Ron,
Another Dave here, but not the intelligent one that wrote the PFE/FDC programmes
There is a work around for this. I am not in front of my FS computer but hopefully you will get the gist. It's a bit of messing around but actually not too difficult or time consuming.
OPen FDC.
The Cabin crew announcements can be selected on or off. So uncheck announcement 5 in the FDC programme. Whilst in FDC go to the User wav file section and select the most appropriate option in the list, you will see you can set an altitude for most Users wav files. E.G. I have " cabin Crew Seats for Landing" announce at 5000ft. You may need a bit of trial and error but it is easy to set up and works well. It does get a bit more complicated if you are using a number of user wav files. I have most slots in the table taken up.
Make a note of the User file slot you have chosen.
Close FDC.
Now you need to go into the folders of FDC. Don't forget, back up everything you are gpoing to mess with, better still the whole FDC folder structure
Go to the WAV folder in the FDC folder. Copy the cabin crew Announcement 5 and place it on your desktop.
Now go to the wav file folder and create a folder within it and call it BAK or Hold or whatever you choose. Copy the 'User ?' wav file where '?' is the number of the User Wav you noted from earlier, paste the copy into the newly created Hold/Bak folder. This means you don't have to create and 'empty' user wav file if you wish to change things in the future. In fact it might pay to copy all the user wavs into the hold/bak folder.
Now rename the cabin crew 5 announcement 'User ?' where '?' is the number of the User Wav you noted from earlier.
Start FDC, check your earlier assignment is in place and Go Fly!
I hope this is correct, as I say I am not in front of my FS computer at the moment. I know Dave and others will jump in if I have led you awry.
Good luck
Best
