VarioVoice, a flight instrument you listen to
A personal project for paragliding and hang gliding that speaks altitude, wind, thermal drift, and variometer sounds while the pilot keeps the phone in a pocket.
- For
- Paraglider and hang-glider pilots
- Worth noticing
- Reports a position after 150 metres of movement, with a 45-second heartbeat and a ten-second minimum interval.
Field notes
The project combines an audio flight interface with optional Open Glider Network reporting. Its documentation specifies a 150-metre movement threshold, a 45-second heartbeat, and a ten-second minimum interval, while distinguishing measured vertical speed and turn rate from values that would be inferred from successive positions. The page also records a limitation that matters operationally: internet-based phone reporting is not collision avoidance, and FLARM users will not see it.
