Narrative:

As the approach control facility bordering atl approach on the southwest corner, it falls to us at csg approach to sequence turboprop aircraft landing at atl when atl is on an east operation (runway 8R/left and runway 9R/left). The letter of agreement between atl and csg dictates that aircraft will be cleared to atl via V222, V241 direct or by radar vectors to tiroe and then via the atl 228 degree right. All aircraft must enter atl airspace through a gate which includes V222 and V241 and some space on each side. All high performance turboprop aircraft shall be cleared to cross 40 DME southwest of atl at or below 10000' and cross tiroe at 8000'. At tiroe the floor of the TCA is 8000', however this floor extends only about 6 mi south of tiroe along V241 and about 7 1/2 mi southwest along V222. The floor beyond those points is 10000'. This TCA confign and letter of agreement ensures that 1 of 2 things will occur. Either 1) the aircraft will enter the TCA where the floor is 1000' and will then descend out of the TCA and reenter through the side where the floor is 8000', or 2) the aircraft will descend below 10000' prior to entering the TCA and will operate below the floor prior to entering the side of the 8000' floor area. Both of these situations violate far 91.90 and FAA order 7110.65F paragraph 7/97. Also, nobody at my facility has ever been trained to advise aircraft that they are leaving the TCA as they descend below it.

Title: TCA ENTRY EXIT REQUIREMENTS ARE NOT BEING ADHERED TO PROPERLY.

Narrative: AS THE APCH CTL FAC BORDERING ATL APCH ON THE SW CORNER, IT FALLS TO US AT CSG APCH TO SEQUENCE TURBOPROP ACFT LNDG AT ATL WHEN ATL IS ON AN E OPERATION (RWY 8R/L AND RWY 9R/L). THE LETTER OF AGREEMENT BTWN ATL AND CSG DICTATES THAT ACFT WILL BE CLRED TO ATL VIA V222, V241 DIRECT OR BY RADAR VECTORS TO TIROE AND THEN VIA THE ATL 228 DEG R. ALL ACFT MUST ENTER ATL AIRSPACE THROUGH A GATE WHICH INCLUDES V222 AND V241 AND SOME SPACE ON EACH SIDE. ALL HIGH PERFORMANCE TURBOPROP ACFT SHALL BE CLRED TO CROSS 40 DME SW OF ATL AT OR BELOW 10000' AND CROSS TIROE AT 8000'. AT TIROE THE FLOOR OF THE TCA IS 8000', HOWEVER THIS FLOOR EXTENDS ONLY ABOUT 6 MI S OF TIROE ALONG V241 AND ABOUT 7 1/2 MI SW ALONG V222. THE FLOOR BEYOND THOSE POINTS IS 10000'. THIS TCA CONFIGN AND LETTER OF AGREEMENT ENSURES THAT 1 OF 2 THINGS WILL OCCUR. EITHER 1) THE ACFT WILL ENTER THE TCA WHERE THE FLOOR IS 1000' AND WILL THEN DSND OUT OF THE TCA AND REENTER THROUGH THE SIDE WHERE THE FLOOR IS 8000', OR 2) THE ACFT WILL DSND BELOW 10000' PRIOR TO ENTERING THE TCA AND WILL OPERATE BELOW THE FLOOR PRIOR TO ENTERING THE SIDE OF THE 8000' FLOOR AREA. BOTH OF THESE SITUATIONS VIOLATE FAR 91.90 AND FAA ORDER 7110.65F PARAGRAPH 7/97. ALSO, NOBODY AT MY FAC HAS EVER BEEN TRAINED TO ADVISE ACFT THAT THEY ARE LEAVING THE TCA AS THEY DSND BELOW IT.
