RTS354 Posted February 16, 2024 Posted February 16, 2024 I'm trying to drop CBU 97's from the F-16C and it seems like the wind is blowing the bomblets off target. Is there a way you can program the wind direction and speed into bomb calculation?
Solution razo+r Posted February 16, 2024 Solution Posted February 16, 2024 No, you have to manually adjust for it or take the CBU-105 instead. Dobber switch right on the main page of the DED shows you the wind direction and speed. 2
void68 Posted March 26, 2024 Posted March 26, 2024 (edited) Set BA to 800-900', so "wind exposure" time is at minimum. Check the "bomblet chuting down time from different BA" by observing the Weapon view. Below 800' the CBU might dud. Check wind speed and direction (at 0' AGL, not always easy to check, but then take the wind at your current altitude). Then for every second of "exposure time" you add (approx) half the knots in windspeed in meters / 3,28x foot windwards. That's your new aimpoint. Example: 20kts for (lets guess:) 10s chuting down with wind from 0° = 20kts x 0,5 x 10s = 100m / 328' north of the target. Either do a VRP / VIP for a reference, do some quick maths to shift your long/lat coordinates 100m (cosinus in it, have fun ) or do a rough educated guess either with your TGP for CCRP or your eyeball for CCIP. CBU-97 in high winds is no real fun, best is doing a <=1000' spacing between two serial released bombs right into lee- or windward and aim for the center. If I remember correctly the burst pattern is 1000' long and 300' wide so with a reasonable BA you don't have to worry about even the strongest wind, 10s chute time x 0,5 x X = 2 bombs x 328m <-> X = 2x 2x 328m/10s <-> X= 128 kts. 64kts is 12 Bft. 128kts is a windspeed you might face on Jupiter, I think, not on earth. Just an extreme example. So a single CBU dropped directly from lee- or windward direction will help a lot due to the shape of the explosion ellipse. Is there a mistake in my calculations? If not you can "translate" that into offset angles, again with trigonometry. Two updates ago when the CBU97 was bugged you can imagine how much anger I built up when my calculations just did not match DCS' math... Edited March 26, 2024 by void68
