There is another thing I don't understand:
The table says for N.O.E.
500m / 15 MIL
1000m / 0 MIL
1500m / -25 MIL WHY?
2000 / -15 MIL
2 Reasons, why I think it is wrong:
1) those MIL-steps to change the target range by 500m are round about 10-15 MIL = round about 1 Deg = mathematically "nothing"
that means in this range (500-2000m) MIL is nearly linear proportional to range
So how can 1500m be correltated to -25MIL and 2000m to -15MIL when at the same time 1300m is also -15MIL?
Conclusion: This is a magic helicopter, that, with a single shot at –15 MIL, hits a target both at 2,000 m and at 1,300 m (interpolated)
I am sure no one can explain this table with a mysterious point of discontinuity or a dualism, like wave and particle.
2) I tried it out in DCS and it was difficult to freeze the heli in a locked on position
Then I watched my projectiles fly in F11
My estimated empirical values are roundabout:
500m / 20MIL
1000m / -8MIL
1500m / -10MIL
2000m / -12MIL
2500m / -15MIL
I can confirm, there is a nearly linear correlation between MIL and range - the table is wrong.
Final conclusion: you dont need an accurate pilot's targetsystem anyway...
WHY?
1) obviously it doesn't work correctly
2) the values as listet in the table are wrong
3) in reality there is no time to calculate and play around with dials
4) the helicopter is shaking while targeting way more than your 500m MIL-steps
5) if you can see a tracer, then just follow the track - at the end hopefully lies the target
For the gunners reticle: don't care - you have a spray gun that hits everythig everywhere.
