Who are those questions for?
RTH and related functions are something I try to make a point of experiencing in experiments before I encounter them in real flights, my P3adv taught me that.
However the
M2P and MM have still managed to catch me out when I start combining behaviours, the
MA2 ( I do not have one) looks even more complicated.
Qu) Do you know what happens when you activate the "landing" button on your controller? Does it land right there or RTH?
Ans ) I almost never use it as I normally land using manual control or hand catch and I have
never used it when the drone was anywhere else but within maybe 6ft of me. One reason being it can not be relied upon as the drone can reject the landing site and for that matter so can RTH.
Qu) If your RTH altitude is higher than the present altitude, does it ascend then fly to you, ascend as its flying, or return then ascend?
Ans) depends on the drone, the distance from the home point and if applicable other flight control options, in which case it is too complicated to go into here and I am sure there are some permutations with the
M2P that I have yet to discover. The
MA2 looks even worse.
Qu) What battery level triggers RTH?
Ans ) Varies with distance and height and presumable RTH height if a climb is required.
Qu) Can you override it?
Ans) Yes, all to easily.
Qu) How long can you keep it in the air if you absolutely have to with the drone fighting you to try to land?
Ans) If push really comes to shove, until the drone's control software kills the motors to 'save' the battery.
I think the Mavic xyz CSC behaviour is another thing that needs careful 'study', there have been several posts where it 'failed' to bring down a drone because the behaviour is incorrectly understood.
I was fortunate in that the wording of the manual, concerning CSC, worried me and I investigated it.
If I had not I would still be flying with the impression that the CSC will drop a Mavic xyz from the sky under any circumstances.
I have brought my MM down from 100m+ in a lovely helix using the CSC position when the response to the CSC was set to "emergency only". It was powered and under control the whole way down and even automatically slowed its descent as it approached the ground. It hovered when I released the sticks.
I have also tried the "anytime" mode, from 2m, and the MM descended under power for a little bit then fell the remaining 2ft or so onto grass, I tend to mix my measurement units.
