Procedure; Human Factors
I was directed to cross COUPS Intersection at or above 2;000 FT and cleared for the RNAV GPS Runway 2 approach to SAC. I was further directed that if I went missed approach to fly the published missed approach and to contact the Approach Controller on same frequency. After getting established on the approach I was directed to contact SAC Tower. Upon contacting the Tower; the Controller instructed me that upon reaching the missed approach altitude; I was to make my turn before reaching the approach end of the runway. I acknowledged the instruction; checked my chart and saw that the initial missed approach instruction was to climb to 3;000 FT direct HOGBI. According to my GPS; HOGBI was a heading of 019 degrees; directly the same as the final approach course. So; no turn would be required. I thought that odd; but didn't question it as I continued the approach and looked outside to try and resolve a traffic alert call out at same altitude two o'clock. In retrospect; I should have asked the Tower Controller for clarification; as the instruction to turn at the MAP was confusing. I continued the approach; and then at 500 FT; I called missed approach to the Tower and commenced to climb. The Tower Controller said for me to start my turn. I asked 'What turn? HOGBI is straight ahead.' He shouted that I was to turn immediately! He gave no assigned heading; so I turned right to a heading of 150; then told him I had been assigned to fly the published missed approach and asked what was up? He said that the published miss is not allowed and that I should have been assigned alternate missed approach instructions by the Approach Controller. He said he would call the Controller directly to clear it up. I was then told to switch to NorCal. Checking in with the Approach Controller; I told him my heading and altitude; then asked about the missed approach instructions; confirmed that I had been told to fly the published missed. He concurred and said I had not made a mistake and would not receive a violation. I then cancelled IFR and proceeded directly to LVK for landing.
A General Aviation pilot; on a RNAV GPS Runway 2 approach into SAC; was confused by the Tower's missed approach instructions given. They were contrary to the instructions issued by NCT TRACON.
