Narrative:

I was cleared for the VOR-23 approach at mbs, and established on the final approach course inbound. This was a practice approach under VFR/VMC with qualified safety pilot on board. Tower asked my intentions after the VOR-23, and I replied I wanted the ILS-23 to a full stop. At this point I was at MDA (1220) and 2 mi final on the VOR-23. Tower said I was 'cleared for the option', and gave me a new heading (320) and altitude (2400). I then turned to 320 and initiated a climb. Tower asked my heading, and I replied 320. Tower said I should still be on the final approach course inbound, and told me to continue 320 vectors to ILS-23. I realized immediately that even though this was a 'practice' approach under VFR, I must still complete the approach all the way to the map (in this case, mbs VOR on field).

Title: DEVIATION FROM CLRNC. SMA PLT ON PRACTICE APCH MAKES MISSED APCH PRIOR TO MISSED APCH POINT.

Narrative: I WAS CLRED FOR THE VOR-23 APCH AT MBS, AND ESTABLISHED ON THE FINAL APCH COURSE INBND. THIS WAS A PRACTICE APCH UNDER VFR/VMC WITH QUALIFIED SAFETY PLT ON BOARD. TWR ASKED MY INTENTIONS AFTER THE VOR-23, AND I REPLIED I WANTED THE ILS-23 TO A FULL STOP. AT THIS POINT I WAS AT MDA (1220) AND 2 MI FINAL ON THE VOR-23. TWR SAID I WAS 'CLRED FOR THE OPTION', AND GAVE ME A NEW HDG (320) AND ALT (2400). I THEN TURNED TO 320 AND INITIATED A CLIMB. TWR ASKED MY HDG, AND I REPLIED 320. TWR SAID I SHOULD STILL BE ON THE FINAL APCH COURSE INBND, AND TOLD ME TO CONTINUE 320 VECTORS TO ILS-23. I REALIZED IMMEDIATELY THAT EVEN THOUGH THIS WAS A 'PRACTICE' APCH UNDER VFR, I MUST STILL COMPLETE THE APCH ALL THE WAY TO THE MAP (IN THIS CASE, MBS VOR ON FIELD).
