MATS REFERENCES Flashcards
Altitude Filters - Select altitude filters that include, as a minimum, the following limits:
- The altitudes normally within the jurisdiction of your sector
- The first usable altitude in any vertically adjoining airspace under the jurisdiction of another controller, plus 200 feet beyond that altitude
- If the boundary between vertically adjoined sectors is in RVSM airspace,
2,000 feet plus 200 feet
Publications - Comply with:
- Unit procedures (They may supplement, but not contradict, procedures in this manual.)
- Directives
- Information Bulletins
- Director Approval Letters (DAL)
- Information Circulars (AIC)
- Memorandums
- Agreements
- Arrangements
- Other items, as required
Rules for Accords
The GMFIR or unit manager is responsible to ensure accords are established when it is necessary to:
Set out responsibilities for the provision of air traffic services.
Delegate responsibility for airspace or define conditions for its use.
Detail coordination requirements.
Establish procedures for standard operating practices that supplement the basic requirements as published in MATS or other directives.
Define procedures for other operational reasons offering a benefit to NAV CANADA units or outside parties.
Specialty Operations Manual (SOM)
: usually there is one for each
specialty. Some units have a Unit Operations Manual (UOM) that
pertains to all specialties.
Operations Directive:
It is an amendment to current SOM or UOM. Controllers need to read them and sign, agreeing they have done so; some amendments require a verbal briefing. They expire or are
incorporated into Operations Manuals
Staff Memos:
they are a way to communicate with all staff about events in the workplace. These are non-operational in nature
Do not apply separation between an aircraft and Class F airspace or a Canadian Military Operations Area (MOA) if one of the following applies:
- The aircraft is operating in an ALTRV.
- The pilot states having obtained permission from the user agency to enter the
airspace. - The user agency releases the airspace to the controlling agency[1]
. - The pilot has been cleared for a contact or visual approach.
1 The DAH states the times that Class F airspace is active. A user agency may release an area in part or in total when not in use to a controlling agency. In such cases, ATC may advise the aircraft that the airspace is inactive and issue
a clearance. Such provisions for release should be contained in an agreement between the user and controlling agency. Areas released use assume the same airspace classification as the surrounding airspace.
Class F Flight Hazards. 4 If’s
If you observe, or if responsible agencies, individuals, or other pilots report conditions that may affect flight safety, inform pilots.[1]
If you notice or are aware of a hazard to the safety of aviation, immediately inform your supervisor.
If you observe, or if responsible agencies, individuals, or other pilots relay to you information about aerodrome conditions that may affect flight safety, inform the aerodrome operator.
If information is available, advise pilots when their aircraft has entered, or is about to enter, active Class F airspace[2], airspace restricted by the Minister[3], an MOA, active American special-use airspace, or a TFR.
non-RVSM aircraft in RVSM
If operation in RVSM airspace is authorized for a non-RVSM aircraft, identify the status of the aircraft when passing and receiving a control estimate.
“Negative RVSM”
Forward the following to an IFR unit or sector:
- Revisions to previously passed data
- Control estimate time revisions of 3 minutes or more
This may be passed electronically.
Obtaining Readbacks
When issuing or relaying an IFR clearance or IFR instruction or amendment, obtain an accurate readback unless one of the following applies:
* Information is relayed electronically.
* An arrangement specifies otherwise.
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
You may consider an aircraft identified, when the conditions are met for any of the following methods:
- Transferred or Coordinated Identification
- Appropriate PPS Changes
- Aircraft ID in ADS‑B Data Tag
- Aircraft Position and Movements on Situational Display
Transferred or Coordinated Identification In addition to the methods listed above[1], you may consider the aircraft identified when identification is transferred by handoff[2] or coordinated by point out.
If identification becomes doubtful or is lost, immediately do either of the following:
- Identify or re-identify the aircraft using the same technique more than once or use more than one of the techniques provided in Identification Methods.
- Terminate ATS surveillance service and apply procedural separation.
8 reasons identification may be doubtful
- The position or movements of other A/C
- The observation of more than one A/C responding to an identification instruction
- Temporary loss of the PPS
- Coasting of PPS
- Merging of PPS
- Ambiguous PPS
- Display Clutter
- Other circumstances
Consider identification to be lost if a linked PPS ceases to be displayed after “CST” is displayed in its data tag, unless either of the following applies:
- You are able to maintain identification of an unlinked PPS being displayed for the aircraft.
- The PPS re-links within a sufficiently short period such that, considering the progress of the aircraft, you have no doubt about its identity.
Complete a handoff before the aircraft passes any of the following:
- The sector or unit boundary
- A designated control transfer point
- Any handoff point defined in an
arrangement or agreement
Do an automated handoff, unless either of the following applies:
- You are handing off an unlinked PPS.
- A system malfunction or deficiency makes it unfeasible.
Relay the following to the receiving controller:
- The appropriate flight data and control information, including amendments
- Any information received from the pilot or operator concerning the aircraft’s fuel state or fuel reserves Obtain consent of the receiving controller.
