401. 06 AIRSPACES • Airspace Classes (A through G) • Confirmation Activity – Airspace Model Labelling

REVIEW - CONTROLLED AIRSPACE • "controlled airspace" - means an airspace of fixed dimensions that is so specified in the Designated Airspace Handbook and within which air traffic control service is provided.

CLASS A AIRSPACE VFR Flight in Class A Airspace (CAR 601. 06) (1) No person shall operate a VFR aircraft in Class A airspace unless the aircraft is operated in accordance with an authorization issued by the Minister. (2) The Minister may issue an authorization referred to in subsection (1) where the operation of the aircraft is in the public interest and is not likely to affect aviation safety. (3) All Flights require an ATC clearance to enter Class A airspace.

CLASS A AIRSPACE • “High Level Airspace” | Above 18000’ ASL in Southern Domestic Airspace • Generally, controlled IFR traffic only

CLASS B AIRSPACE • VFR Flight in Class B Airspace (CAR 601. 07) • (1) No person shall operate a VFR aircraft in Class B airspace unless the aircraft is operated in accordance with an air traffic control clearance or an authorization issued by the Minister. • (2) The Minister may issue an authorization referred to in subsection (1) where the operation of the aircraft is in the public interest and is not likely to affect aviation safety. • (3) The pilot-in-command of a VFR aircraft operating in Class B airspace in accordance with an air traffic control clearance shall, when it becomes evident that it will not be possible to operate the aircraft in VMC at the altitude or along the route specified in the air traffic control clearance, • (a) where the airspace is a control zone, request authorization to operate the aircraft in special VFR flight; and • (b) in any other case, • (i) request an amended air traffic control clearance that will enable the aircraft to be operated in VMC to the destination specified in the flight plan or to an alternate aerodrome, or • (ii) request an air traffic control clearance to operate the aircraft in IFR flight.

CLASS B AIRSPACE • “Low Level Airspace” | Above 12500’ – 18000’ ASL • IFR and Controlled VFR Traffic – all Aircraft receive ATC service Oxygen required if flying above 10000’ for greater than 30 minutes, or above 13000’

CLASS C AIRSPACE • VFR Flight in Class C Airspace (CAR 601. 08) • (1) Subject to subsection (2), no person operating a VFR aircraft shall enter Class C airspace unless the person receives a clearance to enter from the appropriate air traffic control unit before entering the airspace. Pilot must hold either a valid pilot’s licence or a student pilot permit • (2) The pilot-in-command of a VFR aircraft that is not equipped with radiocommunication equipment capable of two-way communication with the appropriate air traffic control unit may, during daylight in VMC, enter Class C airspace if the pilot-in-command receives authorization to enter from the appropriate air traffic control unit before entering the airspace. • (3) Class C airspace becomes Class E airspace when the appropriate air traffic control unit is not in operation.

CLASS C AIRSPACE • Controlled airspace, IFR and VFR aircraft permitted, clearance to enter required • Often, transponder with pressure altitude transmission required (Mode C)

WHAT SHAPE ARE CONTROL ZONES?

CLASS D AIRSPACE • VFR Flight in Class D Airspace (CAR 601. 09) • (1) Subject to subsection (2), no person operating a VFR aircraft shall enter Class D airspace unless the person establishes two-way radio contact with the appropriate air traffic control unit before entering the airspace. • (2) The pilot-in-command of a VFR aircraft that is not equipped with radio communication equipment capable of two-way communication with the appropriate air traffic control unit may, during daylight in VMC, enter Class D airspace if the pilot -in-command receives authorization to enter from the appropriate air traffic control unit before entering the airspace. • (3) Class D airspace becomes Class E airspace when the appropriate air traffic control unit is not in operation.

CLASS D AIRSPACE • Controlled airspace; IFR and VFR traffic permitted • Two-Way communication required before entry

CLASS E AIRSPACE • Class E airspace is designated where an operational need exists for controlled airspace but does not meet the requirements for Class A, B, C, or D. • Operations may be conducted under IFR or VFR. ATC separation is provided only to aircraft operating under IFR. There are no special requirements for VFR. • Aircraft are required to be equipped with a transponder and automatic pressure altitude equipment to operate in Class E airspace that is specified as transponder airspace (see the TC AIM: RAC 1. 9. 2). • Low level airways, control area extensions, transition areas, or control zones established without an operating control tower may be classified as Class E airspace.

CLASS E AIRSPACE • Controlled airspace • ATC service to IFR traffic; no requirements for VFR traffic • Nighttime closed towers, airways, control zone extensions, transition areas…

CLASS F AIRSPACE • Class F Airspace (CAR 601. 04) • IFR or VFR Flight in Class F Special Use Restricted Airspace or Class F Special Use Advisory Airspace • (1) The procedures for the operation of aircraft in Class F Special Use Restricted airspace and Class F Special Use Advisory airspace are those specified in the Designated Airspace Handbook. • (2) No person shall operate an aircraft in Class F Special Use Restricted airspace unless authorized to do so by the person specified for that purpose in the Designated Airspace Handbook.

CLASS F DESIGNATIONS • Part a) will consist of the nationality letters "CY"; and • Part b) will consist of the letter "D" for Danger Area, "R" for Restricted Area or the letter "A" for Advisory Area; and • Part c) will consist of a three-digit number which will identify the area

CLASS G AIRSPACE • Class G airspace is airspace that has not been designated Class A, B, C, D, E or F, and within which ATC has neither the authority nor the responsibility to exercise control over air traffic. • However, ATS units do provide flight information and alerting services. The alerting service will automatically alert SAR authorities once an aircraft becomes overdue, which is normally determined from data contained in the flight plan or flight itinerary. • In effect, Class G is all uncontrolled domestic airspace.
