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

Runways numbered by magnetic heading
Cruising altitude determined by magnetic heading
Northern Domestic Airspace
Runways numbered by true heading

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)
