A PDA file is valid for OLC. OLC approved quite a few PDA
applications (including XCSoar and most/all commercial ones).

And it is trivial to fool any PDA software by sending fake NMEA data
into its serial port (Condor or fully synthesized). That NMEA stream
may include fake pressure data and even fake ENL data.
