?? Wind direction in CDU ??

[JEFX]

Hi! all.

 

I wonder if that is right, but I have been experimenting with the wind strenght and direction.

 

If I set up a wind in the Mission Editor like this :

 

SEA LEVEL : 5 m/s and GOING north (meaning the little arrow pointing up on the dial)

which would roughly mean a 10 knots wind from the south at sea level...

and then

2000m : 10 m/s GOING south (little arrow pointing down on dial)

which would roughly mean that at 6000 ft, I get a 20 knots wind from the north.

 

when I fly the mission, I dial up the the WP page on the CDU and then the WAYPOINT sub-page, which gives me the wind speed and direction on line R8 as stated in the manual p. 235 'current wind direction in degrees'.

 

My question is : it seems to be giving me the direction TO WHICH IT IS BLOWING (and it works very nicely, flying down from 6000 ft to sea level, the wind switched 180 degrees and the proper speeds were diplayed)

 

Is that correct? or would it be better that it gave is the direction FROM which it is blowing? (I believe like in METAR)???

 

 

thanks

If memory serves me right, wind is usually reported as the direction it is blowing from. This is in the meteorology standard weather report format.

 

Now the CDU may be set up with a format for the ballistic calculation computer to handle, mind you, this is pure speculation on my part.

 

I thought I remembered reading on the Forums that the wind reporting in the CDU is fubar, and was being addressed.
