Narrative:

While training, I mis-idented runway on radio causing aircraft #2 to enter pattern for runway 14. I was actually taking off of runway 32 and C172 was on downwind 14. After takeoff, I made left turnout as C172 began a left base to runway 14. I reported a left crosswind for runway 14, and C172 reported he saw only an aircraft on crosswind for runway 32. Aircraft were well clear of each other, but the potential was there. I had WX diverted to the airfield and was unfamiliar. Proper review of airfield diagrams and a simple compass check have been re-emphasized.

Narrative: WHILE TRAINING, I MIS-IDENTED RWY ON RADIO CAUSING ACFT #2 TO ENTER PATTERN FOR RWY 14. I WAS ACTUALLY TAKING OFF OF RWY 32 AND C172 WAS ON DOWNWIND 14. AFTER TKOF, I MADE L TURNOUT AS C172 BEGAN A L BASE TO RWY 14. I RPTED A L XWIND FOR RWY 14, AND C172 RPTED HE SAW ONLY AN ACFT ON XWIND FOR RWY 32. ACFT WERE WELL CLR OF EACH OTHER, BUT THE POTENTIAL WAS THERE. I HAD WX DIVERTED TO THE AIRFIELD AND WAS UNFAMILIAR. PROPER REVIEW OF AIRFIELD DIAGRAMS AND A SIMPLE COMPASS CHK HAVE BEEN RE-EMPHASIZED.
