SYS 5 - 3

The TCAS (Traffic Collision Avoidance System) gives avoidance resolutions:

• in horizontal and vertical planes

• only in the horizontal plane

• only in the vertical plane

In the event of a conflict, the TCAS (Traffic Collision Avoidance System) will give information such as:

• climb/descent

• turn left/turn right

• too low terrain

The principle of the TCAS (Traffic Collision Avoidance Systems) is based on the use of:

• airborne weather radar system

• transponders fitted in the aircraft

• F.M.S. (Flight Management System)

The TCAS (Traffic Collision Avoidance System) computer receives information: 1- about the pressure altitude through the mode S transponder 2- from the radio altimeter 3- specific to the airplane configuration 4- from the inertial units The combination regrouping all the correct statements is:

• 1, 2, 3, 4

• 1, 2, 3

• 1, 2, 4

When the intruding aircraft is equipped with a transponder without altitude reporting capability, the TCAS (Traffic Collision Avoidance System) issues a:

• "traffic advisory" and vertical "resolution advisory".

• "traffic advisory" only.

• "traffic advisory" and horizontal "resolution advisory"

On a TCAS2 (Traffic Collision Avoidance System), a corrective "resolution advisory" (RA) is a "resolution advisory":

• which does not require any action from the pilot but on the contrary asks him not to modify his current vertical speed rate.

• asking the pilot to modify effectively the vertical speed of his aircraft.

• asking the pilot to modify the heading of his aircraft.

An "intruding traffic advisory" is represented on the display system of the TCAS 2 (Traffic Collision Avoidance System) by displaying:

• a red full square.

• a blue or white full lozenge.

• a yellow full circle.

A "resolution advisory" (RA) is represented on the display system of the TCAS 2 (Traffic Collision Avoidance System) by a :

• red full square.

• blue or white full lozenge.

• blue or white empty lozenge.

A "close traffic advisory" is displayed on the display device of the TCAS 2 (Traffic Collision Avoidance System) by:

• an orange full circle.

• a blue or white empty lozenge.

• a blue or white full lozenge

The TCAS II data display devices can be in the form of: 1- a specific dedicated screen 2- a screen combined with the weather radar 3- a variometer represented on a liquid crystal screen which allows the display of Traffic Advisory (TA) and Resolution Advisory (RA) 4- an EFIS (Electronic Flight Instrument System) screen The combination regrouping all the correct statements is:

• 1, 2 and 3.

• 1, 2, 3 and 4.

• 3 and 4
