MATS ACC > Glossary

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

Question 4

Define Linkage

Answer 4

MATS ACC > Glossary

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

Question 5

Define Separation

Answer 5

MATS ACC > Glossary

SEPARATION - The spacing between aircraft, altitudes, or tracks

Question 6

Define Same Track

Answer 6

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 7

Define Transition Speed

Answer 7

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.

Question 8

5 Types of ATS Surveillance Service

Answer 8

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 9

3 Steps of Separation Basics

Answer 9

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

Question 10

“If the type of separation or the minimum used to separate aircraft cannot be maintained…”

Answer 10

MATS ACC > Separation > Separation Basics

If the type of separation or the minimum used to separate aircraft cannot be maintained, take action to ensure that another type of separation exists, or another minimum is established, before the current separation becomes insufficient.

Question 11

“To ensure an expeditious flow of traffic, operate as closely…”

Answer 11

MATS ACC > Separation > Separation Basics

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.
Exceptional circumstances may include, but are not limited to, unlawful interference, adverse meteorological conditions or navigational difficulties.

Question 12

Discrete and Non-Discrete Codes

Answer 12

MATS ACC > ATS Surveillance > SSRs and Aircraft Codes > Code Assignment

Assign an aircraft a discrete code in preference to a non-discrete code.[5]
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
5 Due to system limitations regarding the number of codes, minimize discrete code assignment changes.
Gliders use 1202
VFR 12500 ft and below use 1200
VFR above 12500 ft use 1400
IFR High Level uses 2000
IFR Low Level uses 1000
