The system provides Ethernet access to engine and flight data, automatically.  Alakai's optional Wireless unit (also STC'd) is available for automatic 'hands-free' internet access to your aircraft, and enables uploads to GA-FDM analysis tools and services.

On the ground, ETMS contains a built-in web and mail server, so your aircraft can email you summaries, and upload analysis data to the GA-FDM site.  Or, use a laptop or PC to browse through recent flights and examine engine data using the built-in web-server. Data can be:

  • emailed right to your PDA or iPhone
  • Graphed and viewed using any standard web browser
  • Downloaded in text format for incorporation into your own documents, spreadsheets or logs
  • Retrieved using a USB Flash memory device (aka thumb drive)
  • Graphs can be printed, for inclusion in maintenance or pilot logs
  • Also generates flight visualization track files for playback of every flight using GoogleEarth Pro
