16
Q

This function coordinates movement via the Mode S transponder

A

Air to air coordination function

17
Q

This function uses synthesized audio announcements

A

Aural Alert Function

18
Q

This mode monitors +/- 8,700ft in vertical plane. Up to 30NM forward, 15NM from the aft, and 20NM to the sides 

A

NORM 

19
Q

This mode monitors +/- 12,700ft in vertical plane (-4000ft below) and has up to 40NM in all directions

A

EXT RANGE

20
Q

The rate at which the altitude is increasing or decreasing

A

Vertical speed

21
Q

This is how fast intruder is closing in on your position

A

Closure rate 

22
Q

This is determined by comparing your barometric altitude to the barometric altitude reported by the intruders transponders mode-C or mode-S reply

A

Intruder altitude

23
Q

What are the two indicators for TCAS

A

VSI & MFD

VERTICAL SPEED INDICATOR
MULTIFUNCTION DISPLAY

24
Q

This is a yellow circle that shows an intruder is nearby within 48 seconds

A

Traffic advisory

25
Q

This is a red square which means a nearby threat is within 35 seconds

A

Resolution advisory

26
Q

What are the components of the TCAS?

A 
Processor
Directional antenna
Antenna cabling
TCAS/VSI
MFD
27
Q

This controls all surveillance, data acquisition.

Transmits 1030 MHz, receives 1090 MHz

A

 E-TCAS processor

28
Q

This is divided into four quadrants and can be found on top of the aircraft and on bottom

A

Directional antenna

29
Q

There are a set of four of these which connects the antennas to the TCAS processor

A

Antenna cabling

30
Q

These are not repairable and will need to be purchased if damaged

A

Cables

31
Q

This provides the pilot and copilot with a constant Visual display of vertical speed, E-TCAS traffic, resolution advisories

A

VSI

32
Q

This indicator is used to enable the pilot or copilot MFD control command of center

Pilots control overrides copilots control

A

MFD

33
Q

This is used to control and monitor various functions

A
