Answer 8

E-TCAS 

Question 9

There are 8 functions of the TCAS, this one detects presence, determines initial range, relative bearing, relative altitude

Answer 9

Surveillance function

Question 10

Display volume has 3 displays-

Above, normal, below

What do each mean?

Answer 10

Above- small volume below, larger above
Normal- centered on own aircraft
Below- large volume below, small volume above

Question 11

This function tracks up to 45 aircraft but only displays 30 that have the highest threat potential

Answer 11

Tracking function

Question 12

This function is based on intruder range divided by range rate

Answer 12

Threat potential evaluation function

Question 13

This function determines appropriate vertical maneuver

Azimuth maneuvers are not generated

Answer 13

Collision avoidance computation function

Question 14

This function has a minimum safe distance that alerts you at 35 seconds

Answer 14

Resolution advisory

Question 15

This function depicts position and threat potential

48 seconds 

Answer 15

Traffic advisory

Question 16

This function coordinates movement via the Mode S transponder

Answer 16

Air to air coordination function

Question 17

This function uses synthesized audio announcements

Answer 17

Aural Alert Function

Question 18

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

Answer 18

NORM 

Question 19

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

Answer 19

EXT RANGE

Question 20

The rate at which the altitude is increasing or decreasing

Answer 20

Vertical speed

Question 21

This is how fast intruder is closing in on your position

Answer 21

Closure rate 

Question 22

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

Answer 22

Intruder altitude

Question 23

What are the two indicators for TCAS

Answer 23

VSI & MFD

VERTICAL SPEED INDICATOR
MULTIFUNCTION DISPLAY

Question 24

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

Answer 24

Traffic advisory

Question 25

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

Answer 25

Resolution advisory

Question 26

What are the components of the TCAS?

Answer 26

``` Processor Directional antenna Antenna cabling TCAS/VSI MFD ```

Question 27

This controls all surveillance, data acquisition. | Transmits 1030 MHz, receives 1090 MHz

Answer 27

 E-TCAS processor

Question 28

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

Answer 28

Directional antenna

Question 29

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

Answer 29

Antenna cabling

Question 30

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

Answer 30

Cables

Question 31

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

Answer 31

VSI

Question 32

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

Answer 32

MFD

Question 33

This is used to control and monitor various functions
