ADS-B

Question 1

What does ADS-B stand for?

Answer 1

Automatic Dependent Surveillance Broadcast

Question 2

What infrastructure operation is required on all aircraft as of the new rule the FAA mandated in 2014?

Answer 2

ADS-B

Question 3

Class A requires aircraft to use:

Answer 3

1090 ES data link
(18K ft and above)

Question 4

Class B and C can use either:

Answer 4

A Universal Access Transceiver (UAT) or a 1090 ES data link
(Up to 10K ft)

Question 5

Class E is required to use either:

Answer 5

A Universal Access Transceiver (UAT) or a 1090 ES data link
(10K ft to 18K ft)

Question 6

ASD-B enables the widespread use of:

Answer 6

Satellite based GPS technology in aviation

Question 7

Aircraft are required to have equipment that:

Answer 7

Continually broadcasts their position

Question 8

The Mode S transponder replies with a Mode S format that includes what?

Answer 8

The aircraft’s unique discrete 24-bit Mode S address

Question 9

ADS-B relies on three avionics components:

Answer 9

A high-integrity GPS navigation source, a Mode S transponder, and data link (ADS-B unit)

Question 10

There are several types of certified ADS-B data links, but the most common ones operate at:

Answer 10

1090 MHz or 978 MHz

Question 11

The FAA would like to see aircraft that operate below 18K ft to use which link?

Answer 11

978 MHz

Question 12

To obtain ADS-B capability at 1090Mhz you can:

Answer 12

Install a new transponder or modify an existing one

Question 13

What is TIS-B?

Answer 13

A ground based broadcast service that provides secondary surveillance radar (SSR) - derived traffic data

Question 14

Only conventional Mode C and Mode S transponder-equipped targets reporting their barometric altitude will be included in a TIS-B broadcast. What does this mean?

Answer 14

This means most Mode C and Mode S transponders with altitude encoders that are within sight of both nearby radars and Ground Based Transmitters (GBTs) will be shown on the receiving aircraft’s Cockpit Display of Traffic
Information (CDTI).

Question 15

Aircraft that have Mode-A transponders (transponders without altitude reporting capability) and aircraft without transponders will not:

Answer 15

be displayed on the receiving aircraft’s Cockpit Display of Traffic Information (CDTI)

Question 16

To reduce display clutter, the TIS-B service is only providing traffic information below:

Answer 16

18,000 feet

Question 17

Updates of TIS-B traffic will occur less often than ADS-B updates because:

Answer 17

the update rates for SSRs are approximately once every 5 to 12 seconds, compared to the once-per-second update rate available with ADS-B

Question 18

What is FIS-B?

Answer 18

FIS-B is the ground-to-air broadcast

service of aeronautical information once every five to twelve seconds that allows pilots to operate more safely and efficiently. FIS-B products can be textually or graphically depicted.

Question 19

There are two basic aircraft data link configurations that provide ADS-B capabilities:

Answer 19

Transmit-only systems
and
Combined transmit and receive systems

Question 20

For a combined transmit and receive system, three main avionics components are required:

Answer 20

1) 1090 Extended Squitter (1090ES) or UAT data link transceiver
2) A GPS receiver or another suitable position source
3) Display

Question 21

Which systems could only see other aircraft equipped with the same technology?

Answer 21

Traffic Alert and Collision Avoidance System (TCAS)

Question 22

What is a Cockpit Display of Traffic Information (CDTI)?

Answer 22

A stand-alone or integrated display which provides an aircraft crew with detailed information about other aircraft, specifically spacing intervals

Question 23

What is a Primary Surveillance Radar (PSR)?

Answer 23

A ground-based radar system that measures distance and bearing to an aircraft based solely on radar reflection

Question 24

What is a Secondary Surveillance Radar (SSR)?

Answer 24

A ground-based system which makes use of an aircraft’s transponder(s) to relay the following information: a four-digit identification code (Mode A), altitude (Mode C), a unique identifier (Mode S), a flight identification number (Elementary Surveillance)
