Does anyone know of a way of setting a minimum altitude for the 2 pro. I think this would be a useful safety feature for example setting a minimum altitude to avoid tree tops, flying in parks where someone might walk into the field, or in waypoints etc. Yesterday, I accidentally set 1 waypoint at 2 metres over water (it should have been 50. ( Long story but I think I found a bug in the waypoint setting function.)

Being able to set a "standard" minimum altitude could have flagged up an error asking me to check the altitude for that waypoint, and not allow me to fly until confirmed. Almost lost a brand new out-of-the-box 2 pro (warranty replacement). The drone was 200 mtrs out over a bay and I wasn't sure whether its apparent descent was parallax error or actual descent. Sun was obscuring the screen. Hit the brake button "just to be safe" and discovered the drone was about 3.5 meters above the water and heading down to 2 meters. It might have stopped at 2 mtrs then head to the next waypoint (50 mtrs alt) but it was too close for comfort. Scared the living daylights out of me as the descent was totally unexpected. It should have been all 50 Mtrs altitude. If I had taken my eye off the drone or lost sight for 2-3 seconds, it would possibly have been lost.

For some time I have thought that a simple minimum setting could avoid at least some accidents or losses.

sadly there is no way to set a minimum,  it probably wouldn't be much use as it would be relevant only to the take off point.

Update. I re-created the steps I took to create my (almost) disastrous mission and discovered something others may be interested to know. DJI go wont allow waypoint missions to be created unless the drone is turned on. After creating 4 waypoints (all at 50 metres), the drone turned off (flat battery) without my noticing, just at the moment I was going back through each waypoint to check the settings. The waypoint I was checking (no 2), suddenly dropped in altitude setting from 50 mtrs to 20 and no amount of "swishing" up and down on the screen could get it higher, only lower. All others remained at 50 Mtrs until I clicked on them when, without any input from me, they also reset to 20 Metres.  I replaced the battery and after a couple of minutes, was able to reset to 50 metres, but missed setting the waypoint 2 back to 50 metres, instead leaving it on the unintended confused/ erratic lowest point of 2 metres. Had I ended my "swishing" upwards, it would have been safe at 20 mtrs.

I have managed to safely recreate the ïncident" several times. Uninitiated resetting to 20 metres happened each time.

So if your drone loses power during waypoint setting in DJIgo app, recheck all your altitude settings before flying.

It was a very close call. Checking data logs showed my drone bottomed out at 1.9 mtrs above the bay.



My drone is ok but could this be considered unexpected software behaviour causing pilot confusion, after all, I had set all the parameters correctly and was merely confirming things before flying.

If you are doing a lot of waypoint missions you might want to look at litchi,  you can plan and test fly them online before turning on the drone,  you can also see other people waypoint missions and their results on their hub.   You also get a bit more control at what the drone will do as it flys,  like looking at POI's,   smooth corners,   photos etc.
