Maybe an alternative would be for the CAA to cross-reference how often pilots access the AIS site vs how many hours they claim to fly. If you don't log in for two years, you presumably haven't flown during those two years....so, voila your licence is revoked! [Takes cover under nearest rock....]
So if you use a computer where a user has already logged in (such as at many flying clubs, or flying schools), you would have your licence revoked?
What utter rubbish.
