Hi,

 

I have recently begun having problems with sporadic, uncommanded flap deployments on both the PMDG 777 and the NGX.  The problem is likely on my end, but I am curious if anyone else has encountered this, or has suggestions on troubleshooting it.  Here is a summary of what I am experiencing:

 

1. After certain keystrokes ([open ATC window] and [pause simulation]), the flaps will fully extend.  This does not happen consistently every time I used these keystrokes, but only sometimes.  However, every time that it has occurred, it has been immediately after I have executed one or the other of these keystrokes.  This has happened multiple times on both aircraft.  So far, I have been unable to duplicate the problem using FSX default aircraft, or other add-ons, but I have not had the time to text extensively enough to verify whether they are affected too.  As I said, the problem is sporadic to it is difficult to verify.

 

2. The problem has happened both on the ground and in flight.

 

3.  The problem began recently, shortly after I installed Active Sky Next for the 7-day trial.  However, I doubt that this is related, since I have had it happen a couple of times when ASN was not running.  I did post the issue in their support forums, but they said they have not seen this before.

 

4. I had been using the default keyboard commands for these actions (' for ATC window and "p" for pause).  I later tried remapping these commands to other keystrokes, but strangely, the problem continued with the newly assigned keystrokes; this is when I really began to feel stumped.

 

I know I could always just reinstall FSX, but I hate going that route unless I absolutely have to.  Any ideas would be appreciated.

Hi! Try This: Run the pmdg ngx and 777 installers again. You already have them installed, so it should ask if you want to remove or repair. repair it, and try a full flight. Hopefully it'll work for you =)

You might take a look at the keystroke areas in the CDU setup. You may have some conflicts between FSX assignments and FSUIPC, if you're running the purchased version. It sounds more like poltergeist at work though. Raziz has a good suggestion for performing the exorcism.

Thank you! i think before any hard things that you have to do, try my suggestion first. if i doesn't work, try Rick's.

Thanks for the tip raziz.  I tried your idea, but without any success; the problem still persisted.  Next I dug into RIck's idea, and came up with the idea of completely deleting the "extend flaps fully" command from FSX, since it is not a command I have much use for anyway.  To my surprise, this got rid of the problem.  Not sure what was causing in the first place, but clearly some software was issuing the F8 flap extension command.  Anyway problem solved.  Thanks for the support.
