[size=14.6667px]For the Phantom 3, does anyone know:

[size=14.6667px]Max wind shear it can fly in?
[size=14.6667px]Max wind speed it can fly in?
[size=14.6667px]Max cross-wind it can fly in?

[size=14.6667px]Does DJI have specs for these values?

[size=14.6667px]Thanks!

I will give this a go:
Wind Shear: I have done some extensive Extrapolation's and Calculations  and have concluded ....  I have no MO FO Idea...  Dont fly in it
Max wind :  How  Much money are you willing to risk?    After about 20 mph The Fun factor Has a Limited Upside Potential.

Cross Winds :  See Wind Shear .
DJI Specs :  3x6%8#$@*&%

All the best to you and yours -donnie
****Just a little Fun-  sorry when I answered the question on " How to turn the Battery On"  I went a  little Stir Crazy..{:3_48:}

Max wind shear, how could you ever test that on a Phantom.
Max wind speed, as Donnie said, over 20mph it's not as fun. In ATTI max speed is 35mph so that would be the max wind speed BUT you'd probably lose it if you flew in that wind speed.
Max cross wind, same as above

Aloha Ken,

     When I was making a video of traffic intersections in our community at 400 feet, I had a police helicopter fly 100 feet right over my P3P.  (It looked like it was 100 feet under or right on top of my P3P but was flying at the regulated 500 feet.)   The video I took was rock-steady 100 feet under a Hughes 500.  That should be a comment on the P3 wind sheer resistance.  

Aloha and Drone On!

Aloha Ken,

     The safety part about flying at 400 feet with the police helicopter flying at 500 feet was not luck - that is regulated.  The lucky part was flying a DJI product that is rock-solid under most flying conditions.  The chopper flew right over my P3!  I never cease to be amazed.  The P3 acted like there was no disturbance.

Aloha and Drone On!

theres no such thing as a crosswind on a drone that can fly 6 different directions.  This isnt an airplane landing on one runway

wind across the direction you are flying is a crosswind, there are headwinds and tailwinds too

Yes but if the phantom can travel approximately 30 miles and hour, that is the wind limitation, it doesnt matter if it is coming at it from the side or behind or head on.  If the wind is stronger than its max speed then it can be blown away .

of course but the challenges are different depending on its influence relative to your travel dire ...

Very important topic discussed here...

In the worst case scenario upon the loss of C2 (control data comms), the Fail Safe is activated and the Phantom will seek to RTH from its pre configured altitude.

In Fail Safe mode, the return velocity is given as 10 M/s with a decending velocity of 1.5 M/s. Take into account (depending upon the point of the wind direction and if into headwind for RTH - the worst case scenario) then you need to be experiencing less than a 10 M/s headwind to get the Phantom back. Also factor in that the power drain on the airframe battery will be greater into headwind thereby reducing battery expected life on an into-wind RTH.

My Rule: Do not fly the DJI Phantom in more than 10 Knots of wind (that's 5.4 M/s). At this speed you retain a comfortable headroom of safety factors should something go wrong.

Hope this helps.

Thanks for filling in the details as I didn't know those specs. Good to know! That means one should ...

First rule of gliding (along with the other 50 or so...) do NOT get too far downwind. It can be a disaster, but if you're lucky nothing more than an embarrassing landout.
