No, that is exactly what "Smart Return Home" feature does. Depending on how far away you are from your launch "home point" the Phantom 4 with it enabled calculates how far away you are from your home point and how much battery it has left in order to return. If you fly far enough, fast enough, the Phantom 4 may execute a "RTH" command based upon this feature at greater than 50% battery life. When it occurs is dependent on just how far away you go from the launch point not battery level as you are describing. My settings are such that the Phantom 4 will auto land at 10% and will give me a low battery warning at 30%, however, the Phantom 4 will not try to RTH or auto land. Anyway, you want to disable this feature if your flying on the open ocean, disable RTH on loss of connection (set it to hover) and always be ready to bring it in when you reach the 30% battery level.
As for canceling it when the error appeared on screen, there was no way to do so. Once initiated the "Smart Return Home" feature was locked in. At least it was a month or so after Phantom was introduced.

Maybe it didn't work properly at first, but on the last but 1 flight I made, it did decide to RTH due to low battery (if you consider 48% to be low!) it did give me 10 seconds to cancel the RTH which I didn't do, then when it was 150m from home, still with 39% battery left I cancelled the RTH using the RTH button on the remote control and continued flying for another 5 minutes landing at 19%.
Since it does give you the opportunity to cancel the RTH both before it starts and at any point on the way home, I don't see a need for an option to disable the RTH, probably better to leave it on and then cancel it when it activates since if you sometimes fly from a fixed point it is a very useful reminder even if you don't use it to do the flying.
It would still be interesting to know if that option in the object avoidance settings does what it says it does, or is actually the option you used to use to disable RTH?... I'm not sure why anyone would turn that off? Does it fly faster if you turn it off? |
