Stepbrother, your EO sensors have enormous range!

Interesting suggestion, thanks. Added to our stack so that we can take a look at this when possible.

Bonus points if you can draw the contrails on the screen with an associated radio call.

There exists a contrails-specific radio call?

There exists a contrails-specific radio call?

See AFTTP(I) 3-2.5

"MARKING Informative call indicating friendly aircraft is leaving contrails. (NOTE: NATO term in CONNING)"
"CONS/CONNING Descriptive term for nonfriendly aircraft leaving contrails."

You refer to friendly aircraft marking, and bad guys as "CONNING" or "CONS."

My brevity is really terrible, so I'm sure someone more knowledgable than me might correct my examples, but here goes:

Examples:

"TALLY CONS"
"TALLY HOSTILE CONNING moving left to right."

"EAGLE 3-1, VIPER 3-2. You're MARKING."

EO range:

Are atmospheric obscurants modeled, or is it a pure geometry calculation? (E.g., height of observer, radius of curvature/physical horizon, height of target.)

Obviously cloud layers are important, but far more prevalent would be humidity.

My daily drive has a view of a peak 29 miles away. Some days, it is clearly visible, other days it is slightly obscured (a bit of a grey veil), and on still others it is totally invisible. The visibility is due solely to relative humidity.

I know there are sensor reductions based on weather state (cloud and rain states), the exact figures matching what rain and or cloud state get interesting, I don't know offhand for CMO but during the CMANO days I posted what some of the reduction percentages were buried in this thread. Gives you some idea even if it's not exact.

For anyone still interested on this. One of the (very few) new things we added on the big upcoming update is optional indicators for aircraft contrails and ship/sub wakes:

Cool feature, is the contrail prone flight level defined by fixed values, or is it variable? Will it be visualised by the Altitude and Speed window?

Piece in Popular Mechanics on SOKS, "System Obnarujenia Kilvaternovo Sleda" or "wake object detection system".

I see they are in the database in two versions, 1960s and 2010s.

On contrails; according to the MegaFAQ contrails form at altitudes larger than 8000m and temperatures of -40°C. To my understanding this condition was/is not modelled other than contrails being present for all altitudes higher than ~28000 feet.

I like this a lot. Another thing to have to take into consideration when detecting/avoiding detection!

That may be worth revisiting, once the more urgent things have been dealt with.

Contails are a type of mixing cloud, so doing something beyond having them appear above fixed altitudes would require the game to include information about the temperature and humidity of the aircraft exhaust together with the temperature and humidity of the ambient air surrounding the exhaust. Unless customers of the professional edition are really clamoring for something more, this would be overkill for CMO. It may be plausible to make some limited adjustments based on game weather settings.

The cloud produced when you exhale on a cold day is another type of mixing cloud, so this cloud is in some sense a ground-level "breath contrail".

Very cool to see this has been added!

Thanks.
