all pilots accept the AIP published numbers as gospel and will not drill down any further
Surely the Aerodrome Manual is the
de facto source of information? I know that RAF Northolt has one of the first Defence Aerodrome Manuals (on the open internet) and I seem to remember seeing the arrester beds with pictures under the RESA section.
Also, I've flown into civil aerodromes with obstacles within the approach/take off surfaces and the CAA have issued an exemption (as described in their Aerodrome Manual) for them. The aerodrome still being licenced with this exemption.
