The maximum speed the drone travels in each direction in sport mode gives some clue as to how fast it can resist wind. It's pointless sending the drone 1km away, and then finding out the wind on the way back is 13m/s against you. The drone will struggle, until you can lower it to tree level. You have to watch the blue level attitude meter when the drone is still.
"You have to watch the blue level attitude meter when the drone is still."
Whilst checking the indicator when the drone is supposed to be hovering is a good idea, strictly speaking the above quotation is not correct. The attitude indicator can also give you indications as to wind strength when the drone is moving, let me explain.
The summary of what follows is that, when the drone is moving any unexpected tilt shown by the indicator indicates not only the amount of wind that the drone is encountering but also the direction of that wind.
If your are sending the drone forwards or backwards and the attitude indicator is tilted left to right or right to left that indicates there is a sidewind. The amount of tilt indicates the strength that wind and the direction of tilt indicated the direction of the wind, the tilt is such that the drone will fly into the sidewind.
This same idea applies to commanded sideways flight where the indictor also shows nose up/down tilt.
Similarly the amount by which the indicator is above of below the centre of the indicator indicates how much the drone is having to tilt to comply with the forwards or backwards flight. If the amount of tilt is less than expected the drone is flying with the wind. If the amount of tilt is greater than expected then the drone is flying into the wind.
I have seen a drone RTH with the indicator's horizon in the centre or above the centre.... meaning the drone was, by intention, RTH'ing downwind and that the wind speed was, respectively, equal to or greater than the RTH speed. |
