I just found a DAT file in the folder on my phone where the logs are stored. It corresponds to the time of the flight where I had the problem. I put it up on google drive here: DAT FILE from flight Maybe this is the dat file with the fuller data you are looking for?
It looks like you uploaded the TXT file rather than the DAT but that's fine, because it has enough information to figure out what happened.
The Cape Cod Coast Guard Air Station recorded winds winds out of the southwest at around 10 MPH at that time. However, that was a bit to your west and farther inland, and 10 MPH would have been the wind near ground level. Being so close to the water and at around 340 feet it's not surprising that the wind might have been too strong for your Mavic and would push it towards the ocean; winds at higher altitudes are often very different (usually stronger) than what you experience on the ground.
If at all possible you should plan your flight so that you have a tail wind on the return trip, but if you find yourself in that situation anyway the best thing to do is fly it back manually (without RTH) using Sport mode. Also keep in mind that winds are often stronger at higher altitudes, so if it's safe to do so you may be able to get it back without sport mode simply by reducing the drone's altitude. Anyway, I'm glad your Mavic survived the flight and hopefully now that you know why it happened it's something you won't have to experience again. |
