HOW TO: Measure the wind speed during flight
- Thread starter msinger
- Start date
On a P3, just switch on atti mode, and see what speed she does in a hover.
Does the horizontal speed register when drifting with the wind and no stick inputs?
Sounds like a newbie question... but I never paid attention to it when in ATTI (not often) and in hover.
Usually when I do that I'm looking at the Drone to make sure it doesn't drift into anything....

Deleted my previous post cuz I don't know. LOL. Without gps, how? I don't use atti on purpose. Try it.

In atti mode the speed over the ground will be displayed, just as it is in P-GPS.
It's easy to test.

Too many flyers only realise they are in a strong wind situation when trying to come home after flying off downwind.
If you are concerned about possible strong wind, the simple solution is to try flying into the wind before flying anywhere downwind.
If you know your drone flies at 15 m/s in still air but can only manage 5 m/s pushing against the wind, you've learned all you need to know to decide which direction to fly and/or how far away to fly.

Yes.
It is...<;^)
I hear ya. But, yes, the telemetry data will report back wind speed. It works kind of like this:

Nice feature in DJI Go 4 but it would be great to include it in DJI Fly

Or .. you can easily try to fly directly into the wind and observe how much that reduces your top speed.
The think about how that would affect your return flight before you fly long distance downwind.
Thx. It’s easy to get complacent flying GPS mode, I forget I need to practice ATTI in case of emergencies. That will be corrected...

ATTI means not that the drone is without GPS data it only doesn't use it for flying. But it can still measure the speed.
So not pushing the sticks it can pretty exactly measure the speed of drifting and after ten or 20 sec this is the speed of the wind.
If I'm not sure to fly or not I just put to hoover the drone above my head and see how it holds the position if not then you'll not fly. For additional confirmation you fly into the wind and see the drone speed. If it can manage only half of its normal speed put it down. The wind will be stronger as the drone going higher.

It also helps to do a tiny bit of research before going out. As easy as going to www.windy.com or your local weather & plugging in the zip code of your intended light zone.
Not 100% exact but, certainly in the ballpark whether its going to be 5-10mph or 18-25..... or more.

If there is some wind I always check the UAV forecast which I have at the home page of my phone.
You can set the parameters at which flying is not recomended. It is not really online but useful enough to decide fly or not.
Beside that it shows you also the wind speed for every 100 m up to 1500 m.
