Question 1

ATS SURVEILLANCE SERVICE

Answer 1

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

Question 2

ATS SURVEILLANCE SYSTEM

Answer 2

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

ATS SURVEILLANCE CONTROL SERVICE

Answer 3

An air traffic control service provided with information derived from ATS surveillance equipment sources.

Question 4

ATS SURVEILLANCE SEPARATION

Answer 4

Spacing of aircraft in accordance with established minima, based on information derived from ATS surveillance.

Question 5

ATS SURVEILLANCE ADVISORY

Answer 5

Advice and information based on ATS surveillance observations.

Question 6

ATS SURVEILLANCE MONITORING

Answer 6

The use of ATS surveillance for providing aircraft with information and advice relative to significant deviations from their normal flight path.

Question 7

NAVIGATIONAL ASSISTANCE

Answer 7

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

Question 8

DCPC (DIRECT CONTOLLER-PILOT COMMUNICATIONS)

Answer 8

Communication between a controller and a pilot without resort to a relay through another unit.

Question 9

SEPARATION

Answer 9

The spacing between aircraft, altitudes, or tracks.

Question 10

(ALT) ALTITUDE

Answer 10

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 11

CONTROLLED AIRSPACE

Answer 11

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

Question 12

RSE (radar site equipment)

Answer 12

A radar owned and operated by NAV CANADA

Question 13

RADAR

Answer 13

A radio detection that provides information on range, azimuth, or elevation of objects, of two types:

-Primary surveillance radar
-Secondary surveillance radar

Question 14

PSR (PRIMARY SURVEILLANCE RADAR)

Answer 14

A radar system that detects objects by means of reflected radio signals. Also called: primary radar.

Question 15

SSR (SECONDARY SURVEILLANCE RADAR)

Answer 15

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 16

LINKAGE

Answer 16

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

Question 17

ADS-B (AUTOMATIC DEPENDENT SURVEILLANCE - BROADCAST)

Answer 17

A means by which aircraft, aerodrome vehicles, and other objects can automatically transmit and/or receive data as identification, position, and additional data, as appropriate, in a broadcast movie via a data link.

Question 18

PPS (PRESENT POSITION SYMBOL)

Answer 18

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 19

CJS (CONTROLLER JURISDICTION SYMBOL)

Answer 19

Symbol that identifies a sector.

Question 20

READBACK

Answer 20

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 21

FL (FLIGHT LEVEL)

Answer 21

An altitude expressed in hundreds of feet indicated on an altimeter set to 29.92 inches of mercury or 1013.2 hectopascals.

Question 22

AIR TRAFFIC CONTROL CLEARANCE

Answer 22

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 23

AIR TRAFFIC CONTROL INSTRUCTION

Answer 23

A directive issued by an air traffic control unit for air traffic control purposes.

Question 24

NON-ATS SURVEILLANCE ROUTE

Answer 24

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 25

VECTOR

Answer 25

A heading given by a controller to a pilot to provide navigational guidance.

Question 26

HEADING

Answer 26

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 27

TRACK

Answer 27

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 28

INDICATED AIRSPEED

Answer 28

The uncorrected reading on the airspeed indicator.

Question 29

TAS (TRUE AIRSPEED)

Answer 29

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 as “true airspeed” and not shortened to “airspeed”.

Question 30

MACH NUMBER

Answer 30

The ratio of the speed of an object to the local speed of sound.

Question 31

Transition Speed

Answer 31

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.

Question 32

SAME TRACK

Answer 32

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 33

NA

Answer 33

NA

Question 34

Traffic Information

Answer 34

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.
