Hi Roy,

This is a valid complaint.  To a certain extent, I'm currently
concentrating on getting the actual logic of what's transmitted improved,
and on editing some voice files to replace the text display.  However, the
text display will always be needed as a backup for those without sound, so
eventually this should be addressed.

I can think of a number of improvements.  The first, and one which would
also help the voice output, is that many of the airport names pulled
automatically from the DAFIF are far too long - for instance "Metropolitan
Oakland International Tower" should almost certainly be simply "Oakland
Tower".  I'll go through these and try to manually change as many as
possible to what seems right - in fact I'll run a script to remove
"International" from all of them.  Some of them are tricky though - should
"Brisbane Archerfield" be "Brisbane Tower" or "Archerfield Tower".  I'm
guessing the latter since there's also a Brisbane International.  What
about "Burbank Glendale Pasadena" - that could be any of the three!  If
real life pilots, or those who otherwise know definately, could send me
corrections for their favourite airports that would be great.  There would
be a double benefit here - less length of message to read, and less of it
going off the edge of the screen.

As for the actual time the message is displayed for, currently messages get
overlaid if they overlap, which means that the message resisdence time has
to be kept fairly short in order to keep the dialogue within a reasonable
time.  However, as you say, it could be possible to dynamically stack the
messages to allow a longer resisdence time.  Additionally, this could be
made user preferable, and also related to message length for each message.
It could also be possible to display each one in a pui dialog box and wait
for OK to be clicked before removing, but that would require the focus for
the return key on the ok button to be kept on the earliest dialog box,
which could be tricky - I imagine the most recent message would tend to
grab the focus each time.  The current messages can be hard to read at
night - some different colours, and possibly a background colour, could
possibly be an improvement.

All the text display stuff is in ATCdisplay.cxx and shouldn't be too
complex - feel free to hack and send patches!  I'll try and take a look at
it sometime and get something more reasonable in.

Cheers - Dave
