Define ATS Surveillance Service
MATS ACC > Glossary
ATS SURVEILLANCE SERVICE – A term used to indicate a service provided directly by means of an ATS surveillance system.
Define ATS Surveillance System
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.
Define ATS Surveillance
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.
5 Types of ATS Surveillance Service
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.
Define DCPC
MATS ACC > Glossary
DCPC (DIRECT CONTROLLER-PILOT COMMUNICATIONS) - Communication between a controller and a pilot without resort to a relay through another unit.
Define Separation
MATS ACC > Glossary
SEPARATION - The spacing between aircraft, altitudes, or tracks
Define Altitude
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
Define Track
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
Define Controlled Airspace
MATS ACC > Glossary
CONTROLLED AIRSPACE - An airspace of defined dimensions within which ATC service is provided.
Define RSE
MATS ACC > Glossary
RSE (radar site equipment) – A radar owned and operated by NAV CANADA
Define Radar
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
Define PSR
MATS ACC > Glossary
PSR (PRIMARY SURVEILLANCE RADAR) - A radar system that detects objects by means of reflected radio signals. Also called: primary radar
Define SSR
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
Define Linkage
MATS ACC > Glossary
LINKAGE - An automated or manual function that matches ATS surveillance data with flight plan data.
Define ADS-B
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.
Define PPS
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.
Define CJS
MATS ACC > Glossary
CJS (CONTROLLER JURISDICTION SYMBOL) - Symbol that identifies a sector.
Define Readback
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.
Define Flight Level
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.
Define Clearance
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
Define Instruction
MATS ACC > Glossary
AIR TRAFFIC CONTROL INSTRUCTION - A directive issued by an air traffic control unit for air traffic control purposes.
Define IAS
MATS ACC > Glossary
INDICATED AIRSPEED - The uncorrected reading on the airspeed indicator.
Define TAS
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.”
Define Mach Number
MATS ACC > Glossary
MACH NUMBER - The ratio of the speed of an object to the local speed of sound.
