Description

Hi all,

...it is a longer story...
The essence is that we had to find a copter after a failsafe land in an area with a high density of trees and shrubs. We searched about 1km^2 on the ground an with another survey copter. We were not able to find it although we scanned through 1000 images multiple times.
Luckily, we found the copter 24 hours later the next morning due to the battery failsafe buzzer signal. The battery voltage was down to < 2.5V each cell...
What would be really helpful would be signal when in any land mode (land, RTL, crash detection). I guess some will not like it so one should be able to switch it off. Such a signal would not only help finding a UAV when it landed out of sight but also help to warn anyone who might be in the landing area.

Thanks and best regards,
Thorsten

Research direction

The issue names no files or tests; begin by locating the existing battery-failsafe buzzer and the handlers for land, RTL, and crash-detection modes. Confirm how warning sounds can be disabled, then define completion as a configurable signal for each requested landing or failsafe state without disrupting existing alerts.
