loo_ohs Posted February 10, 2015 Share Posted February 10, 2015 (edited) As you can see, we have a 20°, 4m/s wind at 10m, a 310°, 6m/s wind at 2000m and a 270°, 8m/s wind at 8000m. However, this is not all. As the game engine calculates for a natural drop in wind speed at very low altitude, it needs to upscale the wind speed above. We have already entered the wind speed for 10 meters, but the wind speed for most of the bottom layer of wind will be TWICE (2x) that entered in the ME. So in fact, we will have a maximum wind speed of 8m/s from about 350 to 650m. So layer by layer we actually have: 10m 020° 4m/s 500m 020° 8m/s 2000m 310° 6m/s 8000m 270° 8m/s We now have our layers. The mission editor displays in which direction the wind is blowing to. The CDU shows the direction from which the wind is coming, and it shows the magnetic, not the true bearing. So to convert these bearings we need to add 180 to any values below 180, and subtract 180 from any values above 180, to get the bearing on the opposite side of the compass rose. Then we need to subtract 7° to get the magnetic bearing. Eg. 020° + 180° = 200° 200° - 7° = 193° We also need to convert all wind speeds from m/s to knots. This is easy, just multiply each value by 2. So what we end up with for the CDU is: 10m 193° 08 knots 500m 193° 16 knots 2000m 123° 12 knots 8000m 083° 16 knots Now we need to enter this data into the CDU during flight. My English is very poor.Please try to understand what I mean. First of all,thank you to make the practical numerical conversion software. On this topic, I want to know is: 1.Why is 2 times of coefficient,instead of 1.87 times, 2.3 times......... 2.How to get "about 350 to 650m" ?

Under 6000' CCRP steer points are all over the place until release Wind correction doesn't seem to help with CCRP even with 5mil consent. Bombs are sill 50-100' off The same settings with CCIP allow mk82 drops right on target. This has been the issue for a long time, and I've tried all sorts of methods to measure wind speed at altitudes including noting the wind on the CDU itself as I climb.

This has been the issue for a long time, and I've tried all sorts of methods to measure wind speed at altitudes including noting the wind on the CDU itself as I climb. Tbh, the last time I worked myself through the threads I was refering to was at least 6 months ago. And as those threads also meander back and forth about a lot of details, I can't really say if this specific issue was covered or investigated back then. I only remember that the overall conclusion was, that CDU wind correction does work (i.e. it was broken but was then finally fixed), but is simply no silver bullet to all difficulties when it comes to precisely hitting stuff with dumb bombs. So, could you perhaps post a link or something to the bug report here on the bug forums? Edited February 10, 2015 by Flagrum Link to comment Share on other sites More sharing options...
Kimi_uy Posted February 10, 2015 Share Posted February 10, 2015 If I don't have any wind info on the mission, I usually read the wind values off the CDU as I climb out. If you're entering these as you go, make sure the wind correction is set to NONE, to make sure you're getting the aircraft's readings, not the one's you've manually corrected for. And then of course, once you have all your layers punched in, remember to set it back to WIND or BOTH, to make sure your changes are taken into account. ^^THIS has made my life easier. I've tried it with multiple wind settings and works each time. Yeah u still have the Dumb part of the dumb bombing, but it's close enough. Thanks a lot. :thumbup: [sIGPIC]][/sIGPIC] Fuel Planning Tool | DCS: A-10C SADL MOD | Kimi's Arma 3 Mods | Twitch.tv Link to comment Share on other sites More sharing options...
ricktoberfest Posted February 10, 2015 Share Posted February 10, 2015 Maybe I'm expecting too much accuracy with mk82s level bombing. I can't search well on my phone but I can make a track where level flight CCRP below 6000', the steering cue starts stable, but then veers just when you should be stabilizing for release.

I think the 2 times coefficient, has nothing to do with the unit conversion. My english is poor,can you understand me?

Darkenmass Posted March 31, 2015 Share Posted March 31, 2015 2x It's 2X because the this is the way engine calculate wind speed, it's not a natural phenomena, it's a computed one, so if at 10m altitude you have 10m/s wind at higher altitude (eg. 500m ) you get the DOUBLE so 20m/s until you reach the next layer at 2000m. I get confused by this too, and i slightly changed the excell program setting it a 2.2 coef. at 4000ft. But i still don't know if i did it right, probably not. "Blow wind blow...." Tom Waits....

WildBillKelsoe Posted March 31, 2015 Share Posted March 31, 2015 JTAC measures wind at zero level. Not sure if dynamic weather systems zones share the same as ATC wind measurement. I'd love to be wrong. AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower.

Yurgon Posted April 1, 2015 Share Posted April 1, 2015 Wish we had the ability to see the wind as CA player acting as JTAC... You can, indirectly. As long as there are factories or chimneys in the area, it should be possible to estimate wind direction and strength from their smoke, or you could use Willie Petes for the purpose. OTOH, from the cockpit perspective I usually need to see at least two chimneys/smoke columns because from most angles it's very difficult to see which direction the smoke actually blows. Still, might be worth trying. :thumbup: Link to comment Share on other sites More sharing options...

Boris Posted August 10, 2015 Author Share Posted August 10, 2015 and doesn it record values after having flown through the layers into the cdu laste? There are different layers of wind. You will get an automatic adjustment for the wind at the altitude that you drop the bomb at, but it won't adjust for any of the layers the bomb falls through. That's why you have to go through the steps as I described for maximum accuracy. 2 PC Specs / Hardware: MSI z370 Gaming Plus Mainboard, Intel 8700k @ 5GHz, MSI Sea Hawk 2080 Ti @ 2100MHz, 32GB 3200 MHz DDR4 RAM Displays: Philips BDM4065UC 60Hz 4K UHD Screen, Pimax 8KX Controllers / Peripherals: VPC MongoosT-50, Thrustmaster Warthog HOTAS, modded MS FFB2/CH Combatstick, MFG Crosswind Pedals, Gametrix JetSeat OS: Windows 10 Home Creator's Update Link to comment Share on other sites More sharing options...

Yurgon Posted August 10, 2015 Share Posted August 10, 2015 Actually this starts to feel like cheating. I've had CCRP Mk-82s in a high-wind-environment hit bullseye from Angels 24, often better than GBU-12 with 10 second lasing or GBU-38 under the same general circumstances. :D Link to comment Share on other sites More sharing options...
