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

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.
US: minimum safe altitude
MATS ACC > Glossary
MINIMUM VECTORING ALTITUDE (MVA)
The lowest altitude for vectoring
aircraft by ATC that meets obstacle clearance and radio coverage requirements in the airspace specified.

CRUISE CLIMB
A cruising technique resulting in a net increase in altitude as the aircraft mass decreases. A clearance or instruction to carry out a cruise climb allows the pilot the option of climbing at any given rate, as well as the option of levelling off at any intermediate altitude.
MATS ACC > Glossary
STANDARD TERMINAL ARRIVAL (STAR)
An IFR ATC arrival procedure published in the CAP for use by aircraft with the appropriate navigation capabilities and coded in many GNSS and FMS databases.
MATS ACC > Glossary
TRANSITION
Definition 1: 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
Definition 2: A published procedure used to connect the basic standard instrument departure (SID) to one or more enroute airways or to connect one or more enroute airways to the basic standard terminal arrival (STAR). More than one transition may be published in the associated SID or STAR or RNAV approach
MATS ACC > Glossary
WAYPOINT
A specified geographical location, defined by longitude and latitude, that is used in the definition of routes and terminal segments and for progress reporting purposes
MATS ACC > Glossary
FLY-BY WAYPOINT
A waypoint that requires the use of turn anticipation to avoid an overshoot of the next flight segment.
MATS ACC > Glossary
FLY-OVER WAYPOINT
A waypoint that precludes any turn until the waypoint is overflown and is followed by an intercept manoeuvre of the next flight segment.
MATS ACC > Glossary
WIND SHEAR (WS)
A change in wind speed and/or wind direction in a short distance. It can exist in a horizontal or vertical direction and occasionally in both.

HEAVY AIRCRAFT
For wake turbulence categorization purposes, an aircraft certificated for a maximum take-off weight of 136000 kilograms (300000 pounds) or more, with the exception of aircraft types specified in the super
category in “Aircraft Type Designators and Enhanced Wake Separation” in the ATS Unit Library.
