problem to see enemies at 5km

[rollnloop]

Standard for first pixel is 8km for fighters, slightly more for bombers.

AA tends to blur this pixel, especially below horizon (except with winter terrain), so keep low AA, and give one more notch in res if you want less jaggies.

Main problem is usually at 1000m, down to 300m, when contact is below and same general color as background. Not much to do for this, except maybe a very big monitor (30" ?).
