There is something about it that I am failing to understand, this is resulting in behaviour I am not expecting and that is not a good thing.
My understanding is that the drone monitors the energy left in the battery and compares that with what it 'thinks' it needs to get home safely. If it thinks it is approaching the cut off point it will give a warning that it is about to intiate an RTH and, unless stopped, do so. Let's call this the safe return process (SRP).The SRP can happen before any of the battery charge warning levels are reached.
I have been learning to fly/experimenting using a couple of P3 adv's and I have occasionally seen this warning and that is not a problem but I also have the impression that I have occasionally NOT seen this warning and have then flown 'into' the low battery warning level and continued flying expecting the drone to initiate the SRP. When it has failed to do so I have been left with the drone hitting the critical battery level threshold and telling me it is going to descend. Fortunately I bring the drone fairly close to 'home' at the low battery warning but two of these occasions have produced 'hairy' landings.
Tonight I deliberately set out to try and get an SRP and didn't.
I believe that if the drone is within 20m of the home point it will NOT attempt to RTH but simply land so I had the drone hovering at a height of about 5ft a little over 200ft away from the home point. The drone and I were in an empty grass field and it hovered quite happily into and though the low battery zone that I think I had set to 25%, when it crossed the critical battery level threshold, which I has set at 19%, it tried to land. I saw no SRP notification and I would not hear one if there is one as I am deaf. Now I admit I could have missed the warning on the screen but I don't think I did.
I am not certain if this behaviour is shown by just one of the drones I have been using or both.
So, my question is ...... do I misunderstand the SRP? IF so can someone please correct me?
What happens if the SRP is somewhere between the low battery warning level and the critical battery warning level?
Thanks
