I was in much the same situation as you (less the 5000 hours unfortunately).
I obtained a PPL back in 1967, but due to circumstances had never been able to keep it valid for more than a couple of years, so it was more than 30 years out of date.
The SRG have a GID (18? - see the SRG web site) which gives all the rules. They make a distinction of 0-5 years, 5-10 years and more than 10 years.
I had to:
- take
all the written exams
- take the R/T licence exam
- gain at least 10 hours of flying, which covered
* 2 hours spin/stall awareness
* at least 4 hours solo
* at least 4 hours cross country, including the qualifying cross country
- take the skill test
In all, I took about 25 hours to regain the licence. Lots of sweat and tears boning up for the written though - not used to it nowadays.
I now have a JAR PPL
