Well, Using one of my most recently familiar airfields..
Currently at Kemble, what with the increased activity due Brize "moving" to Fairford, procedures exist when there are ILS/PAR inbounds to Fairford on Rwy09, the extended centreline of which routes through Kemble's Overhead approx 1/2 mile north of the main Rwy.
When this is the case, the ATZ height drops to 1000' QFE and No Ohj's permitted, just Straight in's (offset due NA) or downwind/base/crosswind joins.
All this information is passed over the RTS, with no prior knowledge expected from visiting pilots. Apart from the noise abatement, which im sure everybody reads!
