Black knight,
There is already a record of the flying habits for all of us - a personal log book. The CAA can see it any time they want to.
Who would monitor our flying habits and how would it help? I presume you mean for anti-terrorist reasons. I am uncertain how and what it would achieve. It would require a database of every pilot or wannabe (pilot or terrorist?) worldwide. A mammoth task for nowt, I think.
Perhaps all pilots should be electronically tagged instead <img src="wink.gif" border="0">
