This is determined without any supposing at all. It is found out using only IL2/FB graphics yet without resorting to pixels or any esoteric sleight of hand.

Straightforward:

A) Line up behind a friendly FW190-A4 at 200m and see the wings fill the ring. The wingspan of the A4 is 10.52m according to the object viewer. I assume there is no mistake there.

B) 10m wide at 200m away is an angle of 2.86 degrees.

C) The ring itself has a crosshair marked, 3 segments for one radius of the ring. The radius is 1.43 degrees. At 2 decimal places that is accurate.

D) Each segment is 1.43 degrees / 3.

E) From the bottom edge of the ring to the bar is 2 segments. Total segments from center of revi crosshairs down to the bar is 5.

F) 1.43 degrees * 5 / 3 = 2.38 degrees.

G) Downward view through the revi is about 2.38 degrees and NOT 3 degrees or 4 degrees as we have been told.

There are NO tricks here. Everything is from the sim itself and anyone can find this out with just a little trigonometry of the high school level.

Tangent of 1/2 the view angle is 1/2 width of the circle divided by range to that width. 5m/200m = 0.025. Tangent of 1.43 degrees = 0.025. View angle from crosshairs center to edge of ring is 1.43 degrees. There is no trick.

*** FW says 3 degrees is visible. The difference may only be .62 degrees but that .62 is over 20% of those 3 degrees. From Oleg says 4 degrees is visible the % less is much higher.

Check the numbers, check the view, and ... Be Sure!
