Considering that a value = 60 represents an altitude of 1o...12 km, this would correspond to an altitude in the upper stratosphere (25,700 m) with fairly low air density. With that given, the TAS calculation would result in a huge true air speed which would result in an almost straight line as the ballistic curve.
All speculation of course as we have no clue how the calculations are implementated.
ED please give us clarity!

Talking

You must set the Gunsight Rotary "I" Ballistic Adjustment Unit to your flight level, even if, for the moment, the changes are not as "visible".
Indeed, strange speculations ... what happens in case you set Rotary "I" to its max : 180 ?

Is this the reason I can't hit a damned thing with the Dora?

WHY this isn't in the FW190 official dcs manual??? I didn't know that this was modeled. There are more things modeled in the aircraft that aren't mentioned in the flight manual?


Also there's a manual for the EZ 42 Adjustment panel box?

(Lixma)A reason till 700m you always have to shoot (aim) under your target.

(Wolf)Yes, it is in the FW190 official dcs manual (En) page 56, 57, 58 and 59

Looking at the K14 it exhibits the same problem in that GD is not changing with range either. Will post some details here as well and bug report both sights internally.


The Diagram below is for the K14/Gyro GS MKII illustrating the test procedure and illustrates what happens to the Pipper with range changes and the correction for Gravity Drop at 1G. There is also extensive notes in the source publication on exactly how the GD correction is made and how much. The EZ42 should behave in a similar fashion. So in the case of the EZ42 you should see the Gyro reticule drop as range is increased. You dont in the Sim as found by Scoll

The Adjustment box table is specific to a type of aircraft and weapon fit. The way its intended to be used is the pilot notes his altitude in KM then sets the knobs A and B in accordance with the table in the image below (from a translated German EZ42 Manual D.(Luft) T.g. 6413) the knobs have been set for an altitude of 6Km so Tumbler A at 76 and Tumbler B 40




The description from the translated EZ42 manual :



Perhaps this is all moot anyway since in DCS only tumbler I is adjustable anyway .... Though the lack Gravity Drop correction with range is I believe valid

Internal bug reports for both EZ42 and K14 not adjusting for gravity drop with range changes submitted.

Could you reduce the gain on the altitude adjustment rotary as LeCuvier mentioned - it's impossibly fast.
