Glossary Terms Flashcards
ATS Surveillance Service
Broad statement
A term used to indicate a service provided directly by means of an ATS surveillance system.
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.
ATS SURVEILLANCE CONTROL SERVICE
Broad statement
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.
You may apply ATS surveillance control procedures, provided:
- The aircraft is identified.
- The aircraft is in controlled airspace, except as described in Vectoring into Class G Airspace.
- You are in direct communication with the pilot, unless:
◦ The aircraft has been cleared for an approach.
◦ You have transferred communication to the tower. - You are satisfied that the displayed ATS surveillance information is adequate.
DCPC
Communication between a controller and a pilot without resort to a relay through another unit.
Control Service
Issue clearances and instructions as necessary to maintain a safe, orderly, and expeditious flow of traffic under the control of your unit.
SEPARATION
The spacing between aircraft, altitudes, or tracks
(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
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
CONTROLLED AIRSPACE
- An airspace of defined dimensions within which ATC service is provided.
RSE (radar site equipment)
A radar owned and operated by NAV CANADA
RADAR
A radio detection device that provides information on range, azimuth, or elevation of objects, of two types: * Primary surveillance radar * Secondary surveillance radar
PSR (PRIMARY SURVEILLANCE RADAR)
A radar system that detects objects by means of reflected radio signals. Also called: primary radar
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).
LINKAGE
An automated or manual function that matches ATS surveillance data with flight plan data.
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.
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
CJS (CONTROLLER JURISDICTION SYMBOL)
Symbol that identifies a sector.
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.
(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
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.
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.
AIR TRAFFIC CONTROL INSTRUCTION
A directive issued by an air traffic control unit for air traffic control purposes.
IFR Clearance Format
Issue clearance items, as appropriate, in the following order:
1. Prefix/aircraft ID
2. Clearance limit
3. SID
4. Route
5. Altitude
6. Speed
7. Departure, enroute, approach, or holding instructions
8. Special instructions or information, may include an SSR code
9. Traffic information
Functional Goal #1
In the provision of air traffic control and flight information service, all Air Traffic Services units must provide:
* Uniform application of approved standards and procedures
* Professional communications
* Full–time attentive flight monitoring and flight information services
INDICATED AIRSPEED
The uncorrected reading on the airspeed indicator
TAS (TRUE AIRSPEED)
The airspeed of an aircraft relative to undisturbed air.
MACH NUMBER
The ratio of the speed of an object to the local speed of sound.
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.
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
VECTOR
A heading given by a controller to a pilot to provide navigational guidance
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).
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.
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.
Separation Basics
Separate aircraft consistently according to these fundamentals of safe, orderly, and expeditious control:
- Planning: determine the appropriate separation minimum required
- Executing: implement the selected standard
- Monitoring: ensure that the planned and executed separation is maintained
