Gulfcapt:
I can't recall whether this data has been posted yet or not; sorry if its a repeat.
From the Jepp 10-9 Airport/Info dated 24 Feb 06: Runway 30 right-hand circuit.
From the Jepp 11-1 ILS DME Rwy 30 dated 23 May 03: No restrictions shown for circling pattern. Straight in mins of 1965' (309')/800m with ALS. Circling mins at 135 kts of 2410' (742')/1600m and 180 kts of 2510' (842')/2400m.
There is the prohibited area due south of the airport, plus a note on the 11-1 to avoid overflight of the city south and west. Certainly casts doubt on the right-hand circuit.
We have discussed the CTL protected area a lot, and have used the premise of 205 knots, MDA 2,150, because that is in fact the protected airspace the ill-fated flight had, whether the airplane was Approach Category C or D.
I have all the current Jepps for the airport. Because the "right circuit to Runway 12" note is on the airport diagram page, I took it (and take it) to be a VFR operations advisory. Because the weather was less than VFR the CTL charted minimums would, to me at least, take precedence over an "airport manager's preferences." Had the state aviation authority concurred, it would have not authorized unrestricted circling.
