Upon initiating a RTH for whatever reason (smart, low battery, signal loss), does the new Phantom 4 Pro automatically enable all/some of the Obstacle Avoidance systems?  
Let's say you fly out & then go into sport mode for a bit - now you lose signal...  What happens with the whole OA & the smartness of the drone?

Hi, it will work if the light condition is ideal for the Obstacle Sensing System even.

So, if OA was OFF prior to the RTH (like being in sport mode), the Phantom 4 Pro will re-enable the sensors?

I appreciate the clarification.

that makes me feel much better about the OA
