Block 3 Glossary Flashcards
Define Minimum IFR Altitude
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.
Define MOCA
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.
Define MEA
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.
Define AMA
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.
Define MSA
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
Define MVA
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
Define STAR
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.
Define Transition
MATS ACC > Glossary
TRANSITION - 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.
Define Fly-Over Waypoint
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.
Define Fly-By Waypoint
MATS ACC > Glossary
FLY-BY WAYPOINT - A waypoint that requires the use of turn anticipation to avoid an overshoot of the next flight segment.
Define Waypoint
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
Define Wind Shear
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.
Define Wake Turbulence
MATS ACC > Glossary
WAKE TURBULENCE - Turbulent air behind an aircraft caused by any of the following:
* Wing-tip vortices
* Rotor-tip vortices
* Jet-engine thrust stream or jet blast
* Rotor downwash
* Prop wash
Define Light Aircraft
MATS ACC > Glossary
LIGHT AIRCRAFT - For wake turbulence categorization purposes, an aircraft certificated for a maximum take-off weight of 7000 kilograms (15500 pounds) or less.
Define Medium Aircraft
MATS ACC > Glossary
MEDIUM AIRCRAFT - For wake turbulence categorization purposes, an aircraft certificated for a maximum take-off weight of more than 7000 kilograms (15500 pounds) but less than 136000 kilograms (300000 pounds).
