--I tested the sight in the TA with two volunteers and the sight works best for speeds around 275mph.
--The 3 horizontal lines are the starting references for level (10 degrees) attack, 45', and steep vertical attack (< 90') to start reading the dots from bottom to top.
--Each point in the V are in 200yards increments, thus the 8 and 4 marks mean 800 and 400yards to have a quick screen-to-brain process. However, these numbers use the lower horizontal line as reference (hence during a shallow angle attack). The points are closer at long range and farther appart at close range to aim each wing sides.
--The two vertical lines from 600 to 200 range is the sweet spot. Also, the small point pairs on it show the lateral displacement required for 1k shots both for 45' and 90' angle attacks (from bottom to top).
--The inverted T in the Center is for aiming guns obviously but the bottom is hidden to see the bullet stream for long range shots.
So for example the ennemy tank is at 800, you are level, and your left wing rockets are ready to fire: just aim the left point next to the 8 right on the tank and shoot.
I did this pretty fast and everything can easily be modified. I will post a picture practicual example shortly.
EDIT: Of course it is cluttered but its best used while zoomed on the tank. I never shoot tanks unzoomed so for those that dont zoom, use the larger horizontal lines and aim on the fly. Also, the 190F8 is not a really good dogfighter so the sight is best used for ground support.
