Wojtus,
Our ATIS is semi-automatic. Whenever we input runway condition,IRVR or braking action it will always broadcast it as touchdown/mid point/stop end for the runway in use.
If, whilst runway data were being broadcast, we were to change runway to the opposite end, then I would only have to input the change of runway and the runway state would be automatically reversed to the opposite end.
For example runway 12 surface wet/damp/dry. If it were decided to switch to runway 30 then I would input the runway change and ATIS would automatically broadcast surface dry/damp/wet.
My company uses a Muir Matheson SAMOS system. Other systems may well be different.
