PAULS BOUTIQUE Flashcards
Minimum IFR Altitude can be:
++++++++++++++++++++++++
- MEA - minimum enroute altitude
- MOCA - minimum obstacle clearance
- MSA - minimum sector altitude
- MVA - minimum vectoring altitude
- TAA - terminal arrival area
- AMA - area minimum altitude
- Safe altitude 100 N
- Transition altitude
- Missed approach altitude
MATS ACC > Traffic Management > Enroute Operations > Altitude > Minimum Altitudes
++++++++++++++++++++++
If a pilot requests it, you may approve an altitude that is below the MEA, but is at or above the MOCA, for any of the following reasons:
- Flight safety
- Flight check of a NAVAID
- A MEDEVAC flight
- GNSS navigation
GNSS provides adequate navigation accuracy along the entire route segment.
TO BE MAINTAINING AN ALTITUDE
ITS ALTITUDE READOUT IS WITHIN 200 FEET OF ASSIGNED ALTITUDE
TO HAVE REACHED AN ALTITUDE
ITS ALTITUDE READOUT HAS BEEN WITHIN 200 FEET OF ASSIGNED ALTITUDES FOR 4 CONSECUTIVE SWEEPS
TO HAVE VACATED AN ALTITUDE
THE ALTITUDE READOUT HAS CHANGED BY 300 FEET OR MORE, IN THE APPROPRIATE DIRECTION, FROM THE VALUE THAT PREVAILED WHILE THE AIRCRAFT WAS IN LEVEL FLIGHT
TO HAVE PASSED AN ALTITUDE
THE ALTITUDE HAS CHANGED BY 300 FEET OR MORE IN THE APPROPRIATE DIRECTION
MATS ACC > ATS Surveillance > Identification > Identification Doubtful or Lost
+++++++++++++++++++++++++++++
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.
When identification is lost, inform the pilot.
MATS ACC > ATS Surveillance > Identification > Identification Doubtful or Lost
++++++++++++++++++++++++
Identification may be be doubtful due to:
- The position or movement of other aircraft
- The observation of more than 1 aircraft responding to an identification procedure
- Temporary loss of the PPS
- Coasting of PPS
- Merging of PPS
- Ambiguous PPS
- Display Clutter
- Other Circumstances
MATS ACC > Traffic Management > Traffic Information (Excerpt)
++++++++++++++++++
Provide traffic information to all concerned aircraft if any of the following apply:
- You clear an IFR aircraft to fly in accordance with VFR.
- You clear an aircraft to maintain at least 1000 feet on top.
- A pilot requests it.
- Multiple aircraft are holding at the same fix and are separated by the vertical separation minimum.
- A pilot acknowledges an avoidance instruction.
- You consider it necessary.
MATS ACC > Separation > Separation Basics > Control Estimates(Excerpt)
++++++++++++++
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:
- Check the accuracy of the ATC estimate.
- If a discrepancy remains, request the pilot to check the aircraft estimate.
- If a discrepancy still exists, take appropriate action to ensure that separation is not compromised.
MATS ACC > Traffic Management > Clearances and Instructions > IFR Clearance Format
++++++++++++++++++++++++++++++++++++
Issue clearance items, as appropriate, in the following order:
- Prefix/aircraft ID
- Clearance limit
- SID
- Route
- Altitude
- Speed
- Departure, enroute, approach, or holding instructions
- Special instructions or information, may include an SSR code
- Traffic information
MATS ACC > ATS surveillance > Vectoring > Vectoring into Class G Airspace
You may vector an aircraft into Class G airspace if…
… you inform the pilot and obtain the pilot’s approval.
MATS ACC > Traffic Management > Enroute Operations > Holding > Holding Clearances
When issuing a holding clearance, issue an…
- expect-approach-clearance time,
- an expect-further-clearance time,
- the time to depart the fix, and revise it as necessary.
MATS ACC > Traffic Management > Clearances and Instructions > IFR Clearance Format > Clearance Limit
5 minutes or more before an aircraft reaches its clearance limit, issue one of the following:
- Further clearance
- Approach clearance
- Holding clearance

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.
MATS ACC > Glossary
SVFR (special VFR flight)
A visual flight authorized by an ATC unit to operate within a control zone under meteorological conditions that are below visual meteorological conditions
In an ATS environment, you may omit the name of the airport from an approach clearance provided:
+++++++++++++++++
- The aircraft is identified and monitored until established on final approach.
- There is no likelihood of misunderstanding

0 AGL - 2200 AGL
0 AGL - 12500 AGL (CROSSHATCHED)
NORTH BORDER: 0 AGL-FL180
MATS ACC > Flight Information > Weather Information > Altimeter Setting Information
Issue the altimeter setting as follows:
- If the setting is …… state the setting twice.
28.99 or lower, or 31.00 or higher
MATS ACC > Glossary
MINIMUM IFR ALTITUDE
The lowest IFR altitude established for use in a specific airspace.
Depending on the airspace concerned, the minimum IFR altitude may be a minimum obstacle clearance altitude (MOCA), a minimum enroute altitude (MEA), a minimum sector altitude (MSA), a minimum vectoring altitude (MVA), a safe altitude 100 NM, a terminal arrival area (TAA), an area minimum altitude (AMA), a transition altitude, or a missed approach altitude. The minimum IFR altitude provides obstacle clearance, but may or may not be within controlled airspace
MATS ACC > Glossary
MINIMUM OBSTACLE CLEARANCE ALTITUDE (MOCA)
The altitude above sea level between specified fixes on airways or air routes that meets the IFR obstacle clearance requirements for the route segment in question.
This altitude is published on aeronautical charts.
MATS ACC > Glossary
MINIMUM ENROUTE ALTITUDE (MEA)
The altitude above sea level between specified fixes on airways or air routes that assures acceptable navigational signal coverage and that meets the IFR obstacle clearance requirements.
This altitude is published on aeronautical charts
MATS ACC > Glossary
MINIMUM SECTOR ALTITUDE (MSA)
The lowest altitude that will provide a minimum clearance of 1000 ft under conditions of standard temperature and pressure above all objects located in an area contained within a sector of a circle with a 25 NM radius centred on a radio aid to navigation or a specified point.
