Classification Of Canadian Airspace

Question 1

Division of Canadian Domestic Airspace (CDA)

Answer 1

Laterally:
Northern Domestic Airspace (NDA)
Southern Domestic Airspace (SDA)
Vertically:
High level airspace (18000ft ASL and above)
Low level airspace (below 18000ft ASL)

Question 2

Class A

Answer 2

Altitude 18000 or above (IFR only)

ATC separation is provided to all aircraft

Question 3

Class B

Answer 3

Below 18 000 above 12 500

Primarily for IFR, VFR flights are permitted

ATC separation is provided to all aircraft

Question 4

Class C

Answer 4

Clearance required

VFR flights require ATC clearance to enter

ATC separation is provided to all IFR aircraft

Becomes Class E airspace if the appropriate ATC unit is not in operation

Question 5

Class D

Answer 5

Dialogue required

VFR flights do not require ATC clearance to enter but must establish 2 way communication with the appropriate ATC prior entering

ATC separation is provided to all IFR aircraft

becomes Class E airspace if the appropriate ATC unit is not in operation

Question 6

Class E

Answer 6

Easy for VFR (everywhere else)

exists where there’s an operation need for controlled airspace but the requirements for Class A/ B/ C/ D airspace are not met

All airports serviced by flight service stations have Class E airspace around them

ATC separation provided to IFR aircraft only

Question 7

Class G

Answer 7

General airspace

uncontrolled domestic airspace

no ATC services provided

Question 8

Class F

Answer 8

Fancy airspace

-Advisory
-Restricted
-Danger

Question 9

Class F airspace: advisory

Answer 9

VFR flights should avoid area (if possible)

IFR flights not permitted, unless pilot obtained permission

Question 10

Class F airspace: restricted

Answer 10

aircraft are kept clear of restricted areas by appropriate lateral/ vertical minimum

(ex. areas of high military importance/ high speed pilot training)

Question 11

Class F airspace: danger

Answer 11

activities dangerous to other aircraft might take place (ex. mid air fuelling)

Question 12

Conditions for clearing IFR aircraft in Class F airspace

Answer 12

Permission has been obtained from the user agency
Aircraft is operating on an altitude reservation approval
Aircraft has been cleared for contact/ visual approach

Question 13

IFR aircraft will be separated by ____ ft from active Class F airspace, and _____ ft if wake turbulence separation is applicable

Answer 13

500

1000
