SUPERAWOS AUTOMATICALLY GREETS INBOUND PILOTS A few signs on the ground at the airport will only be seen by a few departing pilots, and FAA publications are like wine, they seem to improve with age. To let pilots know about the system and how to use it, Pilots first coming to an airport with a SUPERAWOS® the system actually recognizes communication patterns on the unicom frequency and, when called for, offers inbound pilots an informative Greeting Message in reply to their transmissions. When the frequency is clear enough it will even greet pilots and give them an advisory:
PILOT "Hello, hello XYZ Airfield. Anyone in the pattern at XYZ?.. Requesting an advisory....
AUTOMATED GREETING WHEN THE UNICOM IS QUIET
SUPERAWOS "Good morning, this is XYZ Airfield, Automated Advisory, Visibility better than ten miles, wind 320 at 16, altimeter 30.22,
(detects & replies) Caution Crosswind, Conditions favor runway 24; for runway, listen for traffic."
(Off-frequency pause to allow others to respond)
"For further services, click your mic 3 times for an Advisory, 4 times for a Radio-Check"
AUTOMATED GREETING AS THE UNICOM GETS BUSIER -
"Good afternoon, this is the XYZ Airfield, automated unicom,
click your mic 3 times for an advisory,
4 times for a radio-check."
This message recognizes and responds to an inbound pilots call to traffic. As the frequency gets busier, this Greeting Message occurs less and less often, disappearing entirely during times the frequency gets busy and it might be intrusive.
The airport manager can selectively tune how relatively often the Greeting occurs, to accommodate the type of traffic particular to your airport: An airport with mostly transient traffic needs the Greeting more, with mostly itinerant traffic, where pilots are already familiar with the system, the Greeting is needed less.
