This is a modified version of the HEMS Generator by D-ECHO. This version adds voice effects to the radio communications and some background changes.
With this addon, you can use any helicopter to simulate HEMS and SAR type missions which can be randomly generated.
To instal, simply download the package and tell your FlightGear where this addon is instlled on the launcher.
If it is installed correctly, you will see a new menu item in FlightGear's main menu ( F10 menu ) in sim, called HemsGen. From this menu you can set various options and you also have help for using the radio dialogue ( you need to keep the radio open once the mission starts ). Select " New Mission site" to start your mission.
To hear the radio voices, you do need to alter the helicopters sound.xml file where it loads all the sound files. Find the file and open it with a text editor. At the top of file you will see a line like this:-
<PropertyList>
Change it to this:-
<PropertyList include="[addon=org.flightgear.addons.HEMSGen]Sounds/sound.xml/">
This reads the additional sounds from the addon. FlightGear can not reliably play sounds from the addon on it own. This is why this change is unavoidable. If you do not change the line, the addon will still function, but without the sounds.
**** NOTE - If you remove the HemsGen addon, you must change your sound.xml file back to read just <PropertyList> . Failure to do so will result in your aircraft having no sound at all. ****
