ATCx [5R]:
Used to display and modify the ATC active and standby codes from the current active transponder
or from the last active transponder when toggled back to standby mode. Default value will be the primary
transponder at power-up (cold start) when both transponders are in standby mode.
NOTE: ATC Radio equipment name can be configured as “ATC”, “TPDR” or “XPDR". The case displayed
above is the “ATC” configuration.
When configured to prevent FMS tuning of the ATC transponder (ATC CONFIG 2/X LSK 5R) and the

modification of the data (e.g. standby code) by displaying !MC IN CONTROL data advisory scratchpad
message.
