Human Factors
The jumpseater was slow to return to the cockpit. While descending through 10;000ft I cycled the seat belt switch several times and hailed to him over the intercom. The jumpseater had mentioned that he had been on [another aircraft] for a while and I felt like he would be up any second; so I continued the arrival. Once we started to configure; I tried the seatbelt bell and intercom again. I called the tower at approximately 1;000ft and informed the controller that we needed to take a turn in the pattern to get a passenger in their seat. She approved a right 360 and we were still cleared to land. I made a climbing right turn and we raised the gear and raised the flaps to 28. Once we were stable at 2;000 ft AGL; while asking the First officer (FO) to go check on the jumpseater; the doorbell rang and the jumpseater returned to the cockpit. We continued the right turn and re-configured for landing. We were fully stable and re-established on the Loc and Glide slope for our visual approach before 500ft but the FMS had not caught up with us and the FMS speed ball was still in the go around position at approximately 210kts. We bow tied 165kts which was about 10kts above the lower foot. I felt like it was ok to continue and the landing and rollout were uneventful.
Captain of a large turbojet reported an issue with an Observer Crew Member who did not return to their designated seat in time for landing. Captain elected to do a go-around.
