Narrative:
I filed an IFR flight plan rnt-pdx. My clearance was: cleared to pdx V23 btg direct, maintain 10000', expect 11000' 20 NM south of sea. After departure make a right turn around to 350 degrees, contact sea departure 119.2 I forget to squawk. After departure I executed a right turn around to 350 degrees. For whatever reason I construed the term 'around' to mean a 360 degree turn. The assigned heading was only 20 degrees to the right. Sea departure advised me of my track southbound, and I acknowledged and advised him I was turning to the right to a heading of 350 degrees, no problems arose from the confusion. However, I feel it could have been a conflict. I suggest tower personnel when observing IFR departures ensure aircraft are following presented clrncs as it applies to departure headings. Pilot should clarify any ambiguity.

Title: PLT OF SMA DEPARTING RWY WITH HEADING OF 330 DEGREES WAS CLEARED TO TURN AROUND TO HEADING OF 350 DEGREES. PLT COMPLIED WITH A 360 DEGREE PLUS TURN TO GET TO 350 DEGREES.
Narrative: I FILED AN IFR FLT PLAN RNT-PDX. MY CLRNC WAS: CLRED TO PDX V23 BTG DIRECT, MAINTAIN 10000', EXPECT 11000' 20 NM S OF SEA. AFTER DEP MAKE A RIGHT TURN AROUND TO 350 DEGS, CONTACT SEA DEP 119.2 I FORGET TO SQUAWK. AFTER DEP I EXECUTED A RIGHT TURN AROUND TO 350 DEGS. FOR WHATEVER REASON I CONSTRUED THE TERM 'AROUND' TO MEAN A 360 DEG TURN. THE ASSIGNED HDG WAS ONLY 20 DEGS TO THE RIGHT. SEA DEP ADVISED ME OF MY TRACK SBND, AND I ACKNOWLEDGED AND ADVISED HIM I WAS TURNING TO THE RIGHT TO A HDG OF 350 DEGS, NO PROBS AROSE FROM THE CONFUSION. HOWEVER, I FEEL IT COULD HAVE BEEN A CONFLICT. I SUGGEST TWR PERSONNEL WHEN OBSERVING IFR DEPS ENSURE ACFT ARE FOLLOWING PRESENTED CLRNCS AS IT APPLIES TO DEP HDGS. PLT SHOULD CLARIFY ANY AMBIGUITY.
