Block 1 Glossary

Question 1

Define ATS Surveillance Service

Answer 1

MATS ACC > Glossary

ATS SURVEILLANCE SERVICE – A term used to indicate a service provided directly by means of an ATS surveillance system.

Question 2

Define ATS Surveillance System

Answer 2

MATS ACC > Glossary

ATS SURVEILLANCE SYSTEM - A generic term meaning variously, ADS-B, PSR, SSR or any comparable ground-based system that enables the identification of aircraft. A comparable ground-based system is one that has been demonstrated, by comparative assessment or other methodology, to have a level of safety and performance equal to or better than monopulse SSR.

Question 3

Define ATS Surveillance

Answer 3

MATS ACC > Glossary

ATS SURVEILLANCE – All methods of remotely sensing aircraft using certified/commissioned electronic equipment including PSR, SSR, MLAT, ADS-B, without the benefit of visual observation.

Question 4

5 Types of ATS Surveillance Service

Answer 4

MATS ACC > Glossary

■ ATS SURVEILLANCE CONTROL SERVICE – An air traffic control service provided with information derived from ATS surveillance equipment sources
■ ATS SURVEILLANCE SEPARATION – Spacing of aircraft in accordance with established minima, based on information derived from ATS surveillance.
■ ATS SURVEILLANCE ADVISORY – Advice and information based on ATS surveillance observations.
■ ATS SURVEILLANCE MONITORING – The use of ATS surveillance for providing aircraft with information and advice relative to significant deviations from their normal flight path.

NAVIGATIONAL ASSISTANCE – The provision of position information, vectors, or track and ground speed checks.

Question 5

Define DCPC

Answer 5

MATS ACC > Glossary

DCPC (DIRECT CONTROLLER-PILOT COMMUNICATIONS) - Communication between a controller and a pilot without resort to a relay through another unit.

Question 6

Define Separation

Answer 6

MATS ACC > Glossary

SEPARATION - The spacing between aircraft, altitudes, or tracks

Question 7

Define Altitude

Answer 7

MATS ACC > Glossary

(ALT) ALTITUDE - The vertical distance of a level, a point or an object considered as a point, measured from mean sea level. Also called: indicated altitude

Question 8

Define Track

Answer 8

MATS ACC > Glossary

TRACK - The projection on the earth’s surface of the path of an aircraft, the direction of which path at any point is usually expressed in degrees from true, magnetic, or grid north

Question 9

Define Controlled Airspace

Answer 9

MATS ACC > Glossary

CONTROLLED AIRSPACE - An airspace of defined dimensions within which ATC service is provided.

Question 10

Define RSE

Answer 10

MATS ACC > Glossary

RSE (radar site equipment) – A radar owned and operated by NAV CANADA

Question 11

Define Radar

Answer 11

MATS ACC > Glossary

RADAR - A radio detection device that provides information on range, azimuth, or elevation of objects, of two types:
* Primary surveillance radar
* Secondary surveillance radar

Question 12

Define PSR

Answer 12

MATS ACC > Glossary

PSR (PRIMARY SURVEILLANCE RADAR) - A radar system that detects objects by means of reflected radio signals. Also called: primary radar

Question 13

Define SSR

Answer 13

MATS ACC > Glossary

SSR (SECONDARY SURVEILLANCE RADAR) – A radar system that requires complementary aircraft equipment (transponder). The transponder generates a coded reply signal in response to transmissions from the ground station (interrogator). Since this system relies on transponder-generated signals rather than signals reflected from the aircraft, as in primary surveillance radar, it offers significant operational advantages such as increased range and positive identification. Also called: secondary radar

Question 14

Define Linkage

Answer 14

MATS ACC > Glossary

LINKAGE - An automated or manual function that matches ATS surveillance data with flight plan data.

Question 15

Define ADS-B

Answer 15

MATS ACC > Glossary

ADS-B (AUTOMATIC DEPENDENT SURVEILLANCE - BROADCAST)- A means by which aircraft, aerodrome vehicles, and other objects can automatically transmit and/or receive data such as identification, position, and additional data, as appropriate, in a broadcast mode via a data link.

Question 16

Define PPS

Answer 16

MATS ACC > Glossary

PPS (PRESENT POSITION SYMBOL) - The visual indication, in symbolic form, on a situation display, of the position of an aircraft, aerodrome vehicle, or other object obtained after automatic processing of positional data.

Question 17

Define CJS

Answer 17

MATS ACC > Glossary

CJS (CONTROLLER JURISDICTION SYMBOL) - Symbol that identifies a sector.

Question 18

Define Readback

Answer 18

MATS ACC > Glossary

READBACK - A procedure whereby the receiving station repeats a received message or an appropriate part thereof to the transmitting station so as to obtain confirmation that the message was received correctly.

Question 19

Define Flight Level

Answer 19

MATS ACC > Glossary

FL (FLIGHT LEVEL) - An altitude expressed in hundreds of feet indicated on an altimeter set to 29.92 inches of mercury or 1013.2 hectopascals.

Question 20

Define Clearance

Answer 20

MATS ACC > Glossary

AIR TRAFFIC CONTROL CLEARANCE - An authorization issued by an ATC unit for an aircraft to proceed within controlled airspace in accordance with the conditions specified by that unit.
Also called:
* Air traffic clearance
* ATC clearance
* Clearance

Question 21

Define Instruction

Answer 21

MATS ACC > Glossary

AIR TRAFFIC CONTROL INSTRUCTION - A directive issued by an air traffic control unit for air traffic control purposes.

Question 22

Define IAS

Answer 22

MATS ACC > Glossary

INDICATED AIRSPEED - The uncorrected reading on the airspeed indicator.

Question 23

Define TAS

Answer 23

MATS ACC > Glossary

TAS (TRUE AIRSPEED) - The airspeed of an aircraft relative to undisturbed air. It is used primarily in flight planning and the enroute portion of flight. When used in pilot/controller communications, it is referred to as “true airspeed” and not shortened to “airspeed.”

Question 24

Define Mach Number

Answer 24

MATS ACC > Glossary

MACH NUMBER - The ratio of the speed of an object to the local speed of sound.

Question 25

Define Same Track

Answer 25

MATS ACC > Glossary

SAME TRACK - In the application of separation, expression used by ATC to indicate identical tracks or tracks that converge or diverge at an angle of 1° to 44° inclusive.

Question 26

Define Non-ATS Surveillance Route

Answer 26

MATS ACC > Glossary

NON-ATS SURVEILLANCE ROUTE - A route on which an aircraft can determine its position, track, and, consequently, the minimum IFR altitude without the benefit of ATS surveillance information

Question 27

Define Vector

Answer 27

MATS ACC > Glossary

VECTOR - A heading given by a controller to a pilot to provide navigational guidance

Question 28

Define Heading

Answer 28

MATS ACC > Glossary

HEADING - The direction in which the longitudinal axis of an aircraft is pointed, usually expressed in degrees from north (true, magnetic, compass, or grid north).

Question 29

Define Traffic Information

Answer 29

MATS ACC > Glossary

TRAFFIC INFORMATION - Information issued by ATS to pilots regarding other known or observed traffic that may be in such proximity to their position or intended route as to warrant their attention.

Question 30

Define Transition Speed

Answer 30

Transition speed is the speed at which a pilot makes the transition between indicated airspeed and Mach number when climbing or from Mach number to indicated airspeed when descending.
