Stodge,
Are you aware that you can increase the size of the text on SD up to 150% ? Go to the SD main screen and click on the ‘Mapping’ symbol at the bottom right (it looks like layers of charts - which is effectively what it is). The Text Size variable is down near the bottom of the list. These days I always run mine on 150%.
You are right, SD are getting very iffy about Bearingless traffic since they got tied up with SkyEcho. Tim D seems to think displaying Bearingless traffic is a waste of time - which is a shame as it still accounts for about 80% of all GA traffic in the UK. I wasn’t aware that they had dropped the relative altitude from the Bearingless Target Circles as I have been running Mode-S/3D tests, which require the use of GDL90. I will check that out next time I’m flying. Unfortunately GDL90 does not support display of Bearingless targets at all (Mode-S/3D are Positional), so use of PAW Audio to back up the GDL90 Display is essential.
Best Regards
Peter
