EX5000 Release 8.2.2 Installation Manual
- 18 -
Some installations of EX5000 MFDs have been made with Garmin or Avidyne 400 and
500 series GPS units connected via RS-232 under previous revisions of this installation
manual. Those installations are known, non-compliant installations with respect to
TSO-C165 as curved paths from the GPS are depicted as straight lines on the MFD.
Avidyne recommends customers with Garmin or Avidyne 400 and 500 series GPS units
connected via RS-232 switch to an ARINC 429 connection, otherwise the following
warning must be added to the pilot’s guide: “Warning: The EX5000 MFD will display
straight lines instead of curved lines when curved paths are in the flight plan of a
Garmin or Avidyne 400 or 500 series GPS unit.”
Installations of EX5000 MFDs with Garmin or Avidyne 400 and 500 series GPS units
under this installation manual must be done using ARINC 429.
