We faced an issue in autonomous mode survey grid yesterday. We had 5 flights with different auto missions with 2 separate batteries with changing the velocities from 5m/s,6m/s.7m/s. We had a stable flight for first 4 flights
In the final flight drone we changed the battery (Note:there is sudden change in wind speed and drop in temperature around 3-4 degree temperature before 5th flight, which is common weather change in India during summer evenings) drone with velocity 7m/s in auto mode, the drone losses its control and wobbled like hell, expected to have a crash landing.It didn’t come to control even when we changed to manual gps mode, We took around 5 minutes to take control on drone ( to be honest we thought drone would be crashed) and analysed the logs but couldn’t find the exact reason behind it.
