Agree this is very educational/informative. It's ironic how the PDF memo cougar found starts after SWA's GPWS issues at BHM...
As far as precedence between the 8260 and the JO 6850...the memo and 8260 repeatedly point out that below MDA on non-precision IAPs, penetration of TERPS OCS isn't implied or guaranteed...hence the visual nav via PAPIs (in this case) with their TCH and PAPI OCS ensuring safe/clear passage to landing.
Since JO 6850 gets into PAPI OCS and TCH specs very deep, I'd think that once an IAP mandates the use of VGSIs (in this case at night), below MDA, 6850 takes precedence.
Side note: In PAPI construction/implementation, TCH setting comes first via the chart I posted from the JO, then PAPI angle/placement and OCS are tweaked in compliance with the TCH from step a. See 503.a - c of JO
USMC, as far as my search goes...I'm not looking for ones an A300 would go into so much as ones ANY HG4 aircraft would go into. I think by throwing those other parameters into the search, the haystack of possible runways is small. BHM is the only needle I've found, but the search continues nonetheless.
