Narrative:

Advised tower route of flight before departure. Departed and flew runway heading. At 100' AGL, I directed my scan to the instruments and began flying the aircraft solely by reference to instruments. My instrument was the safety pilot. At 300' AGL, I heard the tower tell another aircraft what our direction of flight would be. In order not to be a conflict to the other traffic, I started turning at standard rate. I came within 150' vertical and 500' horizontal of a building. There never was a common understanding between my instrument and myself. He thought I was flying the aircraft VFR until I asked him for the hood and put it on, when in reality I was flying the aircraft solely by reference to instruments. The instrument did not take prompt control of the aircraft, nor tell me to avoid it by turning the other direction. It may help if the aim printed some text to help instrs/students have a common understanding. I should have told the instrument that I was initiating instrument scan.

Title: GA SMA TURNED TOO CLOSE TO A BUILDING ON PRACTICE IFR DEP FROM DPA.

Narrative: ADVISED TWR ROUTE OF FLT BEFORE DEP. DEPARTED AND FLEW RWY HDG. AT 100' AGL, I DIRECTED MY SCAN TO THE INSTRUMENTS AND BEGAN FLYING THE ACFT SOLELY BY REF TO INSTRUMENTS. MY INSTR WAS THE SAFETY PLT. AT 300' AGL, I HEARD THE TWR TELL ANOTHER ACFT WHAT OUR DIRECTION OF FLT WOULD BE. IN ORDER NOT TO BE A CONFLICT TO THE OTHER TFC, I STARTED TURNING AT STANDARD RATE. I CAME WITHIN 150' VERT AND 500' HORIZ OF A BUILDING. THERE NEVER WAS A COMMON UNDERSTANDING BTWN MY INSTR AND MYSELF. HE THOUGHT I WAS FLYING THE ACFT VFR UNTIL I ASKED HIM FOR THE HOOD AND PUT IT ON, WHEN IN REALITY I WAS FLYING THE ACFT SOLELY BY REF TO INSTRUMENTS. THE INSTR DID NOT TAKE PROMPT CONTROL OF THE ACFT, NOR TELL ME TO AVOID IT BY TURNING THE OTHER DIRECTION. IT MAY HELP IF THE AIM PRINTED SOME TEXT TO HELP INSTRS/STUDENTS HAVE A COMMON UNDERSTANDING. I SHOULD HAVE TOLD THE INSTR THAT I WAS INITIATING INSTRUMENT SCAN.
