Default EZ 42 gunsight

As i understand, from a set based on Gunsight's gyro power switch "On", Gunsight ballistic adjustment unit Rotary "I" and Target wingspan knob and wait for 1.5 minute, adjusting twist grip for range selection should predict where the bullet will arrive.


Doing so, flying on level, i'm surprised when arrived at last step, twisting grip for range don't make the reticle circle moving up or down depending of the target distance. So, under 700m all bullets goes above target, and beyond 700m under target. Different behavior on moves as cross goes up or down depending on target distance (using throttle grip).


So, is it right to say that deviation depending on target distance is only "calculated" by EZ 42 on moves (up or down, left or right, etc) and not "calculated" by EZ 42 flying straight ?

'flying Straight" will still result in in Gyro calculation based on Set target range so in this case Gravity drop and a fixed value of trajectory shift based on speed/Altitude i.e TAS component also input to the sight via the thumb wheel controls in a separate box.

I cannot find any mention of a TAS adjustment. There is an adjustment for altitude though ( Altitude Aiming Correction). Unfortunately, the values indicated in that box on the right are are not legible and the thumbwheel rotates with lightning speed. So this adjustment is essentially useless.
@ED: You should give us a legible table of altitude settings, and you should unblur the box in the cockpit. And you should reduce the gain of this adjustment.
Edit: found the table in the texture file "fw190cpt_part06.dds". And yes, of course there is a path from altitude and IAS to TAS.
And another note to ED: when you start a mission the default setting is 0 which corresponds to no realistic altitude at all. Since it is so hard to set, the default should be 93 or 94 since most fighting is below 4 km altitude.
Of course, I don't know whether this adjustment has any effect in the sim. I might just be wasting my breath.
Edit: I have now reduced the gain in "clickabledata.lua" from 0.1 to 0.01, and now the thumbwheel can be adjusted with some accuracy.

This is not currently the case, so can we consider it as a bug to be reported ?

Gunsight's gyro power switch "On", Gunsight ballistic adjustment unit Rotary "I" set to 100 (or 90 or whatever) and Target wingspan knob set to 11.2 and wait for 1.5 minute,
twisting grip for range gives this:

The Altitude adjustment is I believe the input for the TAS adjustment ... talking about Bullets TAS to be used in the computation. Since Mv is known. So Altitude affects Bullet TAS which affects Tine Of flight so therefore lead required.

That I believe is in fact a Bug then. Range obviously affects Gravity Drop and is independent of G or turn rate.

Will raise in the internal Bug sheet
