SYS 5 PART3 ATA34 (75-175)

An R.M.I in VOR mode, its pointer is showing a course of 000. If the course knob is adjusted to 010 what happens to the pointer?

• Moves left then hard right.

• Move left.

• Move right.

Track mode of an Radio Altimeter is operational.

• above 10,000 feet.

• from 1.0 to 100 feet.

• from 0 to 2,500 feet.

A decision height window (DH) displays:

• the radar altitude

• The pressure altitude

• The height from sea level

How many aerials are there in a T.C.A.S system?

• 1.

• 2.

• 3.

Differential G.P.S requires.

• 4 satellites and 2 ground based transmitters.

• 3 satellites and two ground based transmitters.

• 4 satellites and 1 ground based transmitter.

The TCAS (Traffic Collision Avoidance System) is a proximity alarm system which detects a 'traffic' when the conflicting traffic is equipped with a:

• SELCAL system

• serviceable weather radar

• serviceable SSR transponder

The TCAS 1 (Traffic Collision Avoidance System) provides : 1- traffic information 2- horizontal resolution (RA: Resolution Advisory) 3- vertical resolution (RA: Resolution Advisory) 4- ground proximity warning The combination regrouping all the correct statements is:

• 1

• 1, 2, 3

• 1, 2, 3, 4

The use of the TCAS (Traffic Collision Avoidance System) for avoiding an aircraft in flight is now general. TCAS uses for its operation:

• the echos of collision avoidance radar system especially installed on board

• the echos from the ground air traffic control radar system

• the replies from the transponders of other aircraft

Concerning the TCAS (Traffic Collision Avoidance System):

• In one of the system modes, the warning: 'TOO LOW TERRAIN' is generated

• No protection is available against aircraft not equipped with a serviceable SSR transponder

• In one of the system modes, the warning: 'PULL UP' is generated

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

• in horizontal and vertical planes

• only in the horizontal plane

• only in the vertical plane
