Default Wind correcting Dumb Bomb Delivery

Hi All,

I have had a mixed bag of results with the use of dumb bombs in CCIP and CCRP, generally speaking, flying skills apart, the issue is related to wind (not diet related, but atmospheric).

I have just gone through the procedure of entering wind correction into the CDU to correct for this, and the results speak for themselves.

Below is the walkthrough of the procedure I use, I hope it is of some use to you fellow sim pilots, and hope I am not teaching you to suck eggs!


Sorry for all the pics!!!


CCRP bombing, paired release @ 6000 ft 210kts. Wind 270 degrees 15m/s






As shown above, the bombs missed their mark, and no damage done to the target. This was a stable release, wind accounting for the miss.

Procedure for correction:

1) On the CDU panel, press the SYS button, then press the LASTE button:




2) Click the wind OSB to enter the wind correction page:



3) This is where you can enter the wind correction data. Start off by entering the altitude of the first layer of wind. I start with ground level. To do this, enter 00 in the scratch pad, then click the first empty line on the left to enter this altitude.



4) Repeat the process for other wind layers if known. What I did here was repeat the wind speed and direction data for my altitude, so the adjustment calculation took place. In this case I entered 06 (for 6000ft) and placed that altitude in the line beneath the first:







6) When you have enetered all the layers you desire, press the WndEdit button.

In this step you enter the wind speed and direction.

How you get this data is up to you You can get it form the mission editor, Air traffic, even the JTAC gives the wind vector for you.

To enter the data you have to enter 5 digits. The first 3 digits is the direction of the wind, so 000 = north and so on.

In this case, 270 was the wind direction.

The 4th and 5th digits is the wind speed in m/s

So wind speed 15 ms at 270 degrees, we enter 27015.

If wind was at 10 degrees and 7 m/s, you should end 01007

Once entered, hit the OSB for the layer you want to add this data. Repeat this for all layers.




7) Next step is to add the temperature data for each layer. Again get this from the ME/brief. You also have the current temperature shown in the CDU on the top right. I just used this temperature accross all layers. 18 degrees here.



Once done, hit the WIndTemp OSB to go back a step and store the data:



9) Get yourself lined up.... and bombs away!!!!





"Good bombs, good bombs"





BDA flyby:





As you can see from the result it seems to do the job nicely!!! The smoke also blows along the correction line...


I would like to say there is no camera trickery here, and I hope the above isn't just a placebo, and my first run was just bad. But I tried this out a few times, and it appears to do the job. Let me know how you get on!!!


Also, thanks ED for making this sim so involved, things like this are great!


Happy bombing all!

Outstanding! I had just posted my frustration on this same topic. Thank you for taking the time to share.

So am I to guess that the altitude dosent matter for wind? If its 270 for 5 thats what it is for all altitudes? And can you enter up to three altitudes? Awesome post also!

Weaponz: have another read through You can add several wind layers.

Thats what I figured but I dont remember the game itself breaking down wind for differnet altitudes? I thought it was one set wind.
