BEagle:
I hold a NPPL (SSEA/SEP) which required revalidation by the 19th Dec 2007. In accordance with AIC 3/2004 para 1.3.1 (a), at the end of October 2007 I undertook a 1 hour instruction flight with an instructor who signed my 1 hour PUT logbook entry. At that time I had flown 30 hours as PIC in the previous 12 months.
As a result of the changes you listed in your initial post, what am I required to do between now and the end of April 2009 to maintain my license validation?
By the way, I didn't find the 1 hour instruction flight particularly onerous. An independent check every two years that you can still perform the exercises you were taught when first learning to fly (e.g. PFL, stall recovery, steep turns, etc) keeps you from getting 'rusty', and the cost, using my aircraft and fuel, was only £20.
