we don't think it is the ATCO's.
We know its some office blunty who dictates what's on it. Who then add things thinking its a good thing but don't actually realise that.
a) it will be forgotten
b) the crews really don't care about the extras.
Most crews should get the ATIS just after the change over. If you put a special through after that more than likely they won't.
And the ATIS code thing is another thing special to the UK in Europe some days I am the only one that I hear giving it on frequency into a National Capital multi runway airport. The only others who regularly give it is speedbird.
And yes I have worked none ATIS. But in general if the cloud base is above 1000ft agl, the wind is under 15knts, your not into RVR's, your using the into wind runway all the pilots care about is the QNH for single runway airports and Runway in use and QNH if into a multiple runway airport.
You could give it "information Alpha, its lovely, QNH 1003" for all the use we make of the ATIS broadcast.
To be honest the military colour code system is a cracking way of dealing with it.
