User settable maximum descent rate for copters #460

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Another user had an idea for what should be a fairly easy to implement and 
potentially very useful enhancement.

Namely, the ability to set a maximum descent rate.

This could make recovery from high altitude or at perimeter of vision safer and 
often less catastrophic.

As a global parameter it could be enabled simply by setting the parameter to a 
non zero value (the default could be zero disabled).

It could simply apply to all modes or if desired it could be written to be 
attached to specified modes only like Simple mode.

It probably should use actual barometric altitude change to determine set 
maximum rate and adjust automatically as opposed to simple direct throttle 
mitigation.

It seems to me that the existing code should make it possible to write a single 
fairly simple function in the main Arducopter pde file that would add this 
functionality.

I would greatly appreciate your letting me know what you think of this idea in 
any case.

Good idea. RTL with Autoland on my X8 descent WAY too rapidly and ends in 
disaster. 
This parameter should apply to 'LAND' (which is not documented, but available 
via Mission Planner) as well.

Check LAND_SPEED and AUTO_VELZ_MIN in 2.9
