I suspect you will be no rustier in a years time than you are now if you have not flown for 9 months or so. I have a question - I have not had to go through the revalidation process as I have had my JAR IR/ME less than a year - but why does it cost so much to do it. By my reckoning 1500 quid is 5 hours - is this a typical amount of time needed or would it be less if you retain reasonable proficiency. Also is there a fee like the initial IR for a revalidation and who can do it?. .If anyone can shed light on the matter I would be most appreciative.
