I tried a flight when it was about 21km/h on the ground. Using other apps I find that is do-able, but this DD flight had to go against the wind to get to the start point. It was moving so slowly that I had to abort
0.32 km/h is way too slow to get to the first waypoint.
Airdata have just updated their service so that now we can get in flight wind speeds even from past flights
So in conclusion, wind speeds of 32 to 35 km/h is too fast to fly a DroneDeploy mission
