Narrative:

On takeoff out of napa county (apc), I climbed out on runway heading off of runway 36L. We were not assigned any SID. The IFR clearance that I had received from ground had cleared us to sgd VOR. On departure, I maintained runway heading until checking in with departure. The center controller then asked us if we were in our turn. I immediately started the left turn to sgd VOR. We were asked to call center. When I did, the controller very politely asked if I was familiar with the departure procedure. I told him that I wasn't. He told me that we needed to start the turn to sgd by 1 mi. I hadn't realized that. I later looked at the published SID for that runway (lizard departure) and it spelled out the procedure. I looked at the instrument departure on the commercial airport diagram and realized that I had overlooked the note clearing the aircraft on course after takeoff. The controller cleared the airspace for us. He said he wasn't going to file a deviation. Although I did miss the turn on course off of the standard IFR departure procedure, I feel it could have been avoided if I had been assigned the lizard departure. It made the importance of the turn easily seen. It would be best to assign the SID no matter the meteorological conditions.

Title: CREW CLBED RWY HDG INSTEAD OF MAKING A L TURN ON COURSE.

Narrative: ON TKOF OUT OF NAPA COUNTY (APC), I CLBED OUT ON RWY HDG OFF OF RWY 36L. WE WERE NOT ASSIGNED ANY SID. THE IFR CLRNC THAT I HAD RECEIVED FROM GND HAD CLRED US TO SGD VOR. ON DEP, I MAINTAINED RWY HDG UNTIL CHKING IN WITH DEP. THE CTR CTLR THEN ASKED US IF WE WERE IN OUR TURN. I IMMEDIATELY STARTED THE L TURN TO SGD VOR. WE WERE ASKED TO CALL CTR. WHEN I DID, THE CTLR VERY POLITELY ASKED IF I WAS FAMILIAR WITH THE DEP PROC. I TOLD HIM THAT I WASN'T. HE TOLD ME THAT WE NEEDED TO START THE TURN TO SGD BY 1 MI. I HADN'T REALIZED THAT. I LATER LOOKED AT THE PUBLISHED SID FOR THAT RWY (LIZARD DEP) AND IT SPELLED OUT THE PROC. I LOOKED AT THE INST DEP ON THE COMMERCIAL ARPT DIAGRAM AND REALIZED THAT I HAD OVERLOOKED THE NOTE CLRING THE ACFT ON COURSE AFTER TKOF. THE CTLR CLRED THE AIRSPACE FOR US. HE SAID HE WASN'T GOING TO FILE A DEV. ALTHOUGH I DID MISS THE TURN ON COURSE OFF OF THE STANDARD IFR DEP PROC, I FEEL IT COULD HAVE BEEN AVOIDED IF I HAD BEEN ASSIGNED THE LIZARD DEP. IT MADE THE IMPORTANCE OF THE TURN EASILY SEEN. IT WOULD BE BEST TO ASSIGN THE SID NO MATTER THE METEOROLOGICAL CONDITIONS.
