Arducopter SITL Stops Moving in the Middle of a Flight Plan

ArduCopter Copter 4.5

Hello,

I am running Arducopter SITL V4.5.7 and having some issues when executing a flight plan. For some reason, the copter stops during my mission and I cant control it anymore. It seems like it just freezes and locks me out of controlling it.

My first thought was to increase the fence radius, but that didnt help anything. I am hoping someone can help me out here.

My parameter file is here:
copter_sitl.param (24.1 KB)

Flight plan:
hospital_to_verona.txt (1.3 KB)

Point at which it freezes:

Thanks in advance!

Fixed it thanks to some people on Discord.

The craft was running into the ground (a mountain). You can test this if it looks like it freezes by disarming it and seeing if the altitude drops.

Quick fix is to just disable SIM_TERRAIN parameter in the configuration so that Arducopter thinks the earth is a perfect sphere.

You can also overlay a terrain map by typing CTRL+W in Mission Planner and selecting terrain.
