Questions about wind

[OneStooge]

I have a couple questions when it comes to wind in BS2 (perhaps in World, I don't know).

 

1) Wind direction as reported by tower. When the tower reports wind at 292*, is that the to or from direction? Doing this instant mission and the wind speed is only 2 so it's not really possible for me to judge in a hover so I need to ask here.

 

2) How is the wind modelled in DCS? Is it a simplistic steady wind or does it vary in direction and speed (shears perhaps?).

 

3) The BS has something that appears to be some sort of wind indicator on the nose but I am not sure how to "read" it. Any insight? Turning around on the ground doesn't help me making sense of it, or so it appears.

 

4) Does wind direction affect which runway the tower will assign for takeoff and landings or do we run the risk of taking off and landing in tail wind unless we merrily disregard all instructions?

1)

not sure about tower but the Wind direction given in the briefing is "the direction the wind is blowing TO", while in real live it should be "the direction the wind is blowing FROM"

so if you look inf the breifing and it says wind 90°, it means that in order to turn into the wind you have to fly heading 270.

 

2) depending on the mission setting you can have some pretty violent turbulences

Thanks heaps, Nero.ger. Direction has had me proper confused but now I only have to remember doing that bit of arithmetics. Going to be fun going back and forth between DCS and FSX and see how many times I line up for the wrong runway lol

 

So I take it the weather is more or less fixed then for a given mission? Oh well, one for the wish list perhaps, dynamic weather.

Mission briefing gives you direction TO, ATC gives direction FROM. Active runaway changes with the wind conditions, if the wind speed is higher than 5m/s (IIRC).

 

There is a dynamic weather in DCS, you can play with it in the Mission editor. :)

Mission briefing gives you direction TO, ATC gives direction FROM

 

Oh dear oh dear :) No wonder I was confused.

Looks like everybody tells something different. My suggetion: build your own mission with some strong wind and then look at the direction of the windsack at the airport and compare to what the tower says.

 

 

3) The BS has something that appears to be some sort of wind indicator on the nose but I am not sure how to "read" it. Any insight? Turning around on the ground doesn't help me making sense of it, or so it appears.

What you see at the nose is not meant for you to read the wind direction. But you can get the wind direction and speed from the PVI. In the bottom row is a button labeled something with wind.

Well, I tested it myself (don't trust any data you didn't fake yourself ;))

 

Wind directions:

 

Mission editor: set to 330

Briefing: says 330

Tower: says 150

PVI: says 150

actual wind: blew FROM 150 TO 330 (as seen by my helo being pushed and flags waving that direction)

 

So there's your info. Tower makes actually sense, as for a good start you should face the wind,i.e. get your nose towards the heading the tower told you.

 

Little additional info: Editor setting knobs have an arrow which shows the direction the wind will blow TO. Editor wind speed is in knots, tower and PVI velocities are in m/s.

"Editor wind speed is in knots, tower and PVI velocities are in m/s. "

 

If you set the editor units to metric, wind speeds will be in m/s.

Dynamic weather has the wind direction and speed at various locations shown on the editor map by wind barbs

Asset: That is massively helpful. Thanks heaps.
