Automatic Terminal Information Service (ATIS)

ATIS is an airport information short range transmission, broadcast in the VHF band of frequencies, which contains essential information about conditions at the airport.

We'll use Venizelos' ATIS broadcast from 19/10/2007 as an example.

This is the transmission that was broadcast on frequency 136.125 MHz:

Here is Athens Venizelos airport ATIS information Delta, recorded at 1320.
