PARAMETERS OF RVSM
FL 290 - FL 410
MATS ACC > Traffic Management > Enroute Operations > Altitude> Altitude Instructions > RVSM
+++++++++++++++++++++++++
Do not clear a non-RVSM aircraft to enter RVSM airspace unless the aircraft is any of the following:
- A state aircraft
- On an initial delivery flight
- An aircraft that was formerly RVSM-certified but has experienced an equipment failure and is being flown to a maintenance facility for repair/recertification
- A mercy or humanitarian flight
- A photographic survey aircraft
- Conducting a flight check of a NAVAID
- Conducting a monitoring/certification or developmental flight
Operators are permitted to file a flight plan to conduct the climb/descent through RVSM airspace only if….
+++++++++++++++++++++++++++++
… the aircraft is capable of a continuous climb/descent through RVSM airspace at a normal rate and does not need to level off at an intermediate altitude for operational considerations
MATS ACC > Traffic Management > Enroute Operations > Altitude > Altitude Instructions > RVSM
+++++++++++++++++++++++
Provided a non-RVSM aircraft will be separated from other aircraft by the applicable vertical, lateral, or longitudinal separation minimum, you may do either of the following:
- Clear the aircraft to climb or descend through RVSM airspace.
- Level-off the aircraft in RVSM airspace for traffic management
MATS ACC > Traffic Management > Clearances and Instructions > Amending Clearances or Instructions
++++++++++++++++++++++++
If a pilot requests a flight plan change:
- Approve the change and include the exact nature of the change in the clearance.
- If you are unable to approve the change, provide the following to the pilot:
◦ The reason for non-approval
◦ If appropriate, a suggested alternative
MATS ACC > Traffic Management > Enroute Operations > Altitude > Altitude Instructions > Wrong-Way Altitude Assignment
You may assign an altitude inappropriate to the direction of flight in the following situations:
++++++++++++++++++++++=
- The following conditions apply:
◦ No alternate separation minima can be applied.
◦ The altitude has been approved by affected sectors/units.
◦ The aircraft will be cleared to an appropriate altitude as soon as the conditions permit. - The airspace is structured for one-way traffic flow
- Transitioning to or from oceanic airspace within 200 miles along the aircraft track from the oceanic entry or exit point
- A pilot requests the altitude because of icing, turbulence, or fuel considerations and the following apply:
◦ The pilot informs you of the time or location that the aircraft can be cleared to an appropriate altitude
◦ The altitude has been approved by affected sectors/units
MATS ACC > Traffic Management > Enroute Operations > Altitude > Altitude Instructions > Wrong-Way Altitude Assignment
+++++++++++++++++++++++=
You may assign an altitude inappropriate to the direction of flight in the following situations:
- An aircraft is doing any of the following:
◦ Operating on a polar route
◦ Engaged in an aerial survey, mapping flight, or test flight
◦ Transitioning to or from oceanic airspace within 200 miles along the aircraft track from the oceanic entry or exit point
◦ Conducting a flight check of a NAVAID
◦ Holding
◦ Operating within an altitude reservation
◦ Arriving
◦ Departing
MATS ACC > Traffic Management > Enroute Operations > Altitude > Altitude Instructions > Wrong-Way Altitude Assignment
If a cruising altitude inappropriate to the direction of flight is assigned:
- Instruct the pilot to make position reports.
- Identify the altitude as WRONG WAY for any of these coordination tasks:
◦ Passing and receiving a control estimate
◦ Giving and receiving a handoff
◦ Coordinating with an adjacent sector/unit - Post warning indicators by using the wrong-way altitude alerting function, if possible.
- Before transferring control, inform the receiving controller of the reason for the assignment.
MATS ACC > Traffic Management > Enroute Operations > Altitude > Altitude Instructions > Wrong-Way Altitude Assignment
++++++++++++++++++++++
Issue vectors or offset tracks to establish an aircraft at least 5 miles from the centreline of the airway or published track otherwise authorized if:
- The aircraft is in high-level surveillance-controlled airspace.
- You are assigning an altitude inappropriate to the direction of flight in one of the following situations:
◦ No alternate separation minima can be applied.
◦ A pilot requested an inappropriate altitude because of icing, turbulence,
or fuel considerations, and has informed you of the time or location at which the flight can be cleared to an appropriate altitude that has already been approved by affected sectors or units. - The airway or published track is shown on the display.
MATS ACC > Separation > ATS Surveillance Separation > ATS Surveillance Separation Using Parallel Offset
+++++++++++++++++++++
You may use parallel offset techniques in a ATS surveillance environment, provided:
- The pilot confirms the capability to offset.
- The minimum offset value ensures the appropriate ATS surveillance separation minimum will exist.
- You cancel the parallel offset when it is no longer required.
MATS ACC > Traffic Management > Enroute Operations > Altitude > Altitude Instructions > Block Altitude
On pilot request, you may assign a block altitude, provided that you adhere to procedures contained in Wrong-Way Altitude Assignment, and one of the following two conditions applies:
- There are icing, turbulence, or fuel considerations, and the following apply:
◦ The pilot informs you of the time or location that the aircraft can be cleared to an appropriate altitude.
◦ The altitude has been approved by affected sectors/units. - The pilot is on an IFR training flight, MEDEVAC flight, or is flight-checking a
NAVAID.
MATS ACC > Traffic Management > Enroute Operations > Altitude > Altitude Instructions > Block Altitude
If the aircraft is conducting an aerial survey, mapping flight, test flight, or special military activity, you may approve a block altitude, provided that you identify the altitude as BLOCK for any of the following coordination tasks:
- Passing and receiving a control estimate
- Giving and receiving a handoff
- Coordinating with an adjacent sector/unit
MATS ACC > Separation > ATS Surveillance Separation > ATS Surveillance Separation For Aircraft on Reciprocal Tracks
For aircraft on reciprocal tracks in an ATS surveillance environment, you may discontinue vertical separation if you observe on the situation display that the aircraft have passed:
PPS DOES NOT OVERLAP
- ALTITUDE DISPLAYED FOR BOTH AIRCRAFT
OR - BOTH AIRCRAFT ARE AT OR BELOW 15000 ASL
