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

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 Anything above 18 000’ ASL in SDA Above 25 000’ ASL in Northern Control Area, and 27 000’ in the Arctic Control Zone Low Level Airspace Uncontrolled unless otherwise stated.

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)
