Reproducable FMC error.

[NoobX 4]

Hi guys,

 

Doing my last flight from OMDB to VHHH my sim' crashed due to an unknown problem...

 

After the crash, I started to mind about what would crated it. GUESS WHAT? I think I've found.

 

To reproduce it you have to:

1. Be in flight or ground doesn't matter. Wherever in the world.
2. Put VHHH as arrival
3. Select the SIERA1G arrival
4. ILS25R
5. Transition TD

Then you'll have to try to remove the GO AROUND procedure.

When you'll try to remove the LKC and/or (LKC-4) points your FMC will "freeze" the route.

 

CONSEQUENCES:

1. The points arn't deleted.
2. You cannot edit the FMC route in any way (no WPT insertion, Delete, etc...)
3. You'll not be able to select another SID/STAR

I took a brief look to the topic about FMC VAS LEAK but I think it's not the same....

 

Anyone else could identify this?

Hope PMDG can take a deeper look to this.

 

Best regards, Bruno Teixeira.

One of the problems I see is the SIERA1G STAR is for an RNAV arrival.  For an ILS arrival it would be the SIERA6B STAR.

 

I'm into VHHH a lot and have never had any problems with this arrival.

most likely  issue  is  nav  data  is  corrupt

I'd advise against trying to delete the missed approach procedure using the CDU. Best if you edited the sidstar file.  For example, VHHH ILS25R:

 

APPROACH ILS25R FIX RIVER 4500 FIX FI25R 1290 RNW 25R FIX OVERFLY D253C AT OR ABOVE 430 TURN RIGHT DIRECT FIX LKC 4000 SPEED 185 TRK 073 UNTIL 4.0 FROM FIX LKC FIX TD 5000 HOLD AT FIX TD RIGHT TURN INBOUNDCOURSE 343 LEGTIME 1

 

Becomes simply:

 

APPROACH ILS25R FIX RIVER 4500 FIX FI25R 1290 RNW 25R

 

Just delete everything after the RNW 25R keywords... I've also flow both VHHH 25L/R approaches from KDFW without issue but if you wish to modify the approach do it in the sidstar file.
