Q

OBTAINING OVERDUE POSITION REPORTS

There will be occasions when aircraft will not make IFR position reports on time because:

A
  • The pilot is still on the previous unit’s frequency.
  • The pilot has changed to or received a wrong frequency (another reason why it is so important to change an aircraft to the appropriate frequency).
  • The pilot forgot to make the position report.
  • The aircraft is late due to non-anticipated wind conditions.
  • The pilot is having in-flight problems and is correcting them.
  • The aircraft has radio problems or communication failure.

  • Airways (including additional airspace for change of direction for high-level airways)
  • Off-airway tracks (including additional airspace for change of direction)
  • Initial, intermediate, final, missed approach, and departure areas
25

NO
26
MATS ACC > Separation > Lateral Separation > Airspace to Protect For converging aircraft, ensure that the protected airspaces do not overlap by doing the following:
* To determine the holding point or the point to effect a restriction, add a DME/GNSS distance from Restriction to be Added to the track overlap indicated in Track Overlap. * Issue one of the following: ◦ A holding instruction (Protecting Airspaces for Converging Aircraft) ◦ A restriction to establish vertical separation (DME/GNSS Restriction for Converging Aircraft) If alternate instructions are not issued, the restriction point must include additional distance to enable the aircraft to enter a hold without an overlap of protected airspace.
27
MATS ACC > Traffic Management > Clearances and Instructions > Issuing and Relaying > Correcting a Clearance or Instruction Identify and correct any errors made during delivery or readback of a clearance or instruction, even if a readback is not required. If there is any possibility of misunderstanding…
... cancel and restate the clearance or instruction in full.
28
MATS ACC > Emergencies and Urgent Operations > Fundamentals (Excerpt) If an aircraft is in an emergency phase as described in Emergency Phases, inform the operations duty manager and other appropriate agencies. Uncertainty Phase No communication received from the earlier of either of the following times:
- Within 30 minutes after communication should have been received from the aircraft. - When an unsuccessful attempt to establish communication with such aircraft was first made
29
For a VOR, we protect...
4 NM either side of the airway centreline to a distance of 51 NM from the VOR, then within lines that diverge at 4.5 degrees from the VOR until they meet the similar lines from the adjacent NAVAID.

SOM 650 AIRWAY OVERLAP B. It has been determined by Airspace Planners that the overlap of protected airspace between V306/V6 discontinues ______ (or ______ including slant range for altitudes below _____ )northwest side of YAR. Aircraft that report more than ________ side of YAR established on either airway are clear.
12.4 miles 13 DME 18000’ ASL 12.4 miles or 13 DME NW
31
TC AIM RAC 9.4 > Descent Out of Controlled Airspace ATC may not clear an aircraft to operate below the MEA of an airway, nor below the minimum IFR altitude in other controlled low level airspace. The pilot, however, may operate at the MOCA, and ATC will approve flight at the MOCA at the pilot’s request. If unable to cancel IFR at the MEA, the pilot may advise that he/she intends to descend to the MOCA. By prior arrangement with ATC, the MEA will be protected in the event that the pilot does not encounter visual conditions at the MOCA. Under this arrangement, the MEA will be protected:
- until the pilot files an arrival report; - for 30 min; to allow descent to the MOCA and return to the MEA when communication is restored with ATC; - if ATC does not hear from the pilot under (a) or (b), until the aircraft is estimated to have arrived at the filed alternate plus 30 min.
32
MATS ACC > Emergencies and Urgent Operations > Fundamentals > Providing Alerting Services (Excerpt) Provide alerting service to:

33
MATS ACC > Flight Plans and Itineraries > Closing Flight Plans and Flight Itineraries > IFR Flight Plan or Flight Itinerary When the pilot of an IFR aircraft closes the IFR flight plan:
* If VFR flight is not permitted due to airspace classification or weather conditions: ◦ Inform the pilot. ◦ If appropriate, pass the most recent weather sequence. ◦ Ask the pilot’s intentions. * Acknowledge the closure and inform the pilot that alerting service is terminated. * Inform the appropriate ACC or the agency responsible for alerting service at the destination.
34
MATS ACC > Traffic Management > Clearances and Instructions > Cancelling IFR If the pilot of an IFR or CVFR aircraft cancels IFR:
* If VFR flight is not permitted due to airspace classification or weather conditions: ◦ Inform the pilot. ◦ If appropriate, pass the most recent weather sequence. ◦ Ask intentions. * Acknowledge the cancellation. - A pilot’s decision to cancel an IFR flight plan or itinerary, or change to a VFR flight plan or itinerary, is not subject to ATC approval * Ask whether the pilot is closing the IFR flight plan or itinerary, and respond as indicated below.
35
MATS ACC > Emergencies and Urgent Operations > Communication Search > Communication Search Steps To conduct a communication search:
1. Contact all communication stations located within or adjacent to the search area that have interphone, facsimile, or radio facilities 2. As appropriate, contact agencies within or adjacent to the search area that have interphone, facsimile, or radio facilities: ◦ Air carriers ◦ Non-scheduled operators ◦ Amateur radio operators ◦ Federal and provincial agencies such as TC, DND, RCMP, Forestry Services, or provincial police 3. As appropriate, contact the following agencies of each major city or town within the search area: ◦ Police ◦ Municipal office ◦ Territorial or Chief telephone operators
36
MATS ACC > Emergencies and Urgent Operations > Communication Search The ACC initiates a communication search and informs JRCC if any of the following occurs:
* No communication has been received from a pilot within 30 minutes of the time a communication should have been received, or from the time an unsuccessful attempt to establish communication with such aircraft was first made, whichever is earlier. * An IFR flight plan has been submitted to depart from a location with no operating control tower or FSS/MFAU, and a departure message or other communication is not received within 60 minutes of the proposed or revised departure time indicated in the flight plan. * An IFR or CVFR aircraft enters the uncertainty phase.
37
MATS ACC > ATS surveillance > Vectoring > Vectoring into Class G Airspace You may vector an aircraft into Class G airspace if...

38
STANDARD HOLD
A standard hold involves an aircraft arriving at the holding fix, followed by a right turn to fly an outbound track that will position the aircraft most appropriately for the turn back inbound to the holding fix.
39
HOLD LENGTH
The altitude of the aircraft determines the length of the inbound leg the aircraft will fly: at or below 14 000 feet ASL – one minute legs, above 14 000 feet ASL – one-and-half minute legs.
40
MATS ACC > Traffic Management > Enroute Operations > Holding > Holding Patterns (Excerpt) If you are holding an aircraft at a fix that has no established holding area and is not depicted on enroute or IFR terminal charts, as appropriate, you should:
* Assign a standard holding pattern, unless a non-standard holding pattern is required. * Hold aircraft on the side of the fix that will be used for the instrument approach procedure. * Hold military jet aircraft, other than a transport aircraft, on the side of the fix opposite to that used for the penetration procedure.

45
MATS ACC > Traffic Management > Clearances and Instructions > Issuing and Relaying > Delivery Limitations The communication agency, such as the FSS, FIC, CARS, dispatcher (in emergencies), or others to which a clearance is issued is responsible for transmitting the clearance to the aircraft immediately upon receipt, unless an attempt-delivery time has been specified. If a communication agency informs you that a clearance has not been delivered, instruct the agency to do one of the following depending on your situation:
* Continue attempting to deliver, and report if undelivered by a specified time. * Attempt to deliver at a specified time. * Cancel the clearance. You will be notified if the clearance is not delivered within 3 minutes after receipt, or the specified attempt‑delivery time.
