AIR TRAFFIC CONTROL (ATC) TRANSPONDER SYSTEM (CONT'D)
ATC Transponder Control – MFD Tuning Block
ATC control may also be carried out from the MFD tuning window. The top level TCAS/ATC 1
(2) menu of the MFD tune display includes selections for the active ATC code, mode selection,
and altitude limits selection (TCAS only). A combined ATC/TCAS submenu is also available,
providing similar functions as found on the CDU ATC/TCAS control page.
The cursor control panel includes several buttons providing input to the ATC system, and
controlling the focus indicator on the MFD tuning window.
• RADIO button – Used to access the ATC submenu on the MFD tuning window.
• FREQ – Used to position the focus indicator around the active ATC code when it is
located within the TCAS/ATC block, but does not surround the active code.
• 1/2 button – Enables cross-side control of the opposite ATC transponder.
• IDENT button – Used to select transponder ident for the active transponder.
• ATC button – Used to change the transponder/TCAS from standby to RA/TA, and from
any state to standby.
• RADIO/DATA/ADV knob – Used to navigate through the displayed ATC submenu.

ATC Transponder Control – TCAS/ATC Submenu
The combined TCAS/ATC 1 (2) control submenu is accessed using the RADIO ADV/DATA
and RADIO button on the cursor control panel. Active mode selections on the submenu are
indicated by enlarged cyan text.
From the submenu, the crew can carry out the following ATC functions:
• Set the ATC code.
• Identify the ATC altitude source (ADC 1 or ADC 2).
• Select the active ATC (1 or 2).

TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS)
Description
The TCAS is an airborne system that interrogates other aircraft’s ATC transponders to identify and
display potential collision threats. The system protects a volume of airspace around the aircraft,
and provides aural and visual advisories when intruding aircraft penetrate that protected airspace.
TCAS monitors a radius of approximately 5 to 40 NM around the aircraft. The TCAS transceiver
transmits mode-C and mode-S transponder interrogation signals, and monitors all replies. Internal
processing determines the range, bearing, and altitude of each transponder-equipped aircraft
within range. When a conflict exists, the TCAS generates traffic advisory (intruder alert), resolution
advisory (recommended vertical escape maneuver), and/or synthesized-voice audio outputs.
When an intruder aircraft is also equipped with a functioning mode-S transponder, the TCAS uses
the transponder to transmit collision avoidance data to that aircraft. This mode-S link allows the
two TCAS systems to coordinate conflict resolution between aircraft.
TCAS Transmitter/Receiver
The TCAS transmitter/receiver contains the TCAS computer, and is installed in the underfloor
avionics compartment. It selectively transmits interrogation signals, receives and analyzes the
responses, determines if potential conflicts exist, generates collision avoidance solutions, and
formats the data to visually and/or aurally present that information to the pilots.

TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS) (CONT'D)
The TCAS transmitter/receiver receives bearing information from the TCAS directional antenna
on the top of the fuselage, and receives altitude information from the TCAS omnidirectional
antenna, located on the underside of the fuselage. Power for the TCAS transmitter/receiver is
supplied by the AC essential bus.
TCAS Controls
TCAS controls and mode selections are done on the FMS control display unit (CDU), or on the
CCP/MFD radio tuning window. The displays and controls of the TCAS and ATC radio are
combined.
