You may vector an aircraft into Class G airspace if:
.. you inform the pilot and obtain the pilot’s approval.
TC AIM GEN 5.1 Area Minimum Altitude (AMA)
The lowest altitude to be used under Instrument Meteorological Conditions (IMC) that will provide a minimum vertical clearance of 1000 ft. or, in a designated mountainous region, 2000 ft., rounded up to the next 100-ft. increment, under conditions of standard temperature and pressure, above all obstacles located in the area specified.
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
The Missed approach altitude is the altitude to which the aircraft must climb if it does not land after an IFR approach. It is found…
… on the CAP Chart.
MATS ACC > Traffic Management > Enroute Operations > Altitude > Minimum Altitudes
Do not approve or assign any altitude that is …
… below the minimum IFR altitude.
Inform the pilot if a requested altitude is below the minimum IFR 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.
MATS ACC > Traffic Management > Enroute Operations > Altitude > Minimum Altitudes > Traversing Airways and Routes
When an aircraft is traversing an airway …
you may clear that aircraft to an altitude that is below the MEA, but is at or above another applicable minimum IFR altitude
An aircraft is considered to traverse an airway when…
The airspace protected for the track of the aircraft infringes on the airspace protect for the airway. An aircraft cleared “via direct” on a track that is coincident with an airway is considered to traverse the airway.
T/F
Aircraft operating at the MOCA may be in uncontrolled airspace
TRUE
T/F
Adequate navigation signal coverage may not always exist below the MEA
TRUE
MATS ACC > Traffic Management > Enroute Operations > Altitude > Minimum Altitudes > MEA Higher or Lower Beyond the Next Fix
If the MEA is higher beyond the next fix…
… clear the aircraft to climb in sufficient
time to enable it to cross the fix at or above the MEA established beyond the fix.
MATS ACC > Traffic Management > Enroute Operations > Altitude > Minimum Altitudes > MEA Higher or Lower Beyond the Next Fix
If the pilot requests an altitude that is lower than the MEA for the leg flown, but the altitude requested is at or above the MEA beyond the next fix…
… do not clear the aircraft to descend below the MEA for the leg flown until after the aircraft passes the fix.
Missed Approach Altitude
The altitude to which the aircraft must climb if it does not land after an IFR approach. It is found on the CAP Chart.
Safe Altitude 100 Nautical Miles
Doesn’t have a formal definition.
It is an altitude, usually found on CAP charts, that is flight checked and approved for use within 100 miles of the geographical centre of the aerodrome as depicted on the CAP chart and meets obstruction clearance requirements
Transition Altitude
In most cases for IFR, it is an altitude specifically shown for an aircraft that is changing (“transitioning”) from enroute to approach.
MATS ACC > Flight Information > Weather Information > Altimeter Setting Information > Altimeter Setting Region
If an aircraft will proceed from the Standard Pressure Region to the Altimeter Setting Region, issue the current altimeter setting …
…before the transition occurs.
TO BE MAINTAINING AN ALTITUDE
ITS ALTITUDE READOUT IS WITHIN 200 FEET OF ASSIGNED ALTITUDE FOR 3 CONSECUTIVE SWEEPS
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 > Altitude Readouts > Altitude Readout Limitations
Use altitude readouts of aircraft under the jurisdiction of another controller to determine aircraft altitudes only if either of the following applies
- The other controller has confirmed the aircraft’s altitude.
- On handoff, the transferring controller does not inform you that an aircraft’s altitude readout is invalid or not validated.
Do not use altitude readouts when the site altimeter setting for the geographic region concerned is below 26.00 or above 33.00.
TIME WHEN VACATED ALTITUDES CANNOT BE USED
IN THE PRESENCE OF SEVERE TURBULANCE
MATS ACC > Separation > Vertical Separation > Maintaining Vertical Separation > Assigning Altitudes
You may assign an altitude only after another aircraft previously at that altitude, or climbing or descending through that altitude, has reported or is observed doing one of the following:
- Vacating or passing the altitude you want to assign
MATS ACC > Separation > Vertical Separation > Maintaining Vertical Separation > Assigning Altitudes
You may assign an altitude only after another aircraft previously at that altitude, or climbing or descending through that altitude, has reported or is observed doing one of the following:
- Vacating or passing the altitude you want to assign
- Vacating or passing an altitude separated by the appropriate minimum from the altitude you want to assign, and one of the following applies:
◦ Severe turbulence exists.
◦ The aircraft previously at the altitude you want to assign has been issued a cruise climb.
The causes of turbulence are grouped in four categories.
One or more of them may be present in a given area at the same time:
- Disturbed airflow resulting from air moving vertically in convective currents
- Disturbed airflow resulting from air moving past or over obstructions such as irregular terrain
- Wind shear
- Wake turbulence
Advantages of Ladder Technique
- Separation assured
- Effective where lateral or longitudinal separation cannot be obtained, or is not yet in place
Disadvantages of Ladder Technique
- Increased workload
- Possible coordination
- Could be restrictive to aircraft

Transition
The general term that describes the change from one phase of flight or flight conditions to another, e.g. transition from enroute flight to the approach or transition from instrument flight to visual flight.
MATS ACC > Flight Information > Weather Information > Altimeter Setting Information
Issue the altimeter setting as follows:
- Identify the setting by the name of the station to which it applies, unless:
◦ The setting applies to the station at which the unit is located.
◦ There is no possibility of misunderstanding.
MATS ACC > Flight Information > Weather Information > Altimeter Setting Information
Issue the altimeter setting as follows:
- If the setting is 28.99 or lower, or 31.00 or higher…
… state the setting twice.
MATS ACC > Flight Information > Weather Information > Altimeter Setting Information
Issue the altimeter setting as follows:
- If the setting is higher than 31.00, issue the actual altimeter setting and …
… confirm that the pilot has set the aircraft altimeter to 31.00.
MATS ACC > Flight Information > Weather Information > Altimeter Setting Information
Issue the altimeter setting as follows:
- If the setting changes by _______, issue a revised altimeter setting.
± 0.02 inches or more
