Narrative:

My mishap took place at orlando executive airport (orl) in florida. The aircraft is a C550. The WX was day VMC. Broken clouds around 7000 ft MSL. Our clearance was soaps 1 radar vectors to intercept J53 to craig (crg) then direct destination. The soaps 1 departure reads: all aircraft maintain 1500 ft. Expect radar vectors to filed/assigned route. Expect clearance to filed altitude 10 mins after departure. The departure specific routing off of runway 7 reads: turn left heading 025 degrees to intercept orl 045 degree radial. Unless otherwise assigned, departure control frequency use 119.775. The aircraft I fly has primus 1000 avionics with a GNS-xls FMS. After receiving our clearance and before leaving the chocks I set up my avionics as follows: heading bug was set to 025 degrees. Course selector was set to 045 degrees and orl frequency of 112.2 was set in both navigation #1 and #2. I set up the FMS for the follow on routing on J53. J53 is a course of 355 degrees off of orl to crg. I then set up the FMS with the routing and selected the leg from orl to barbs, which is the first intersection on J53. Taxi to runway 7 from the FBO was very short. While running the taxi checklist, I selected FMS on my display controller. Usually at our home base we get vectored to our filed routing, so this is common practice. However, in this case it set my CDI to the J53 course of 355 degrees instead of the departure course of 045 degrees. Since we were lightweight for takeoff, we climbed to 1500 ft quickly and I had to level off and turn to 025 degree heading around the end of the runway. We received the frequency change and were radar idented. Shortly after, we were given a climb to 3000 ft. Upon leaving 1500 ft we were given a new altitude of 5000 ft. Then we received the next control frequency and made the change. Upon check in, the controller gave us an amended altitude of 3000 ft. During this time the copilot was busy changing frequencys and altitude preset, I was still on a 025 degree heading. I noticed that the heading was not going to allow us to intercept the course and told that to my copilot. He looked at the departure again and said it's supposed to be the 045 degree radial. I tried to turn my course selector to 045 degrees, but it would not move my course needle. That's when I realized that I had the FMS selected. I deselected FMS, reset my course selector to 045 degrees and turned to intercept the course. However, by this time we had been flying heading 025 degrees for about 4 mins and were mi north of the required course. As soon as I made my turn to the east to correct, the controller gave me a 360 degree heading to fly. On that heading I flew over orlando sanford airport (sfb) and then was given a heading of 320 degrees to intercept J53 and a climb to a higher altitude. The cause of the mishap was simple. I set the avionics appropriately for the departure while in the chocks, but selected the wrong navigation source during taxi. I don't remember selecting FMS during the taxi, but since that's when I normally select it, I must have done it out of habit.

Title: C550 CREW HAD A TRACK DEV AFTER NOT SETTING THE FLT GUIDANCE SYS PROPERLY.

Narrative: MY MISHAP TOOK PLACE AT ORLANDO EXECUTIVE ARPT (ORL) IN FLORIDA. THE ACFT IS A C550. THE WX WAS DAY VMC. BROKEN CLOUDS AROUND 7000 FT MSL. OUR CLRNC WAS SOAPS 1 RADAR VECTORS TO INTERCEPT J53 TO CRAIG (CRG) THEN DIRECT DEST. THE SOAPS 1 DEP READS: ALL ACFT MAINTAIN 1500 FT. EXPECT RADAR VECTORS TO FILED/ASSIGNED RTE. EXPECT CLRNC TO FILED ALT 10 MINS AFTER DEP. THE DEP SPECIFIC ROUTING OFF OF RWY 7 READS: TURN L HDG 025 DEGS TO INTERCEPT ORL 045 DEG RADIAL. UNLESS OTHERWISE ASSIGNED, DEP CTL FREQ USE 119.775. THE ACFT I FLY HAS PRIMUS 1000 AVIONICS WITH A GNS-XLS FMS. AFTER RECEIVING OUR CLRNC AND BEFORE LEAVING THE CHOCKS I SET UP MY AVIONICS AS FOLLOWS: HDG BUG WAS SET TO 025 DEGS. COURSE SELECTOR WAS SET TO 045 DEGS AND ORL FREQ OF 112.2 WAS SET IN BOTH NAV #1 AND #2. I SET UP THE FMS FOR THE FOLLOW ON ROUTING ON J53. J53 IS A COURSE OF 355 DEGS OFF OF ORL TO CRG. I THEN SET UP THE FMS WITH THE ROUTING AND SELECTED THE LEG FROM ORL TO BARBS, WHICH IS THE FIRST INTXN ON J53. TAXI TO RWY 7 FROM THE FBO WAS VERY SHORT. WHILE RUNNING THE TAXI CHKLIST, I SELECTED FMS ON MY DISPLAY CTLR. USUALLY AT OUR HOME BASE WE GET VECTORED TO OUR FILED ROUTING, SO THIS IS COMMON PRACTICE. HOWEVER, IN THIS CASE IT SET MY CDI TO THE J53 COURSE OF 355 DEGS INSTEAD OF THE DEP COURSE OF 045 DEGS. SINCE WE WERE LIGHTWEIGHT FOR TKOF, WE CLBED TO 1500 FT QUICKLY AND I HAD TO LEVEL OFF AND TURN TO 025 DEG HDG AROUND THE END OF THE RWY. WE RECEIVED THE FREQ CHANGE AND WERE RADAR IDENTED. SHORTLY AFTER, WE WERE GIVEN A CLB TO 3000 FT. UPON LEAVING 1500 FT WE WERE GIVEN A NEW ALT OF 5000 FT. THEN WE RECEIVED THE NEXT CTL FREQ AND MADE THE CHANGE. UPON CHK IN, THE CTLR GAVE US AN AMENDED ALT OF 3000 FT. DURING THIS TIME THE COPLT WAS BUSY CHANGING FREQS AND ALT PRESET, I WAS STILL ON A 025 DEG HDG. I NOTICED THAT THE HDG WAS NOT GOING TO ALLOW US TO INTERCEPT THE COURSE AND TOLD THAT TO MY COPLT. HE LOOKED AT THE DEP AGAIN AND SAID IT'S SUPPOSED TO BE THE 045 DEG RADIAL. I TRIED TO TURN MY COURSE SELECTOR TO 045 DEGS, BUT IT WOULD NOT MOVE MY COURSE NEEDLE. THAT'S WHEN I REALIZED THAT I HAD THE FMS SELECTED. I DESELECTED FMS, RESET MY COURSE SELECTOR TO 045 DEGS AND TURNED TO INTERCEPT THE COURSE. HOWEVER, BY THIS TIME WE HAD BEEN FLYING HDG 025 DEGS FOR ABOUT 4 MINS AND WERE MI N OF THE REQUIRED COURSE. AS SOON AS I MADE MY TURN TO THE E TO CORRECT, THE CTLR GAVE ME A 360 DEG HDG TO FLY. ON THAT HDG I FLEW OVER ORLANDO SANFORD ARPT (SFB) AND THEN WAS GIVEN A HDG OF 320 DEGS TO INTERCEPT J53 AND A CLB TO A HIGHER ALT. THE CAUSE OF THE MISHAP WAS SIMPLE. I SET THE AVIONICS APPROPRIATELY FOR THE DEP WHILE IN THE CHOCKS, BUT SELECTED THE WRONG NAV SOURCE DURING TAXI. I DON'T REMEMBER SELECTING FMS DURING THE TAXI, BUT SINCE THAT'S WHEN I NORMALLY SELECT IT, I MUST HAVE DONE IT OUT OF HABIT.
