Canadian Domestic Airspace
Divided into:
Northern Domestic Airspace - NDA
Southern Domestic Airspace - SDA
NDA uses used True tracks for
navigation
SDA uses Magnetic tracks for
navigation
Canadian Domestic Airspace
Further broken into:
• High level airspace > 18000’ ASL
– Contains Arctic, Northern, and Southern Control
Areas
• Low level airspace < 18000’ ASL
– Contains

Classes of Airspace
Classes of Airspace
• Airspace is further broken into classes
based on what aircraft and what
equipment is needed to fly into particular
areas
• The are given a letter from A to G
• The next slide is an overview, we will
discuss each class
Classes of Airspace
Classes of Airspace
•
•
•
•
Class A
Only aircraft on an IFR flight plan may fly in this class
All aircraft must have a radio for 2 way communication
All aircraft must have a transponder (gives altitude and
position information to ATC)
Goes from 18000’ ASL to 60000’ ASL
Classes of Airspace
•
•
•
•
Class B
IFR and Controlled VFR aircraft
All aircraft must have a radio for 2 way
communication
All aircraft must have a transponder
Goes from 12500’ ASL to 17999’ ASL
Classes of Airspace
•
•
•
•
•
Class C
IFR and VFR aircraft (VFR aircraft need clearance to enter)
All aircraft must have a radio for 2 way communication
All aircraft must have at transponder
Often this airspace is around an airport
Goes from ground to a specified altitude, no cap given
Classes of Airspace
Class D
• IFR and VFR aircraft
• VFR aircraft have to make contact prior to entering the
zone
• Often this airspace is around an airport
• Very similar to class C however is used around airports
with less traffic
Classes of Airspace
•
•
•
•
Class E
IFR and VFR, no requirements for VFR aircraft
Used when there is operational need to have controlled airspace but
does not meet the requirements of A, B, C, or D airspace
Often designated around an airport or for Low Level Airways
Low level airways extend from the ground to 2200’ AGL
Classes of Airspace
Class F
• Restricted Airspace
• Designated when due to the nature of the activities this airspace is
unsafe to fly through
•
CYA – Advisory
CYR – Restricted
• May fly through CYA airspace, need permission to fly into CYR
airspace
• Altitudes and times will be given on a map
Classes of Airspace
•
•
•
•
Class G
Uncontrolled Airspace
All airspace not designated A, B, C, D, E or F
ATC has no responsibility or authority
Any aircraft may fly here, no special equipment
needed
Classes of Airspace
Confirmation
• Select the number (s) that correspond to the correct
class of airspace
A

G
1 – Radio req’d
2 – Transponder req’d
3 – CYR
4 – Uncontrolled
5 – Control Zone
6 – CVFR available
7 – IFR only
8 – VFR
Altimeter Setting Regions
Before we go flying we must set our
altimeter to the pressure setting at
the station to ensure our altimeters
are reading correctly
The further north you go there are less
weather stations that can give a pilot
the current pressure setting
Therefore regions have been set for
where to set your altimeter to a
pressure setting and where to set
your altimeter to the standard
pressure – 29.92”Hg
Altimeter Setting Region
• Altimeter Setting Region:
– Airspace of defined dimensions
below 18 000ft ASL
– pilot must set altimeter to the
current altimeter setting and if
that is not available, to the
elevation of the aerodrome
• Standard Pressure Region:
– All airspace above 18 000ft
and all airspace outside the
bounds of the altimeter setting
region
– The altimeter is to be set to
29.92” Hg
Altimeter Setting Regions
Types of Controlled Airspace
• Control Zone:
– Defined airspace around an airport extending
from the surface to a specific height
– Designated around certain aerodromes to
keep IFR a/c within controlled airspace during
approaches and to facilitate the control of
VFR and IFR traffic
• Standard control zone
– Radius may be either
5, 7 or 10nm
Types of Controlled Airspace
Control
Zone
Types of Controlled Airspace
Control Area:
A defined area of space in
the vicinity of an airport
located above the control
zone for the purpose of
protecting A/C joining
nearby airways
Types of Controlled Airspace
• Terminal Control Area
– Extended area of control
around a very large and
busy airport
– Ex. Vancouver, Toronto
– Looks like an inverted
wedding cake
VFR Cruising Altitudes
• VFR Cruising Altitudes
– Used for aircraft separation
0 to 179
• Based on TRACK, from 3000’AGL to 12499’ASL
East is least
West is best
