Since August 1st, it's prohibited in Switzerland to fly over a group of person with remote controled flying machine. For exemple, flying over the terrasse of a restaurant is prohibited. This restiction apply on airplane, drone or helicopter over 500gr. The minimal distance with the people is 100 meters.

So, I have developped this LUA telemetry srcipt for OpenTx which alert me when the distance of my airplane and defined GPS point is less than the defined distance.

This script add a new telemetry screen giving the name of the place, the actual distance and the minimal distance.

At the beginning of the script, there is a table where you can define one or more GPS point. For each GPS point, you have to define :
- the name of the place (displayed on the telemetry screen)
- the GPS point : latitude, longitude (same format as in google map, a simple copy/past is OK)
- the distance (in meter)
- the full path of the audio file for the alert (you can reuse the same file foreach point or specific file)

In the script, you can also define a logical switch. When this switch is ON, the vocal alert is OFF

Installation :
- adapte the script with your own retricted area and with the LS you wangt to use
- rename the script telemN.lua (N between 1 and 7)
- copy the script in the folder /SCRIPTS/model_name (becarefull space in the model name is replaced by underscore)
- place your audio file in the folder /SCRIPT/AUDIO (or where you want, it's just an idea)
