Hi Guys,
Thanks for your input so far.
- @BudWalker and djiuser_xLE6O03, I will post my .dat file but unfortunately this will have to wait until Tommorow.
- @Charles Adams, thanks for your insight. I must admit, I too suspected that it may have been the light pole near from where I took off; I guess what I am curious on is why on the return flight home (similar path to where I took off), there was no interference? As a side note, the lights were off.
Ultimately however, what I am more interested in is the best practice that can be applied in situations like these. I accept there is always going to be a degree of risk that technology or enviromental factos that may result in such incidents, but what I think the important thing to take away is the best practices that can be applied when they do.
In my case, I noticed that it went into ATTI mode, I did the following things (this includes my questions and commentary), hopefully we can take something away....
- I immediately climbed in altitude (within my local guidelines), to reduce the likelihood of my AC drifting into any low objects and crashing down onto anything. Is this recommended?
- I was also wary not to press the RTH button (although) not sure this would have worked because the GPS was disabled, however if I did, could this have made the situation worse?
- I also have a question surrounding handling of the AC when in ATTI mode, my understanding is that the only the X (Forward/Back) and Y (Left/Right) axis are not controlled. In my case I also had a Yaw Error. At the distance the drone was, it's quite hard to fly LOS and to see the front of the AC. To contend with the natural movements of the AC, do you think it would be better approach to fly back, zig-zagging home using the FPV display (while resisting the AC's natural movement).
- If I didn't do anything but let the AC drift in ATTI mode (assuming it cleared all objects), would the AC not stabilise itself as it is naturally drifting and potentially flowing away from the source of interference; in this case would it not just switch into GPS mode? Obviously the risk here is that it drifts too far and although it returns to GPS mode, perhaps the transmission is lost, on that note; would it not try and RTH?
- What is the best practise/what thresholds do you guys use to observe compass interference prior to take off?
- Is there anything else that one can do to pro-actively recover the AC once it is in ATTI mode?
