Dual FMC failure - Freeze during flight

Recommended Posts

Hi everybody,

 

Maybe it is a bug from FSX, but when I simulate a dual FMC failure in cruise and I use the ALTN LEG page to go direct to a point or a fix with coordinates, the sim freeze and go out to windows.

 

Is anybody has the same issue ?

 

Thanks,

Vincent

Actually it sounds similar to one problem i had with freezes and using the FMC. The solution was to modify the FSX.cfg to have [JOBSCHEDULER]

AffinityMask=14

 

and then i reinstalled all the directX and Visual C+ runtimes.

Good call - didn't even think of that. Thanks!

Hi,

 

Thanks for the replies.

 

I think also that re)installing everything without looking for the trouble is insane.

 

So, this is what I tried :

 

Set AffinityMask=14 STILL FREEZING

Set AffinityMask=14 + Re-install DirectX and Visual C+, still freezing STILL FREEZING

Flying with 1 FMC only and entering a direct to coordinates OK

Flying with 2 FMCs failure and entering a direct to coordinates STILL FREEZING

 

Any other ideas ?

 

Thank anyway, I hope it will help for the P3d version.

 

Cheers,

Vincent

Submit a ticket at the link above. There might be something that's been seen before, and if not, tracking can be started on it.

Are you entering the coordinates in the correct format?

(it shouldnt crash things....but still)

 

What happens if you go direct to a waypoint that is still in the CDU?

(the FMC flight plan should be continuously copied and update to the CDUs so that when both FMC fail you still have your complete original route in the CDU for what is called alternate navigation).

This made me think, some freezes i was having were initially caused by an out of data airac for navdata, inputting some waypoints caused a subsequent freeze around 30 seconds later if the database didn't recognise them.
