Narrative:

An aircraft is on final to any runway at dtw within 1 mi of the runway. If an aircraft on the ground has its transponder on, the conflict alert feature of the ARTS 3A alarms. This causes data blocks to appear on the BRITE radar and block crucial data. This could lead to problems. Callback conversation with reporter revealed the following information: facility operations manager stated management was aware of the problem and the facility had regional office approval to install a patch in the ARTS program which will solve the problem.
