“Yes, but is there any air in space?”
MTPs
 Divisions of Domestic Airspace
 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
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
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
Divisions of Airspace
 Based on Control:
 High Level Airspace
 Low Level Airspace
Divisions of Airspace
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)
Pressure Regions
 Standard Pressure Region
 Anything in NDA, and/or above 18 000’ 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 = 18 000’
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.
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
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
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
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
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
Classification of Airspace
 Class B
 All airspace from FL 125 up to but not including 18 000’
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
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?
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 126.7 MHz.
 442 indicates the area, in this case Manitoba
 These areas may be created by NOTAMs (ie, not appear on
charts)
