Narrative:
This was a military funded cap mission sortie hayward to duluth to ashland to hayward to do a line search with SID to side deviations as called for by the 2 observers in the plane. As the ceiling was scattered to broken at about 4000', I filed an IFR flight plan and placed 'cap search' in the remarks. I am a qualified cap command pilot and believed that this cleared me to deviate side to side as I flew direct between fixes. The ZMP controller questioned these deviations from direct, so I stopped them and completed the line search with centered CDI. In trying to figure out what was wrong so I could correct it, I believe I should probably tell the controller each time I deviate even when it is only by 1 or 2 degrees either side. Also, since we work a lot with ord, I should have realized that msp might have a different understanding of our procedures.

Title: PVT ACFT ON CIVIL AIR PATROL FLT FILES AN IFR PLAN, BUT DEVIATES FROM ONE SIDE OF COURSE TO THE OTHER WITHOUT PERMISSION FROM ATC.
Narrative: THIS WAS A MIL FUNDED CAP MISSION SORTIE HAYWARD TO DULUTH TO ASHLAND TO HAYWARD TO DO A LINE SEARCH WITH SID TO SIDE DEVIATIONS AS CALLED FOR BY THE 2 OBSERVERS IN THE PLANE. AS THE CEILING WAS SCATTERED TO BROKEN AT ABOUT 4000', I FILED AN IFR FLT PLAN AND PLACED 'CAP SEARCH' IN THE REMARKS. I AM A QUALIFIED CAP COMMAND PLT AND BELIEVED THAT THIS CLRED ME TO DEVIATE SIDE TO SIDE AS I FLEW DIRECT BTWN FIXES. THE ZMP CTLR QUESTIONED THESE DEVIATIONS FROM DIRECT, SO I STOPPED THEM AND COMPLETED THE LINE SEARCH WITH CENTERED CDI. IN TRYING TO FIGURE OUT WHAT WAS WRONG SO I COULD CORRECT IT, I BELIEVE I SHOULD PROBABLY TELL THE CTLR EACH TIME I DEVIATE EVEN WHEN IT IS ONLY BY 1 OR 2 DEGS EITHER SIDE. ALSO, SINCE WE WORK A LOT WITH ORD, I SHOULD HAVE REALIZED THAT MSP MIGHT HAVE A DIFFERENT UNDERSTANDING OF OUR PROCS.
