Plane:reset in landing seq on mode change while disarmed

[Hwurzburg]

if you lose rc or accidentally change mode to rtl while disarmed on the ground with a DO_LAND_START setup you will prevented from arming when rc is restored or mode changed,if you dont have a gcs to reset the mission ...unless you power cycle

this will reset the mission to allow arming on non-autothrottle mode entry IF.....in landing sequence, disarmed, and not flying

tested in SITL

I had a a similar problem after landing successfully earlier this year. Without a GCS I would be stuck and unable to arm. It would even survive a power off reboot. This might fix that too.

This seems like quite a cryptic combination of things that will cause a mission reset. I wonder if people will hit this by mistake and be confused. We do have a mission reset aux switch.

[Hwurzburg]

This was Tridges suggestion to avoid exactly that.... And most that have this problem don't know what to do about it

[IamPete1]

Starting landing sequence in RTL is expected behavior. Yes its annoying in the case you describe, but the vehicle is behaving as expected and as it would in flight. This new reset is unexpected, it can happen when you switch between completely unrelated modes.

I see the argument that the vehicle is "stuck" in a state where you can't arm, but I think is a bit odd to magically fix it on mode change. Why not do the reset the first time the user tries to arm and hits the arming check?

that got me thinking...no need to rest the mission really...we dont do that on partial missions anyway #25263 as alternate

[tridge]

please add in a GCS send text for "In land sequence: mission restarted"

thanks!
