It's still not clear (to me) how you update the PF3 database... With PF3 you MUST run the MakeRwys utility
I run MakeRwys if there have been any changes at all to my addon airports (or after a sim update), otherwise the data in the runways.csv file will be exactly the same as the last time I updated the PF3 database. I had already checked the runways.csv file - that has VOVZ too, not VEVZ (maybe if it had VEVZ instead, PF3 would stop having this problem??). Running MakeRwys.exe before updating the PF3 database makes no difference to this little issue anyway (as one would expect) - I tested it. The new runways.csv file still shows VOVZ, not VEVZ.
It doesn't matter if an ICAO is changed in the RW, PF3 only knows what is in the simulator, via MakeRwys. There's no way to change this in PF3, you would have to change it in the sim.
... as I say, MakeRwys has VOVZ... and I have changed everything in the sim - it's all up to date with the new ICAO.
My guess is the file containing the ICAO code in question is in the PF3FSXData.dat file, which you cannot change with a text editor
Maybe: as you say Dave, I cannot check that.
Please attach your flight plan so I can see if it works here
OK
Sorry, this is getting a bit more long-winded than I had anticipated. Bottom line is I cannot use the proper ICAO code for Visakhapatnam Airport without PF3 crashing. Not exactly a deal-breaker of course. It would be satisfying though to get to the bottom of why PF3 is still reporting that it cannot find 'VEVZ' (and why it is even looking for it); but if you're busy, or getting fed up with this topic now, don't worry too much about it Dave!
