Sorry I wasn't clearly explaining what I meant. I think the Mavic Pro has a setting where the craft will move horizontally (or vertically) if it senses an obstacle ahead of it. Many people turn this feature off so the craft doesn't move sideways (or vertically) into an obstacle since there are no sensors on the sides or top. Isn't that the same as the APAC being talked about on the Air? The Air doesn't have sensors on the side or top either. The difference I think is in how smooth this sideways move is. In APAC it seems to be very gentle but in the Pro I think it may come to a stop, move 90 degrees right or left and then start forward again. I haven't tested this so I don't know for certain, but I do remember the option under sensors.
