[OT]
We did make several runs yesterday at different altitudes in the He-111 H-2 and everything is working as intended so far. We observed that the bombs fall and exploded in the correct order, the spacing was also correct, that makes me believe that not only the sight, but all the code has been completely revised. Tests done up to 3.500 m so far, with one human in pilot's seat and another in the bombardier. Smooth as silk. This patch is a milestone in COD's development.  [/OT] David, we have in our squad a wing of dedicated pilot for bombers, if not I would gladly join you. BTW, how about some joint ops between you ad us guys? S!

Yes, it probably needs you to input TAS now as a starting value, i think it was ATAG_Keller who confirmed this in another post. And i say starting value because in reality, what matters in bombing is GS (ground speed, or how fast your are actually going compared to the ground).
I usually do it the old fashioned way a la IL2: just set the altitude, start from the IAS or TAS value and engage automation. Since your actual ground speed is higher than IAS and closer to TAS (but not always equal, eg, it could be lower than TAS in case of a headwind), you will see that the sight is drifting above/below the target (it can't compensate because it "thinks" the plane is going slower/faster than it really is) So, i simply increase/decrease bombsight speed in small steps until the crosshairs stops drifting, recenter it on the target and wait. Essentially you are using the sight's tracking mechanism to "discover" you ground speed

no need to fly on atag exclusively....we now gave 71st squad our missions to run on their server which is now called something like 71st-ACG combined server....historical missions with a nice historical map template,good ai,...certainly an alternative to atag.

He-111 bombsight seems to be working well with 8 x SC 250kg bombs, more testing required with the 50kg bombs.
I have done 4 bomb runs with the 250's at varying altitudes (4200 - 5500m) and the bombsight was right on target, the one run I did with the 50kg bombs from 4500m fell well short of the target.

If that were the case it real life, how was the bombsight programmed to know what bombs were on board? Another thing I should mention is that I don't feel that the damage from the bombs is high enough. A 250kg bomb should do much more damage than it currently does.

The trajectory adjustment was manual in the real bombsight. Ours is automatic to simplify things a bit, otherwise we'd have to enter data from tables according to airspeed, altitude and bomb type.
The advantage of how it's done in the sim is that it's simpler. The advantage of the real bombsights is that an experienced bombardier could probably enter an in-between value to account for different types of bombs on board. I think the best way to account for this in the sim is to experiment, accept that that we should be going after area targets (factories, airfields, etc, no more hitting a handful of vehicles from 3km) and get a couple of wingmen. The SC 50s don't miss by much, they just drop a couple of clicks down from where the bombsight aims, so it's easy to account for it. I don't know what happens if you select a bombload with one bomb type only though. Maybe loading only SC50s uses the trajectory adjustment more suitable to them, but i haven't tested this yet.

@David, great I will contact you (through sandokito). @Blackdog: yes your method is good and works. Just to have another in your bag of tricks, if you plan to use precalculated TAS, I confirmed that if you calculate TAS taking OAT (outside air temperature into account) into account, the results are perfect. Here you are a good resource for doing the maths: http://www.luizmonteiro.com/Altimetry.aspx#TrueAirspeed So in your bombing run, switch to your pilot position, and check the OAT in your upper left panel, input that value and correct the TAS with the deviation from the standard atmosphere. Now, the wind. As we know, we have to correct the TAS with the front component of the Wind speed to obtain GS. But another thing I noticed in my test ( and I believe that the devs modelled ), is that because the form factor of the bombs and the aircraft are completely different, and the trajectory of the bomb makes it face the wind in the worst aerodynamic manner possible, the effect of the wind on the bombs can not be estimated as easy as using GS as input. If you use GS the bombs will fall short. Unless the devs model a drift compensation, it needs to be tabulated. You have to lower it a little to compensate that effect, in my tests 15 km/h for 10 m/s and 20 km/h for 20 m/s wind, but take that values as a start point as I did not have the time to measure them precisely. Bear in my mind that this was for a mission with 250 kg bombs, a constant flow of wind from surface to 10 km, and no gusts and no changes of wind directions. If you program a mission with all these possible features, the thing gets more and more complicated. I agree with Keller that IMO the 250 kg bombs should do more damage- Did not test the 50 kg bombs yet, but I think as Blackdog that you have to compensate manually and build tables from experimentation. Very happy with the sim now.
