[QUOTE="nilanjan118, post: 88681, member: 13902"] OK. That doesn't explain the abrupt change in AC attitude but if you see the screenshot I had shared above, before 3:14.5, the VPS sensors are detecting something below, hence the speed is less. Beyond 3:14.5, they detect nothing and your AC's speed start increasing. The manual states that max. descent speed is 3m/s (~11km/hr) while auto landing, which your Spark was doing. The only way to get cushioning or reduced speed while the Spark is auto-landing is by having fully functional bottom sensors, which obviously wasn't true in your case. So what you saw as fast rate of descent was the AC's normal rate of descent when the bottom sensors don't detect any obstacle below. Regarding your question about internal damage, even DJI would ask you to send the drone to them if they have to ascertain if there are any. I think you should get the bottom sensor checked if you do not want similar incidents in the future. [ATTACH type="full"]9754[/ATTACH] [/QUOTE]
