ATC1 [1L]:
Displays and allows modification of the active and standby identity code for the ATC1 transponder.
Enter identifier in scratchpad and press LSK 1L. Entry may be made to the standby position only when a new
value is in the scratchpad. If the scratchpad is empty it toggles between active/standby identifiers.
When a radio has been tuned to a new code from a remote control unit (RCU) and the radio is capable of providing
tuning feedback, the new code is displayed in the active field and the current active code is moved in the standby
field. This way, consistent setting is displayed on both control units.
The FMS displays a tuned active code in large font white color. During the tuning process, the active code is
displayed in large font inverse white color. If the tuning operation is not successful, the code is displayed in small
font amber color as a warning to the pilot. If an EMERGENCY request is made when this field already showing the
active code in amber, then this field will change to show the active code in inverse video amber font.
For S/W 300V and higher:
When the ATC is transmitting the “IDENT” pulse (refer to 5L below), the following rules apply:
•
entry of an ATC code in the standby field is allowed only for emergency codes
•
toggling the standby/active code is allowed only if the standby code is an emergency code
For non-emergency ATC codes, the FMS will display an advisory message (!NO ENTRY ALLOWED) to inform
the user that the FMS cannot accept the command.
ATC2 [1R]:
Same
as above, but referencing ATC2 instead of ATC1 and LSK 2R instead of LSK 1L.
NOTE: For ATC1 and ACT2 it is possible to have "-" in one or both of the active and standby fields after FMS
maintenance. At that time, a code needs to be entered in the standby position first before the
active/standby field toggling is allowed, otherwise a warning message will be displayed in the scratchpad.
MODE C [3L]:
Toggles ATC1 SSR Mode C functions for the ATC radio. The possible values are ON and OFF.
MODE C [3R]:
Same
as above, but referencing ATC2 instead of ATC1.
NOTE: New code and setting are accepted when the radio is in "STANDBY" mode, but the tuning of the radio
to the new code and/or setting will only occur when the radio status will be set to "ACTIVE"
STATUS1 [4L]:
Displays the activity status of the ATC1 transponder. Pressing this softkey selects the next
option. The possible values are ACTIVE and STANDBY. The STATUS1 is automatically switched to ACTIVE
on a transition from ground to airborne and is automatically switched to STANDBY upon a transition from
airborne to ground. Only one ATC unit can be active at a given time, therefore making one of them active will
cause the other to become standby.
STATUS2 [4R]:
Same
as above, but referencing ATC2 instead of ATC1.
IDENT [5L]:
Allow the crew to add the Special Position Identification "IDENT" pulse to the ATCRBS Mode A
reply code on the ATC radio which is "ACTIVE". It is possible to re-initiate the "IDENT" at any time, including
when it is already being transmitted.
EMERGENCY [5R]:
Displayed in large font green when the configured emergency code is not 0000, otherwise
the field is blank. Pressing this softkey transmits the configured emergency code to the ATC and sets the
transponder status to active. Displayed in large font inverse green as long as the active code is an emergency
code and the radio is active.
NOTE:
Activation of emergency mode on ground will only be possible if the ATC ON GND configuration option
on the A429 ATC CONFIG 1/2 page has been selected.
RADIO [6L]:
Access to the RADIO top level page where the ATC transponder is located.
CTL [6R]:
Available only when the transponder is configured to be controlled by either the FMS or an external
Mission Computer, otherwise this field is blank. This field displays whether the FMS or the Mission Computer is
in tuning control of the transponder. The crew can tune the transponder from the FMS only when the FMS is in
control.
