Official way for tower to address all aircraft on frequency for new ATIS?
The tower will usually broadcast a note such as “Attention all aircraft: ATIS information Victor is now current. Wind two two zero at seven knots.  Altimeter three zero one four”.  This isn’t official phraseology and really isn’t required of ATC, but is a courtesy call to all pilots operating around the airport to retrieve the latest ATIS broadcast for reference.
