My apology in advance as this is a long post.
I have read the User's guide and all other relevant publications cover to cover as well as viewed 30+ videos. I have a few questions I am hoping can be clarified here. I am not sure how much credibility to give the user manual. Some of the information appears contradictory.
Page 38 mentions:
"Mobile cellular data is required when using DJI Fly. Contact your wireless carrier for data charges."
Can I only fly where I have cell service or wifi? This would seem pretty restrictive to me.
Page 14/15/16 mentions:
"There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH"
I am coming from old-school Phantom Vision 2+ frame of mind. On this system, you could set your own custom battery thresholds for RTH. Yes I know the newer systems are different, but I just need some clarification:
I get "Smart RTH". No questions.
Low Battery RTH
"When the Intelligent Flight Battery level is too low and there is not enough power to return home, land the aircraft as soon as possible. Otherwise, the aircraft will fall when it runs out of power, resulting in the aircraft being damaged and other potential hazards."
This tells me I should do this manually. Wouldn't "Low Battery RTH" do this automatically?
What am I missing?
Then the next paragraph says:
"Low Battery RTH is triggered when the Intelligent Flight Battery is depleted to the point that the safe return of the aircraft may be affected".
I am confused. Do "I" initiate it, or does the IBMS/quad?
"DJI Mini 2 will intelligently determine whether the current battery level is sufficient to return home based on the current location."
Does it take into account the amount of power necessary to climb to the configured RTH altitude as well as the horizontal distance, hovering and landing when making this decision? Am I overthinking/second guessing this system?
Failsafe RTH
"If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH automatically activates after the remote controller signal is lost for more than 11 seconds. When the firmware is updated to v1.1.0.0 and above, the aircraft will fly backwards for 50 m on its original flight route and ascend to the preset RTH altitude to enter Straight Line RTH."
Does it take into account including the power necessary for the 50 meter back tracking?
What does "straight line RTH" mean? Does it mean following a direct radian from the 50 meter back track point at the RTH altitude back to the recorded Home Point?
"The aircraft enters Straight Line RTH if the remote controller signal is restored during Failsafe RTH."
If I read this correctly, the quad is already in a straight line RTH from the loss of controller for 11 seconds (see above). How can it re-enter a state it's already in?
"When the aircraft flies backwards along the original flight path and the distance from the Home Point is less than 20 m, the aircraft stops flying backward on the original flight route and enters Straight Line RTH at the current altitude."
I am totally lost on this statement.
"RTH Procedure (Straight Line)"
"1. The Home Point is recorded." Understood.
"2. RTH is triggered. Understood."
"3. If the aircraft is less than 20 m from the Home Point when RTH begins, it will hover in place and not return to home (firmware version v1.1.0.0 is required. Otherwise, the aircraft will land immediately). If the aircraft is further than 20 m from the Home Point when RTH begins, it will return home at a horizontal speed of 10.5 m/s."
No clue.
4. "After reaching the Home Point, the aircraft lands and the motors stop." Understood.
"During RTH, the speed, altitude, and orientation of the aircraft can be controlled using the remote controller if the remote controller signal is normal. However, the remote controller cannot be used to pan left or right."
What is "pan left or right"? Camera?
Thank you in advance for your patience with this noob.
