Heston,
While your reference is correct, it is also wrong.
One can revalidate an NPPLMicrolight RATING with just 60 minutes on a microlight.........
If one is also revalidating a SSEA rating and you have the required 11 hours on that.
Of course, the reverse i true and you can Reval an SSEA ratting on an NPPL with just one hour on an SSEA, if you have a micro rating and the 11 hours on that.
Now you can Reval as micro in the second 12 months, but an SSEA seems to be in the last three months!
What a crock of pooh.
As an examiner, I just try to make sense and sighn what I think ius best and easiest for the pilot.
To be frank, no one knows _ and no one cares.
