Description

AC3 does autolanding in certain failsafe conditions. For safety reasons and to help locate the copter after a failsafe-induced autolanding, buzzing the buzzer in intervals when in autoland mode would be good. Interval-buzzing is also likely to carry a psychological "do not touch me"-imperative in case, bywalkers find the copter after a failsafe-induced autolanding.

Buzzer could be controlled by a parameter: BUZ_WARN: 0=never (only ARM/DISARM beeps), 1=failsafe autolandings, 2=any autolanding (including manual set LAND mode), 3=any failsafe condition

Research direction
The issue proposes adding a parameter controlled buzzer during autolanding for safety. The implementation will involve modifying the Copter autoland logic in ArduPilot (likely in files under libraries/AP AutoTune or similar) to call a buzzer function based on the new parameter BUZ WARN. No existing PR or assignee is found, so the work is available. The first step would be to understand how the existing buzzer is triggered (e.g., ARM/DISARM beeps) and then integrate a periodic buzzing during autoland modes.
