temps suggesting 55F ( 13C ), so no ice should form, no wind warnings in logs, and he mentions wasn't windy at all, winds from log vs weather data suggesting 11 MPH ( 5 m/sec) so wasnt flying in excessive winds even if he was i have flown in strong winds and even in strong winds shouldnt freak out too much to trigger failure. and his max recorded speed is 79.59 MPH which means something catastrophic occurred sending it diving into water. the telemetry suggests and atti mode, but the user mode data was suggesting position mode.
lot wrong with this one, DJI needs to jump on this, i beleive he owed a replacement unit and i think dji should consider more firmware updates and optimizations.. this has happened sparatically with mavic air, but i feel enough times dji should look into adding another softwsre level safty function to help prevent this, somehow.. given amount of info and telemetry these drones gather, i imagine dji could identify signitures in telemtry indicating something is wrong and failsafe out of it..
I think speed you read at 79.8mph is not a true speed, easiest way to measure this is to speed per ft per second and at 80mph he would be covering approx 120ft per second ,at 80mph his drone was only covering 70ft, which is about correct for top speed in Atti or Sport mode for Mavic Air 45mph, so although log was showing 80mph, this was not the speed the craft was travelling at, it’s just an incorrect reading.
So I don’t think there was anything strange in what happened with Aircraft going to Atti mode, the strange thing was how craft lost height so rapidly, I wonder if there was a problem with barometric pressure which caused other problems with craft.
I worry because it’s normal if no proof of malfunction can be proved in the mobile logs, dji have usually gone with no fault and offered 30% discount, we shall wait and see. |
