See the last AIP plate for Heliport (18 October 2012) identifies St. Georges tower at 322 ft, not actual 594 ft today.
Appreciate there are NOTAMs updating figures, nevertheless, that tower has grown a lot since October. AIP details often take say three or more months to be updated.
Whose responsibility is it to monitor rising building heights and feed data through CAA system such that they appear correctly in AIP (and swiftly)? Who would give CAA the update on current building height?
