Narrative:

I was on an IFR flight plan flying into pdk. Atl approach handed me off to pdk tower, 5 mi out on the GPS runway 27 approach, which I was flying hooded with an instructor for an ipc. WX was VFR. Tower asked me to report left downwind for runway 20L. I took off the hood. At this point, I was approaching the field from the east on the final approach heading 277 degrees. I elected to level off at pattern altitude 2000 ft MSL and not the 1500 ft for GPS runway 27. As I rolled out from my right turn to the left downwind for runway 20L, a C172 crossed my flight path from right to left at pattern altitude. There was no time to take evasive action. Immediately I queried the tower about other traffic and got the reply that I was #1 to land on runway 20L. This was a very close call inside the class D, and the airport did not seem to be very busy at the time. I think there was no excuse for the tower not calling traffic conflicts. If we had been called 5-10 seconds earlier, there would not have been an near midair collision. I believe I was 1/2 mi east of the runway 2R/20R at the time of the incident.

Title: UPON ENTERING THE RWY 20 TFC PATTERN AT PDK OFF THE GPS RWY 27 APCH, A C182 IFR TRAINING FLT HAS AN NMAC WITH A C172. RPTR ALLEGES NO TA GIVEN.

Narrative: I WAS ON AN IFR FLT PLAN FLYING INTO PDK. ATL APCH HANDED ME OFF TO PDK TWR, 5 MI OUT ON THE GPS RWY 27 APCH, WHICH I WAS FLYING HOODED WITH AN INSTRUCTOR FOR AN IPC. WX WAS VFR. TWR ASKED ME TO RPT L DOWNWIND FOR RWY 20L. I TOOK OFF THE HOOD. AT THIS POINT, I WAS APCHING THE FIELD FROM THE E ON THE FINAL APCH HDG 277 DEGS. I ELECTED TO LEVEL OFF AT PATTERN ALT 2000 FT MSL AND NOT THE 1500 FT FOR GPS RWY 27. AS I ROLLED OUT FROM MY R TURN TO THE L DOWNWIND FOR RWY 20L, A C172 CROSSED MY FLT PATH FROM R TO L AT PATTERN ALT. THERE WAS NO TIME TO TAKE EVASIVE ACTION. IMMEDIATELY I QUERIED THE TWR ABOUT OTHER TFC AND GOT THE REPLY THAT I WAS #1 TO LAND ON RWY 20L. THIS WAS A VERY CLOSE CALL INSIDE THE CLASS D, AND THE ARPT DID NOT SEEM TO BE VERY BUSY AT THE TIME. I THINK THERE WAS NO EXCUSE FOR THE TWR NOT CALLING TFC CONFLICTS. IF WE HAD BEEN CALLED 5-10 SECONDS EARLIER, THERE WOULD NOT HAVE BEEN AN NMAC. I BELIEVE I WAS 1/2 MI E OF THE RWY 2R/20R AT THE TIME OF THE INCIDENT.
