It is a common misconception of non-telemetry users that one has to use a display to make use of telemetry data.
This is not the case.
Any telemetry system worth it's money has a audio alarm for every parameter monitored.
On my Jeti system, I often do not have the display connected to my module at all.
I get different warning beeps for:
- signal weakness
- low voltage at the RX
- low voltage at the flight pack
- flight pack current too high
- the programmed amount of flight pack capacity has been used up
This way, I only have to deal with telemetry when something is wrong, or I have to land due to the flight pack becoming depleted soonish.
As long as no alarm goes off, I can rest assured that everything works just fine.
Think of it like a low voltage alarm every transmitter has. I have not heard anyone complain about this feature, and it surely does not distract the pilot during flight normally.
More advanced systems, like Graupner Hott, even have voice output for every parameter, which can be activated via switch.
