Complete loss of radar for approximately 5 mi. No primary, no beacon, no ARTS tag. This problem has occurred time and time again. I am not aware of anyone doing anything to correct it. Callback conversation with reporter revealed the following information: reporter states that radar tracking problem is frequent to aircraft transitioning from fay approach control to clt approach control, 7000 ft and below. The track loss is an area 15 mi either side of fay clt boundry. As soon as clt accepts a handoff from fay, the ARTS track will display 'CST,' then drop from the tracked target. The ARTS track will again 'autoacquire' when the aircraft is well in clt airspace. The reporter advised that this area used to be a documented non-radar transition area until fay moved their radar site towards the clt boundary. The reporter advises that this is a heavily traveled route between the two metropolitan areas.

Title: CLT CTLR CONCERNED WITH AREA SPECIFIC RADAR COVERAGE.
Narrative: COMPLETE LOSS OF RADAR FOR APPROX 5 MI. NO PRIMARY, NO BEACON, NO ARTS TAG. THIS PROB HAS OCCURRED TIME AND TIME AGAIN. I AM NOT AWARE OF ANYONE DOING ANYTHING TO CORRECT IT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT RADAR TRACKING PROB IS FREQUENT TO ACFT TRANSITIONING FROM FAY APCH CTL TO CLT APCH CTL, 7000 FT AND BELOW. THE TRACK LOSS IS AN AREA 15 MI EITHER SIDE OF FAY CLT BOUNDRY. AS SOON AS CLT ACCEPTS A HDOF FROM FAY, THE ARTS TRACK WILL DISPLAY 'CST,' THEN DROP FROM THE TRACKED TARGET. THE ARTS TRACK WILL AGAIN 'AUTOACQUIRE' WHEN THE ACFT IS WELL IN CLT AIRSPACE. THE RPTR ADVISED THAT THIS AREA USED TO BE A DOCUMENTED NON-RADAR TRANSITION AREA UNTIL FAY MOVED THEIR RADAR SITE TOWARDS THE CLT BOUNDARY. THE RPTR ADVISES THAT THIS IS A HEAVILY TRAVELED RTE BTWN THE TWO METROPOLITAN AREAS.
