• Provide a resolution advisory (RA) that _________

alerts the pilot to traffic that may be a conflict, gives the pilot a means to avoid the conflict

TCAS I includes _______. It is capable of providing _____ to help the pilot visually acquire intruder aircraft and avoid potential collisions.

a computer and pilot display, traffic advisories (TAs)

TCAS I can provide both TAs and RAs.

False

TCAS II includes _______. It is capable of providing _____.

a computer and pilot display and a Mode S transponder, both TAs and RAs

Resolution advisories (RAs) include a means of avoiding the conflict ______, by either ____ or ______ separation between aircraft.

vertically, increasing, maintaining existing vertical

There is TCAS equipment capable of providing lateral RAs.

False

A TA alerts the pilot of traffic that may be a conflict, whereas an RA gives the pilot a _____.

means to avoid the conflict

If TCAS identifies a potential collision hazard, it will either issue a TA or an RA. What does TA stand for?

Traffic advisory

TCAS II include 4 main components:

Transponder, computer, display, speaker

A transponder is an aircraft receiver-transmitter that sends a coded signal to _______.

ground-based equipment and aircraft TCAS equipment

The information sent from transponders allows operational personnel to view the aircraft on _______. It also allows pilots to view information on TCAS displays, with varying levels of information depending on _______.

surveillance displays, the mode of transponder

To receive a TA or an RA, ______ must be equipped with operating transponder(s).

both aircraft

The transponder has 3 modes:

Mode A, Mode C, and Mode S

Mode A transmits ______ that allows _______ to display a target (without altitude information)

an identifying code, surveillance equipment, but not TCAS equipment

Mode C transmits the same information as ______, plus ____, for display on _____.

Mode A, aircraft altitude, both surveillance and TCAS equipment

Mode S transmits the same information as _____, plus it permits _____.

Mode C, data exchange between aircraft

The TCAS computer unit performs _____. It also keeps track of its own position as well as that of the intruder aircraft

airspace surveillance, threat detection, and resolution

The TA display shows the position of the traffic ______ to assist the pilot in visually intruding aircraft. It may be a dedicated display or part of the ______ display.

relative to the TCAS aircraft, weather radar

The RA display indicates whether the pilot should initiate _______, as well as the _____ that must be achieved to increase separation from threatening aircraft.

a climb or a descent, the vertical rate of climb or descent

When a TA is issued, the TCAS computer will announce ______ to direct the display to look at ______ to locate the traffic.

“TRAFFIC, TRAFFIC”, the TA display

If the TA does not resolve itself, and the aircraft is equipped with _______, the computer issues an RA and announces either _______.

TCAS II, "CLIMB, CLIMB, CLIMB" or "DESCEND, DESCEND, DESCEND"

When the conflict has been resolved, the TCAS computer announces:

“CLEAR OF CONFLICT”

Where is TCAS equipment located?

Entirely on board the aircraft
