Not quite. Although most of the time the HP is the same as TO, the HP can be changed during flight.Hi there & welcome to the forum [emoji112]
The RTH height is always in relation to the recorded home point ... so if you set the RTH height to 30m for instance & fly down 1500m into the valley the height reading will show negative 1500m & when down there command RTH the drone will ascend up 1530m (30m above your HP).
But be aware that this will most probably break the regulations due to that the RTH sequence is 1. Turn to HP 2. Ascend to RTH height (and here you will be 1530m above ground at a minimum) 3. start to travel back.
Assuming you're far enough away from HP, RTH will first go to RTH set altitude relative to TO. Then the AC will turn towards HP, then start flying to HP.Thank you for the information. If I understand this correctly, the RTH will work.
According to the rules, one should stay within sight of the drone, which should be about 120m.
The drone in my RTH example, however, flies first back the negative meters to the home point and from the home point another 30m above.
(so I hope so). Question; it's this the same calculation as if I'm flying up from the HomePoint 1500m to the top. Thank you for your help and nice greetings to Sweden
As far as I could sort it out, the max altitude for Mavic 2 Pro is 5000m above the sea level, however it is 500m from the Home point recorded. DJI GO 4 doesn't allow you to set up max altitude above 500m.I will be filming in the Swiss Alps. I will fly down from Home Point 1500 meters into the valley maybe ca. 200 meters or less over ground. How high do I have to set the RTH in meters so that the Air 2 comes back safely. Thank you for your answer
