Narrative:
Received a 'low altitude' alert from ric ATC while on VOR/DME approach to runway 15 at chesterfield county airport, va (fci). I was at 2100 ft MSL as published on the standard instrument approach procedure (nopt) from flat rock VORTAC. Richmond radar stated that their system would given a 'low altitude' alert if the aircraft was below 2600 ft MSL (ie, required for procedure turn entry). Procedure was completed, as published. Errors: 1) either the standard instrument approach procedure for the VOR/DME runway 15 approach at fci is published incorrectly, or 2) the ric ATC radar software for 'low altitude' alert was misprogrammed, or 3) I don't know how to read. Callback conversation with approach control facility at ric revealed the following information: controller states that a low altitude alert warning is not a common occurrence on this approach. He states that if an aircraft is slightly left (north) of course, the low altitude alert is possible. He references the antenna on the final approach course as the cause of such an alert.

Title: BE58 RECEIVES LOW ALT ALERT ON APCH TO FCI.
Narrative: RECEIVED A 'LOW ALT' ALERT FROM RIC ATC WHILE ON VOR/DME APCH TO RWY 15 AT CHESTERFIELD COUNTY ARPT, VA (FCI). I WAS AT 2100 FT MSL AS PUBLISHED ON THE STANDARD INST APCH PROC (NOPT) FROM FLAT ROCK VORTAC. RICHMOND RADAR STATED THAT THEIR SYS WOULD GIVEN A 'LOW ALT' ALERT IF THE ACFT WAS BELOW 2600 FT MSL (IE, REQUIRED FOR PROC TURN ENTRY). PROC WAS COMPLETED, AS PUBLISHED. ERRORS: 1) EITHER THE STANDARD INST APCH PROC FOR THE VOR/DME RWY 15 APCH AT FCI IS PUBLISHED INCORRECTLY, OR 2) THE RIC ATC RADAR SOFTWARE FOR 'LOW ALT' ALERT WAS MISPROGRAMMED, OR 3) I DON'T KNOW HOW TO READ. CALLBACK CONVERSATION WITH APCH CTL FACILITY AT RIC REVEALED THE FOLLOWING INFO: CTLR STATES THAT A LOW ALT ALERT WARNING IS NOT A COMMON OCCURRENCE ON THIS APCH. HE STATES THAT IF AN ACFT IS SLIGHTLY L (N) OF COURSE, THE LOW ALT ALERT IS POSSIBLE. HE REFS THE ANTENNA ON THE FINAL APCH COURSE AS THE CAUSE OF SUCH AN ALERT.
