Air Law - Airspace
“Yes, but is there any air in space?”

2. MTPs Divisions of Domestic Airspace Pressure Regions
Northern vs. Southern
Cruising Altitudes
Low Level vs. High Level
Pressure Regions
Altimeter Setting Region
Standard Pressure Region
Classifications of Canadian Airspace
Class A,B,C,D,E,F,G

3. Divisions of Airspace Cruising Altitudes “Easterners are odd”
“Oddballs fly east”
Odysseus spent 10 years travelling from the east
0-179 degrees, fly odd thousands plus 500’
180 – 359 degrees, fly even thousands plus 500’
Only mandatory above 3000’ AGL

4. Divisions of Airspace Southern Domestic Airspace
Runways numbered by magnetic heading
Cruising altitude determined by magnetic heading
Northern Domestic Airspace
Runways numbered by true heading
Cruising altitude determined by true heading

5. Divisions of Airspace Based on Control: High Level Airspace
Anything above ’ ASL in SDA
Above ’ ASL in Northern Control Area, and ’ in the Arctic Control Zone
Low Level Airspace
Uncontrolled unless otherwise stated.

6. Divisions of Airspace

7. Pressure Regions Altimeter Setting Region Area same as SDA
Altimeter set to setting of airport prior to takeoff
If not available, set to field elevation of aerodrome – gives the setting
During flight, set to the setting of the nearest station en route
Prior to landing, set to the setting of your destination airport. (Essentially the same as above)

8. Pressure Regions Standard Pressure Region
Anything in NDA, and/or above ’ ASL
During cruise in the region, set altimeter to setting of 29.92’’ Hg
Do this prior to attainment of cruising altitude or just prior to attainment of FL 180, whichever comes first (FL 180 = ’ ASL)
Prior to takeoff and prior to beginning landing descent, set altimeter to setting of departure/arrival aerodrome
When x-iting to Alt. Setting Region, set to nearest aerodrome prior to entry of ASR.

9. Classification of Airspace
Lettered A-G
In “Controlled Airspace” (A-E), a controller may issue a clearance or an instruction
ATC Clearance: Need not be followed until accepted
ATC Instruction: Must be complied with when received

10. Classification of Airspace
Class G
Anything not designated as class A, B, C, D, E, or F
Both VFR and IFR may operate here – no special requirements placed on either

11. Classification of Airspace
Class E
Controlled airspace where there might be a need for some kind of traffic separation
Eg, Control Area Extension
Separation provided for IFR traffic only
No special requirements on VFR traffic, NORDO permitted

12. Classification of Airspace
Class D
Like Class E, only this is more specific to the areas directly connected to the aerodrome
Eg, Control Areas & Control Zones
Differences:
Separation provided (where possible) for both IFR and VFR
VFR Restrictions:
Must establish 2-way radio contact prior to entry, maintain listening watch on frequency
NORDO only w/ prior permission

13. Classification of Airspace
Class C
Similar role to Class D
Differences:
Conflict resolution provided to all identified aircraft
VFR Restrictions:
VFR must obtain clearance prior to entry, maintain listening watch
Must be equipped with a Class C transponder (Alt/Code)
NORDO only permitted with prior permission

14. Classification of Airspace
Class B
All airspace from FL 125 up to but not including ’ ASL.
“Low-level controlled airspace”
Differences:
No NORDO permitted
VFR Restrictions:
2-Way Radio Equipment
RNAV equipment to enable flight pursuant to flight plan
Xponder and automatic pressure altitude reporting equipment

15. Classification of Airspace
Class A
All airspace FL 180 and up (to FL 600)
VFR not permitted, except as authorized by TC and ATC where it may be “in public interest”
NB: This is in… (standard/altimeter setting?) pressure region; what are altimeters set to?

16. Classification of Airspace
Class F
Airspace containing activities which may or may not present a hazard to aircraft
Encoded on charts by a three-letter/3-number identifier
Letters indicate degree of restriction; the numbers, the geographic area
Eg, CYA 442
“CY” means Canadian
“A” means advisory, “D” for Danger”, “R” for Restricted
Only “A” may be entered with out prior permission
Generally, the frequency in such an area will be MHz.
442 indicates the area, in this case Manitoba
These areas may be created by NOTAMs (ie, not appear on charts)
