When an aircraft is at an established minimum vectoring altitude that does not provide adequate clearance above a prominent obstruction, vector the aircraft by one of the following minima:
* 5 miles, if the position of the obstruction is indicated on CSiT or NARDS
* 3 miles, if the following apply:
◦ You provide terminal control service.
◦ The ATS surveillance sources include MLAT/WAM, DND-NG, or RSE but do not include DND-NWS.
◦ CSiT or NARDS displays a maximum range of 120 miles from left to right.
◦ The obstruction is enclosed within a circular buffer that is indicated on CSiT or NARDS. (Vectoring an Aircraft Past an Obstruction)
The buffer must be displayed at the required TS surveillance separation distance from the obstruction.

Indicated Airspeed (IAS)
Terminav
The uncorrected reading on the airspeed indicator.
True Aispeed (TAS)
MATS ACC > Glossary
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.”
Ground Speed (GS)
is the speed of the aircraft over the surface of the earth.
Mach Number
MATS ACC > Glossary
The ratio of the speed of an object to the local speed of sound.
KNOTS to NM/min
Consequently, using multiples of 60 we can conclude:
60 mph = 1 mile per minute
120 mph = 2 miles per minute
180 mph = 3 miles per minute
240 mph = 4 miles per minute
If required to achieve or maintain required spacing or to minimize…
Speed Assignments
MATS ACC > ATS Surveillance > Speed Assignments
If required to achieve or maintain required spacing or to minimize vectoring, instruct a pilot to adjust the aircraft’s speed.
Avoid repetitive and constant speed changes unless they are required because of traffic flow, traffic levels, pilot workload, or airspace design.
Express the speed adjustment using either of the following methods:
Expression of Speed Adjustments
MATS ACC > ATS Surveillance > Speed Assignments > Expression of Speed Adjustments
Express the speed adjustment using either of the following methods:
* As a multiple of 10 knots, based on IAS

There are two ways a controller can determine the current altitude of an aircraft:
i. Ask the pilot for their current altitude.
ii. Look at the aircraft’s data tag on the situation display.
Separate aircraft consistently according to these…
Separation Basics
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
If the type of separation or the minimum used to separate aircraft…
Separation Basics
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.
For example, if two aircraft are on converging tracks, ensure that vertical or longitudinal separation exists before lateral separation is lost.”
To ensure an expeditious flow of traffic,…
Separation Basics
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.[1]
Exceptional cicumstances may include but are not limited to, unlawful interference, adverse meteorological conditions or navigational difficulties.
How do you express different types of speed?
Speed Phraseology
MATS ACC > Appendix: Communication > Communication Fundamentals > Values and Units > Speed
Express speed using separate digits either in knots or with the Mach number.
Mach Number
TC AIM RAC 11.1 Adherence to Mach Number
Within CDA, aircraft shall adhere to the Mach number assigned by ATC, to within 0.01 Mach, unless approval is obtained from ATC to make a change or until the pilot receives the initial descent clearance approaching destination. If it is necessary to make an immediate temporary change in the Mach number (e.g. because of turbulence), ATC shall be notified as soon as possible that such a change has been made.
If it is not possible to maintain the last assigned Mach number during en route climbs and descents because of aircraft performance, pilots shall advise ATC at the time of the climb/descent request.
How do you ask a pilot what speed they can maintain?
Guidelines for Speed Adjustments
MATS ACC > ATS Surveillance > Speed Assignments> Guidelines for Speed Adjustments
When making speed adjustments, use the guidelines provided in the table below.
What are the maximum IAS for…?
Guidelines for Speed Adjustments
MATS ACC > ATS Surveillance > Speed Assignments> Guidelines for Speed Adjustments
When making speed adjustments, use the guidelines provided in the table below. You may assign speeds that are lower than those specified only after coordinating with the pilot.
If you initiate vectoring, inform the pilot of the following:[4]
Vectoring Initiation
MATS ACC > ATS Surveillance > Vectoring > Vectoring Initiation
If you initiate vectoring, inform the pilot of the following:
* The purpose of vectors and/or the point to which the aircraft is being vectored
* That the aircraft’s SID or STAR is cancelled, if applicable
Do not approve a speed over…
Airspeed Limitations
MATS ACC > ATS Surveillance > Speed Assignments > Airspeed Limitations
Do not approve a speed over 250 knots IAS below 10000 feet above sea level, but acknowledge a pilot who informs you of a requirement to operate above the CARs-regulated speed limitations for minimum safe speed requirements.
If a pilot reports or operates at a speed over 250 knots below 10000 feet above sea level and does not state that it is for minimum safe speed, inform the operations duty manager.
Inform the pilot if you observe any of the following:
Observed Deviations
MATS ACC > ATS Surveillance > Position Information > Observed Deviations
Inform the pilot if you observe any of the following:[3]
* It appears that the aircraft will deviate or has deviated from its assigned route or holding area.
* The altitude readout indicates that the aircraft has deviated by 300 feet or more from its assigned altitude.
* The altitude readout indicates that the aircraft has deviated by 200 feet from its assigned altitude and the VMI indicates that the aircraft is continuing its climb or descent away from the assigned altitude.
When an aircraft has deviated from assigned airspace, if necessary, assist it in returning to the assigned airspace.
Give priority to an aircraft…
Flight Priority > Assigning Altitudes
MATS ACC > Service Fundamentals > Control Service > Flight Priority > Assigning Altitudes
Give priority to an aircraft carrying a sick or seriously injured person, whose condition requires priority.
When one or more pilots request the same altitude, give priority to the aircraft already at the altitude.
When two or more aircraft are at the same altitude, give priority to the leading aircraft.
You may adjust the altitude assignment for either of the following reasons:
* To accommodate the maximum number of aircraft at their requested altitudes
* To comply with ATFM requirements
What is transition Speed?
Transition Speed
