought I had until March and was getting ready to get all revalidated in Jan/Feb.
Whoops! Oh well - how much is a skills test running at these days?
