Introduction Canadian airspace is divided into many regions and areas.Canadian airspace is divided into many regions and areas. Pilots must know where these areas are, and what the rules and procedures for them are.Pilots must know where these areas are, and what the rules and procedures for them are.

Domestic Airspace Canadian Domestic Airspace (CDA)Canadian Domestic Airspace (CDA) –All airspace over Canadian land mass, Canadian Arctic and Archipelago and certain areas over high seas Northern Domestic Airspace (NDA)Northern Domestic Airspace (NDA) –Close to magnetic north pole –Compass unreliable, therefore true tracks are used Southern Domestic Airspace (SDA)Southern Domestic Airspace (SDA) –Most of settled Canada in SDA –Magnetic tracks are used

Domestic Airspace

Altimeter Regions Altimeter Setting RegionAltimeter Setting Region –Before take-off, landing and during flight, pilot will set altimeter to nearest aerodrome –If no altimeter setting, set to elevation –Includes all airspace in SDA below 18,000 ft Standard Pressure RegionStandard Pressure Region –Altimeter set to 29.92’ Hg –Includes all airspace in NDA –Includes all airspace in SDA above 18,000 ft

Airspace High Level AirspaceHigh Level Airspace –All airspace 18,000 feet and above –Usually controlled airspace Low Level AirspaceLow Level Airspace –All airspace below 18,000 –May be controlled or uncontrolled Built-Up AreasBuilt-Up Areas –Aircraft must stay at least 1000 ft over highest obstacle within 2000 ft radius Controlled AirspaceControlled Airspace –Where an Air Traffic Control service is provided

Airspace Classes Class AClass A –Controlled, only IFR permitted –Includes all controlled airspace between 18,000 ft and FL 600 Class BClass B –Controlled for VFR and IFR –Includes all airspace between 12,500 ft and 18,000 ft Class CClass C –Controlled for VFR and IFR –VFR must have clearance to enter, separation may be provided –Becomes Class E when ATC closed Class DClass D –Controlled for VFR and IFR –VFR must communicate with tower, separation not provided –Becomes Class E when ATC closed

Airspace Classes Class EClass E –Controlled for IFR –Uncontrolled for VFR Class F - AdvisoryClass F - Advisory –Aircraft can enter with caution, but encouraged not to –Used for gliding, skydiving, etc Class F - RestrictedClass F - Restricted –Aircraft must not enter without permission –Used for air shows, military training etc Class GClass G –Uncontrolled airspace
