Example of the ELT automatic message, after an unfortunate accident

The ELT (acronym of Emergency Locator transmitter) is a device which send a message in case of aircraft crash. That message contains info about aircraft model, owner and approximate coordinates of the crashed plane, and it is made to request SAR (Search and Rescue) services.

Test

For testing the device proper function, just press the ELT button with your central mouse button (in most mouse models, the wheel). The red light will turn ON. Loose the button to stop the test.

Activate

Press the ELT button with your left mouse button, and the light will turn ON, and the device will be armed. In case of an accident, the device will send a chat message containing relevant information:

  • Aircraft model
  • Callsign
  • GPS Coordinates
  • SAR service request

Example: ELT AutoMessage: Cessna 337G Super Skymaster CC-FLT testing ELT at -32*56 41.3S LAT -71*28 16.3W LON, requesting SAR service

For developers: Install an ELT in your aircraft

Actually, the Cessna 337G Skymaster is the first and only plane equiped with a functional ELT on FlightGear. You can get the instrument from it. An independant download link will be provided soon.

To install it, you just need first to copy the folder called ELT in your instruments directory, and put the remote (ArtexELT.xml) like any instrument in your panel. The second step is to link the nasal code in your aircraft-set file, just typing some like this:

<nasal>
 <ELT>
  <file>Aircraft/Cessna337/Models/Instruments/ELT/ELTmessage.nas</file>
 </ELT>
</nasal>

Be careful checking the right nasal file route. The code will get the aircraft model name and callsign for its own, so you don't need to modify it.
