Narrative:
Encountered wake turbulence resulting in an abrupt 2-5 degree uncommanded roll. Departing passenger commented about it. ZTL jams it as close as they can -- guess they'll stop when they kill someone. Callback conversation with reporter revealed the following information: the reporter has been surveying the actions of his company and ATC. It is alleged that the company actually is 'working with' ATC in trying to accomplish an increased capacity at atl because that airport produces a lot of revenue for the air carrier. The average distance between aircraft is between 2-3 mi, with 2 being more the norm than 3. He feels that he can't, as a pilot, do much while on approach other than try to increase his separation by reducing airspeed. On the ground he is trying to change policy.

Title: AN ARRIVING B727 PIC COMPLAINS OF THE TEMPORARY LOSS OF ACFT CTL WHEN ENCOUNTERING THE WAKE TURB OF A PRECEDING B727.
Narrative: ENCOUNTERED WAKE TURB RESULTING IN AN ABRUPT 2-5 DEG UNCOMMANDED ROLL. DEPARTING PAX COMMENTED ABOUT IT. ZTL JAMS IT AS CLOSE AS THEY CAN -- GUESS THEY'LL STOP WHEN THEY KILL SOMEONE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR HAS BEEN SURVEYING THE ACTIONS OF HIS COMPANY AND ATC. IT IS ALLEGED THAT THE COMPANY ACTUALLY IS 'WORKING WITH' ATC IN TRYING TO ACCOMPLISH AN INCREASED CAPACITY AT ATL BECAUSE THAT ARPT PRODUCES A LOT OF REVENUE FOR THE ACR. THE AVERAGE DISTANCE BTWN ACFT IS BTWN 2-3 MI, WITH 2 BEING MORE THE NORM THAN 3. HE FEELS THAT HE CAN'T, AS A PLT, DO MUCH WHILE ON APCH OTHER THAN TRY TO INCREASE HIS SEPARATION BY REDUCING AIRSPD. ON THE GND HE IS TRYING TO CHANGE POLICY.
