Ah Mr 'P'..... I thought you HAD retired.......
Well, consider the first publication of CTAFs and MBZs.....Waaay back in '91 was it?
Or was that one of the '93 'improvements' ?
I can't remember no more.....
MBZs....15nm rad., up to and inc. 5,000ft AGL......
CTAFs.... 5nm rad., up to and inc. 3,000ft AGL......
So theeeere we all were, the 'bugsmashers' amongst us that is,
looking at the ELEVATION of those various aerodromes, and adding the appropriate 'AGL' to get the 'ALT' thru which we would pass thru or over....
'Tis still a crock........
