My UK PPL is due in late Nov 2012. Will it be possible to have it revalidated on an EASA aircraft?
Huh?
Do you mean that the SEP Class Rating included in your PPL is due for revalidation in late Nov 2012, or that your UK-issued JAR-FCL PPL(A) is due for re-issue then? A 'UK PPL' is a lifetime licence, as will be an EASA part-FCL PPL(A) - but a JAR-FCL PPL(A) has to be re-issued every 5 years.
