Airspace Flashcards
(51 cards)
This is airspace within which Air Traffic Control services are provided.
Controlled Airspace
All airspace over the Canadian land mass, the Canadian arctic and Archipelago and certain areas over the high seas. It is divided into two areas, the Northern Domestic Airspace and the Southern domestic Airspace. The base of the Southern domestic airspace is at the US Canadian boarder.
The Canadian Domestic Airspace
In close proximity to the north magnetic pole. Where the Earth’s lines of force dip vertically towards the pole, and the compass (which lies in a horizontal plane) loses its ability to point the way. That is, the magnetic North Pole is located near the center of this airspace, therefore magnetic compass indications may be erratic. Thus, in this airspace, runway heading is given in true and true track is used to determine cruising altitude for direction of flight in lieu of magnetic track.
Northern Domestic Airspace
All aircraft in level cruising flight within this region must maintain an altitude or flight level that is appropriate to their direction of flight as determined by the magnetic track.
In this region, all airways and air routes are based on magnetic tracks. Airport runways are assigned numbers based on their magnetic bearing. Surface winds are reported in magnetic degrees.
Southern Domestic Airspace
Additional airspace divisions that have been designated in order to increase safety or make allowances for the remote or mountainous regions within Canada.
A) Altimeter setting region
B)Standard pressure region
C) Designated mountainous region
This is an airspace below 18,000 feet ASL. Specific altimeter setting procedures exist here.
Altimeter Setting Region
Region where all airspace is at or above 18,000 feet ASL. Includes some low-level airspace that is outside the lateral limits of the Altimeter Setting Region. All aircraft must set their altimeters to standard pressure 29.92 inHg unless otherwise instructed. This ensures all aircraft use the same reference for altitude, preventing discrepancies.
Standard Pressure Region.
These are the divisions of airspace based on altitude in the Canadian Domestic Airspace (CDA).
Low-level airspace (below 18,000 ft ASL) and high-level airspace (18,000 ft ASL and above)
“This is the term for the airspace where air traffic control (ATC) manages aircraft and provides active service.”
Controlled airspace?”
“These are large areas above 18,000 ft where ATC provides services for aircraft, including high-level airways, military terminal control areas, and terminal control areas.”
Southern, Northern, and Arctic Control Areas?
This area in Canadian airspace, which includes all airspace above 18,000 feet ASL, has controlled air traffic.
What is the Southern Control Area?
This control area in Canada extends from the northern limits of the Southern Control Area up to around the 72nd parallel north, and comprises all airspace at and above flight level 230.
What is the Northern Control Area?
This airspace region extends north from the Northern Control Area to the North Pole, it comprises all airspace at and above flight level 270, and has controlled traffic within it.
What is the Arctic Control Area?
This type of controlled airspace extends from the surface up to 3,000 feet AAE (above aerodrome elevation) (unless otherwise specified). It usually has a 5 NM radius but can vary in size. It surrounds airports with a control tower and facilitates the control of IFR and VFR traffic. In Class C or D, you need ATC clearance to enter.
What is a Control Zone (CZ)
On pilotage charts, these boundaries are indicated by shaded lines, with the solid edge defining the outer limits.
The boundaries of controlled low level airspace.
Not all of the low level airspace in Canada falls under this category, meaning it is not subject to direct ATC control.
What is uncontrolled airspace.
This classification of airspace includes all airspace within Canadian domestic airspace below 18,000 feet ASL.
What is low level airspace?
These designated routes allow aircraft to navigate between points using signals from NDBs or VORs.
What are low level airways?
Also known as Victor airways, these airways use radials projected from VHF omnidirectional range stations located approximately 100 miles apart.
What are VHF/UHF airways?
These airways use signals from low-frequency transmitters such as non-directional beacons for navigation.
What are LF/MF airways?
This is the basic width of a VHF/UHF airway on each side of the centerline.
What is 4 nautical miles?
The width of an LF/MF airway extends this distance on each side of the centerline.
What is 4.34 nautical miles?
Unless otherwise published, a low level airway has its base at this altitude above ground level.
What is 2,200 feet AGL?
The portion of a low level airway that extends from 12,500 feet to 18,000 feet ASL is classified under this airspace category.
What is Class B airspace?
