MATS 104-A Flashcards
Two Types of Control Service (List and describe)
Procedural Control
Based on time, speed, distance, and the capabilities of aircraft navigation systems
ATS Surveillance Control
Based on distance only.
The use of ATS surveillance will enable you to make more efficient use of your airspace. In ATS surveillance environments, we can see the present positions of airplanes on our situation display; this is not true in procedural environments.
MATS rule regarding surveillance control vs procedural control
Use an ATS surveillance control procedure in preference to a procedural control procedure unless you or the pilot gain an operational advantage.
MATS GLOSSARY
ATS SURVEILLANCE SERVICE
A term used to indicate a service provided directly by means of an ATS surveillance system
MATS 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.
MATS 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.
Our Mandate, As per MATS
is to provide an area, terminal or oceanic control service, as well as other services, to aircraft operating in our airspace. ATS surveillance is the main tool in the control of aircraft in our airspace.
ATS Surveillance can be used to provide other services:
LIST
ATS SURVEILLANCE CONTROL SERVICE
ATS SURVEILLANCE SEPARATION
ATS SURVEILLANCE ADVISORY
ATS SURVEILLANCE MONITORING
Navigational Assistance
ATS SURVEILLANCE CONTROL SERVICE
An air traffic control service provided with information derived from ATS surveillance equipment sources
Example: turning an aircraft 20 degrees to gain separation between it and another aircraft
ATS SURVEILLANCE SEPARATION
Spacing of aircraft in accordance with established minima, based on information derived from ATS surveillance
Example: Maintaining 1000 feet vertical separation between co-located PPSs, until 5 miles between the centres of the PPSs is achieved
ATS SURVEILLANCE ADVISORY
Advice and information based on ATS surveillance observations
Example: giving advice to an aircraft about weather observed on the situation display (if so equipped)
ATS SURVEILLANCE MONITORING
The use of ATS surveillance for providing aircraft with information and advice relative to significant deviations from their normal flight path
Example: You notice an aircraft off course, you query the aircraft, and assist it back on course
MATS
Navigation Assistance
Unless specifically prohibited, use ATS surveillance to provide navigation assistance if a pilot requests it
navigation assistance may be in the form of position information, vectors, or track and ground speed checks
Example: Informing an aircraft of the distance from their destination airport so they can plan an appropriate descent profile
MATS ACC > Service Fundamentals > ATS Surveillance Service
You may apply ATS surveillance control procedures, prodvided:
- 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
o The aircraft has been cleared for an approach
o You have transferred communication to the tower (The arrival controller is responsible for ensuring separation until control is transferred to the tower) - You are satisfied that the displayed ATS surveillance information is adequate
Vectoring into class G Airspace
You may vector an aircraft into class G airspace if you inform the pilot and obtain the pilot’s approval
DCPC
(DIRECT CONTROLLER-PILOT COMMUNICATIONS)
Communication between a controller and a pilot without resort to a relay through another unit
MATS ACC > ATS Surveillance > ATS Surveillance Equipment >
ATS Surveillance Failure or Degradation
If you are not satisfied that the displayed ATS surveillance information is adequate:
- Inform the supervisor or delegated authority
- Base subsequent control actions on direction provided in ATS directives supplemented by direction from your supervisor or delegated authority. If such direction is not available, base your actions on your assessment of the equipment

Issue clearances and instructions as necessary to maintain a safe, orderly, and
expeditious flow of traffic under the control of your unit.
MATS ACC > Service Fundamentals > Control Service
Provide area, terminal, or oceanic control service to:
- IFR aircraft in controlled airspace
- VFR aircraft in Class A and Class B airspace.
(Note: If authorized by the minister of transport, CARs permits VFR operations in class A airspace)
Give priority to providing control service. Provide other services to the fullest possible extent
MATS ACC > Glossary
Separation
The spacing between aircraft, altitudes, or tracks
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
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
MATS ACC > Separation > 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
MATS ACC > Separation > Separation Basics
To ensure an expeditious flow of traffic, operate…..
To ensure an expeditious flow of traffic, operate as closely to the prescribed minimum as circumstances permit. If exceptional circumstances call for extra
caution, apply greater separation than the specified minimum.

MATS ACC > ATS Surveillance > SSRs and Aircraft Codes
If the PPS or data tag for a particular aircraft is not displayed as expected:
- Instruct the pilot to reset the transponder, stating the currently assigned code.
“RESET TRANSPONDER, SQUAWK XXXX” - If resetting the transponder does not resolve the problem, assign a different code.
If an aircraft’s transponder appears to be unserviceable or malfunctioning, inform the pilot and, if appropriate, the adjacent sector or unit. If an aircraft’s transponder is set to standby or turned off, inform the adjacent sector or unit.
MATS ACC > ATS Surveillance > SSRs and Aircraft Codes
Instruct pilots of transponder-equipped aircraft to reply to SSR interrogation by…..
Instruct pilots of transponder-equipped aircraft to reply to SSR interrogation by assigning the appropriate code. If required, you may assign special condition codes.
MATS ACC > ATS Surveillance > SSRs and Aircraft Codes > Code Assignment
Assign an aircraft a discrete code….
Assign an aircraft a discrete code in preference to a non-discrete code.[5]
MATS ACC > ATS Surveillance > SSRs and Aircraft Codes > Code Assignment
You may assign a non‑discrete code to either of the following:
- An aircraft that has canceled or closed its IFR flight plan and is not requesting further ATS surveillance service
- A VFR aircraft for which ATS surveillance service is being terminated
Due to system limitations regarding the number of codes, minimize discrete code assignment changes.
If a discrete code is not assigned by ATC:
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.
MATS 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
MATS GLOSSARY
PSR
What’s the range?
(PRIMARY SURVEILLANCE RADAR) - A radar system that detects objects by means of reflected radio signals. Also called: primary radar
Max range 80nm
MATS GLOSSARY
SSR
What’s the range?
(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
Max range 250 nm
