Default Can they fail the FMS too?

More things to make you scratch your head.

Last year during recurrent, I was handflying while the Capt was trying to build a short notice hold. We got to the fix before it was in the machine, so I did a direct entry. The guy running the sim, stopped us and asked what I had done. He then proceeded to show us what the Bus would have done with the same solution. We were just a little behind everyone else who had done the scenario ahead of us--i.e. they all had it built and coupled to the AP before they got to the fix, I was just AP and basic heading mode. What he had been used to seeing was a turn to parallel, eventhough it violated the AIM and the AF way of doing things. Turns out, I hate to admit, it made a prettier pattern when viewed from above. It didn't go to far to the non manuevering side, and rolled out inside the course on the manuevering side and corrected back with only a twenty degree intercept. The pattern he played back from what I had done doing it the correct by the AIM method showed us making a nearly 250 degree turn as we were right on the line for the direct technique/procedure and our outbound leg was very close to the inbound course, so when I turned inbound, it overshot and was a greater distance on the non manuevering side than what the FMS had done when it did a parallel. Makes you wonder.....
