This is interesting!
So sure there are 1 pc compass built in, but it is not too reliable. The common mistake is that it is not the main problem that it enters into ATTI mode, but because of some software (firmware) error, the connection and control are interrupted, which in this situation (ATTI) may lead to the loss of the drone.
The DJI does not comment on how the Spark firmware handles the compass bug and what causes these errors.
I've also watched flights on Youtube and read many threads on this problem. It seems to be a fairly broad range of symptoms following the error, but almost all of them are due to the compass yaw error. Most of them appear to be slowly traveling in one direction, not in sport mode when the error occurs. Most of them seem to be far out into the country, no houses, buildings, etc. There is always at least a jerk/twitch when it happens, but sometimes it yaws wildly, and rolls to one side or another. It appears that the pilot tries to correct, but has a hard time keeping it leveled. I can't tell for sure what the pilot is doing because there were no stick overlays on the videos, but from the threads I've read, they say it was really hard to control and some instances laggy connection and/or extreme control lag.
As far as flyaways go, I'm still trying to figure out the root cause. I know a lot of instances are proven to be pilot error, not having the skills to manually fly in ATTI mode and bring it back to their location, but some of them appear to have a mind of their own. They claim that they just head off into the sunset, never to be seen again, but I wonder how many of them are simply drift due to high winds while stuck in ATTI, or maybe accidentally controlling the spark in the wrong direction and out of RC contact. |
