Planned a Litchi flight for my Mavic Air along a river: good line of sight available all the way, with a short cut back to the starting point over two car parks.
Waypoint height: 90-110m AGL, cruising speed 25 km/hr, 9 mins estimated, 5’30" actual
Flew at ~3pm, and the mission went exactly to plan. The weather was dull, and the pictures weren’t spectacular:
The sun popped out for a minute, so I used my second battery for another go at the same mission. However, the sun disappeared quickly, so disappointing results again:
Spotted the sun from my hotel room, and still had one battery left, so ran the same mission again.
This time things went badly wrong between Waypoints 14 and 15 - see 4K YouTube video:
(I will leave this video up for a few days)
This was the scariest point:
When I was supposed to be 90m in the air over a car park, I was 2-5m above the flat roof of a two-storey building.
I have looked at the flight record:
I may accidentally broken the Mavic Air speed record:
Other than that, the data tells me very little. The batteries seem fine, there are 13 satellites, and even when the flight was 70m lower than intended, it’s got 68% radio signal…
I have no idea how the death spiral was averted. To the best of my knowledge, I didn’t touch the sticks. I think a message came up on my screen, and I remember thinking from the view on the screen that I was far too low, but soon the familiar Mavic Air noise was heard above me.
Any idea what caused this?
Is it going to happen again?
