• ADS EMERGENCY – sends an alert to ATC indicating an emergency
situation (resets to ADS EMERGENCY OFF at power-up)
• ADS EMERGENCY OFF – cancels emergency indication to ATC
A list of ADS connection status is displayed on the ADS page.
A select key is available to terminate any active air traffic service provider (ATSP)
facility ADS connection. Selecting the adjacent DISCONNECT key causes a
disconnect message to be sent to the associated ground station.
A select key is also available to INHIBIT/ENABLE an ATSP from establishing an
ADS contact with the airplane. Entering the ICAO identifier of the ATSP into the
data box and selecting INHIBIT prohibits an ADS connection from that facility.
Entering the identifier of an inhibited ATSP and selecting the ENABLE box
allows a connection to be made with that facility. Only one ATSP can be inhibited
at a time.
The lower portion of the ADS page displays system status messages.
