Dewpoint on ATIS
-
Did the team leave off dewpoint because just because humidity isn’t simulated or to also keep the ATIS shorter?
Just saying, you could always work the good old temperature/dewpoint spread to cloud base formula backwards to get a dewpoint so it’s not missing if it is desired for ATIS purposes.

My guess is cause it is supposed to be realistic. All ATIS/METAR comes with dew point in RL.

Exactly, so why not add it in using the formula? I get you kinda have to fudge it if the sky is clear. Maybe make a standard offset of 10 degrees or then add “dewpoint- missing” as ASOS/AWOS would say. Although, I honestly can’t remember if that is how an automated ATIS works if dewpoint was unavailable from the sensors, probably they make the junior guy go out and use the sling psychrometer so they can still type it into the text to speech engine.
As the Comms guide states:
The missing information is the dew point, normally following the temperature. It is an important factor as the difference between temperature and dew point warns about the water saturation in the air and thus the possibility of Fog.
Agreed, it is important for fog and humidity, but it is a little more in that it can also be used for the estimate of cloud base. As I’m saying, you can use the rule of thumb formula to get an about as accurate as real life data since all the sensors that feed into the ATIS are rarely exactly right on cloud base and the real life differences in lapse rates in temperature and dewpoint are not standard as the formula assumes. So using this method, while a little foggy:D , would create numbers about as accurate as real life since their is a little GIGO there too.

AFAIK, RL MIL airbases never have an ATIS due to OPSEC, so for realism’s sake, we should actually remove the ATIS and ATC should announce important information (active runway, QNH, anything else significant) on first contact.

The base I work on has ATIS, but I think it has operating hours - not 24/7/365.
Yes - ATIS should include not only RH and dew point, but also freezing level.

Yes, I looked at it and most of the CONUS and South Korea have ATIS freqs with a mix of UHF and VHF. I get OPSEC in wartime they could be shut off, but definitely a thing for training environment.
And yes, I forgot those are extra things over civilian airports that would be in military ATIS/TAFs.
