Question 6

GLOSSARY - RNPC

Answer 6

Required Navigation Performance Capability

Question 7

MATS ACC > Service Fundamentals > ATS Surveillance Service

Answer 7

Use an ARS surveillance control procedure in preference to a procedural control procedure unless you or the pilot gain an operational advantage.

Question 8

MATS ACC > Separation > Separation Basics
Separate aircraft consistently according to these fundamentals of safe, orderly, and expeditious control:

Answer 8

• Planning: determine the appropriate separation minimum required
• Executing: implement the selected standard
• Monitoring: ensure that the planned and executed separation is maintained

Question 9

MATS ACC > Separation > Separation Basics

Answer 9

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 10

MATS ACC > Separation > Separation Basics

Answer 10

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.

Question 11

GLOSSARY - RNAV (AREA NAVIGATION)

Answer 11

A method of navigation that permits aircraft operation on any desired flight path within the coverage of ground- or space-based NAVAIDs or within the limits of the capability of self-contained aids, or a combination of these.

Question 12

MATS ACC > Separation > Separation Basics > Control Estimates

Answer 12

Base control decisions on ATC estimates and aircraft performance. Verify the estimate and aircraft performance using position reports over fixes, or as determined by radio aids, ATS surveillance, RNAV, or visual means that accurately define the position of the aircraft.

Question 13

MATS ACC > Separation > Separation Basics > Control Estimates
Use aircraft estimates to verify ATC estimates. If a discrepancy exists between an aircraft estimate and an ATC estimate for the same reporting point, and separation could be affected:

Answer 13

1. Check the accuracy of the ATC estimate.
2. If a discrepancy remains, request the pilot to check the aircraft estimate.
3. If a discrepancy still exists, take appropriate action to ensure that separation is not compromised.

Question 14

MATS ACC > Separation > Separation Basics > Control Estimates

Answer 14

When separating aircraft, the estimated time may not be correct. If an expected report does not arrive and flight safety is likely to be jeopardized, obtain the report no more than 5 minutes after the estimated time over a reporting point. Otherwise, obtain the report as soon as feasible

Question 15

MATS ACC > Separation > Longitudinal Separation

Answer 15

Separate aircraft longitudinally:
* By a minimum expressed in time or distance
* So that the spacing between the estimated positions of the aircraft is never less than a prescribed minimum

Example

If a slower leading aircraft is estimated at a fix 10 minutes ahead of a faster
trailing aircraft, establish vertical separation before or at the time the leading aircraft is estimated at the fix.

Question 16

MATS ACC > Separation > Longitudinal Separation > Time-Based
Longitudinal Separation

Answer 16

Longitudinal Separation
Establish time-based longitudinal separation using one of the following methods:
* By clearing an aircraft to depart at a specified time
* By clearing an aircraft to cross a specified fix at a specified time
* By clearing an aircraft to hold at a fix until a specified time
* By clearing an aircraft to reverse heading
* On the basis of position reports, provided that one of the following applies:
◦ Both aircraft have reported over the same reporting point.
◦ The trailing aircraft has confirmed not yet reaching the reporting point
used by the leading aircraft.

Question 17

MATS ACC > Separation > RNPC Separation > Longitudinal RNPC
Separation > Time-Based RNPC Longitudinal Separation

Answer 17

When applying time-based longitudinal separation, separate RNPC-certified
aircraft on same or crossing tracks by a minimum of 10 minutes.

Question 18

MATS ACC > Separation > RNPC Separation > Longitudinal RNPC
Separation > Distance-Based RNPC Longitudinal Separation

Answer 18

When applying distance-based longitudinal separation, separate RNPC-certified
aircraft on the same track or crossing tracks by a minimum of 30 miles, and:
* Maintain direct communication using VHF/UHF voice.
* Using RNAV or ATS surveillance from a common point, determine distance
and ensure that the required separation is maintained or increased.

Determining Distance
Distance can be determined by requesting RNAV position reports or by using SiT distance measuring tools. Aircraft using RNAV can report a position at
any point along their track.

When applying DME separation, advise RNPC‑certified aircraft to use DME
distance.

Question 19

MATS ACC > Glossary - WAYPOINT

Answer 19

WAYPOINT - A specified geographical location, defined by longitude and latitude, that is used in the definition of routes and terminal segments and for progress-reporting purposes.

Question 20

MATS ACC > Separation > ATS Surveillance Separation

Answer 20

CSiT and NARDS are both operationally certified ATS surveillance display systems that can be used to apply the appropriate separation minima provided in this section. CSiT is the primary display, and NARDS is the auxiliary.

Ensure both aircraft are identified, and that you are in direct communication
using VHF/UHF voice with at least one of them. Do not permit PPSs to touch.

Unless applying target resolution, apply ATS surveillance separation between the centres of PPSs as indicated in ATS Surveillance Separation Conditions. When
providing ATS surveillance control service, a wake turbulence separation standard is required.[1]

Range Bearing Line and Halo Function

The Range Bearing Line (RBL) and Halo function can be used to assist in
determining the separation between PPSs. The distances provided by RBL are measured from centre to centre of the PPSs. The radius of the halo is user-selectable and does not vary with range.

IFR Departures Before Arrivals

When separating a departing aircraft from an arriving aircraft, the minima
indicated in IFR Departures Before Arrivals: Same Runway, IFR Departures
Before Arrivals: Intersecting Runways, and IFR Departures Before Arrivals:
Interacting Runways can supersede those in ATS Surveillance Separation
Conditions

Question 21

MATS ACC > ATS Surveillance > Vectoring > Vectoring
Termination

Answer 21

You may terminate vectoring of an aircraft, provided any of the following apply to
the aircraft:
* It is cleared for an approach.
* It is cleared to hold.
* It is established on a cleared route without requiring navigation assistance.

Inform the pilot of:
* Termination of vectoring, except when the aircraft has been cleared for an approach
* Position of the aircraft when vectoring is terminated, unless you know the pilot has the information.
When an aircraft has been vectored off its cleared route, clear the aircraft to the next waypoint or fix on its route of flight, or vector the aircraft back to a point on its original route.

Question 22

MATS ACC > ATS Surveillance > Position Information

Answer 22

Describe the position of an aircraft in relation to a fix, airway, course, or radial indicated on the situation display
… (Over/passing) (FIX)
… (Number) MILES (direction) of (fix)
… (NAVAID name) (specified) RADIAL IS (number) MILES TO YOUR (LEFT/RIGHT)
… (INTERCEPTING/CROSSING) (NAVAID name) (specified) RADIAL.
… (CROSSING/JOINING/DEPARTING/LEAVING) (airway)

Question 23

MATS ACC > ATS Surveillance > Vectoring > Vectoring for the
Approach > Vectoring to Intercept the Final Approach Course

Answer 23

Vector an aircraft to intercept the final approach course at an angle of 30° or less, and one of the following distances:
* 2 miles or more from the point at which final descent will begin

Question 24

MATS ACC > ATS Surveillance > Vectoring > Vectoring
Termination

Answer 24

When an aircraft has been vectored off its cleared route, clear the aircraft to the next waypoint or fix on its route of flight, or vector the aircraft back to a point on its original route.

Question 25

MATS ACC > Separation > Separation from Special-Use Airspace

Answer 25

Within controlled airspace, you may have to apply separation between aircraft and the outer edge of the following airspaces:
* Canadian Class F Airspace
* Canadian Airspace Restricted by the Minister
* American Special-Use Airspace and Temporary Flight Restriction (TFR)

Question 26

MATS ACC > Separation > Separation from Special-Use Airspace >
Canadian Class F Airspace > Class F Restricted Airspace (CYR) >
Lateral Separation with a CYR

Answer 26

If not using ATS surveillance, ensure the protected airspace for the IFR or CVFR
aircraft does not overlap the CYR.
If using ATS surveillance, ensure direct communication using VHF/UHF voice,
refer to the table below.
Flight Rules: IFR or CVFR - Does not include DND-NWS - You provide terminal control service. The ATS surveillance sources include MLAT/WAM, DND-NG, Or RSE.
CSIT or NARDS display a maximum range of 120 miles form left to right.
An altitude readout is displayed for the aircraft, or the aircraft is at or below 15000 feet ASL. - 3 miles

Is or includes DND-NWS - 10 miles

Question 27

MATS ACC > Separation > ATS Surveillance Separation > ATS
Surveillance Separation From a Procedural Boundary

Answer 27

If an aircraft is identified and receiving ATS surveillance service, separate that aircraft from the boundary of procedural airspace as indicated in ATS Surveillance Separation between Aircraft and Adjoining Procedural Airspace.

ATS Surveillance Source
Is or includes DND-NWS - 10 MILES SEPERATION
Includes MLAT/WAM,DND-NG, OR RSE but does not include DND-NWS - The following apply:
- you provide terminal control service
- CSIT or NARDS displays a maximum range of 120 miles from left to right
- An altitude readout is displayed for the aircraft, or the aircraft is at or below 15000 feet ASL - 3 MILES
All other situations - 5 miles
