Okay, now this is in the twilight zone.
I turn on the autopilot and autothrottle... It lights up but that is ALL it does.
It does not work at all, in other words I have full control of either control and the autopilot does nada.

I mean, minus the lights on the autopilot panel I still have full control like the autopilot was disengaged.
I tried the Z key to see if there was an internal AP failure, however that wasn't the case :S

So it does seem like either we have to transplant an AP system from a different aircraft or most likely contact Captain Sim's support...
