I've been trying (unsuccessfully obviously, hence post) to find out why I sometimes get a flightdeck callout like this: "... (that's) Off.. O-F-F-F" with the last four letters spelt out. I've used a serach option to look for any spelling 'OFFF' within the searchable documents in the FDC folder - but nothing.
I could live with this of course (!), but would like to fix it if possible, if anyone has any ideas. (I only seem to get it when I choose an unlisted a/c, but I may possibly be wrong there).
Thanks,
Martin
