New
messages can be prepared ready to transmit, and listened to,
without affecting the current broadcast. Wherever possible
message content is created automatically, for instance meteorological
data can be sourced from an AWOS or AFTN, with manual updates
to the other airfield information, using the previous message
as the starting point to minimise the workload. |

The
system is fully compliant with ICAO recommendations with message
content checking, and a transmission archive. It is normally
operated in a semi-automatic mode (where the operator is alerted
to the need for a new broadcast each time a new met report
is received or a configured time interval has passed since
the last update) although it can also operate in fully automatic
mode without the need for operator intervention. There is
also a pre-validation option (to suit some local safety regulations)
requiring that each announcement be heard prior to transmission.
A
telephone dial-in option allows local GA pilots to listen
to the ATIS before setting off to the airfield.
D-ATIS
is also available using a datalink service provider such as
ARINC or SITA.
