Canadian Domestic Airspace Flashcards
northern domestic airspace
-uses true track
southern domestic airspace
-magnetic track
altimeter setting region
all airspace below 18000ft asl
before takeoff set to aerodrome setting if not set to airport elevation, enroute should be set to nearest station, landing set to aerodrome setting
standard pressure region
all airspace above 18000ft asl as well as any low- level airspace which is outside the altimeter setting region. before takeoff- aerodrome setting or field elevation, enroute- immediately prior to reaching flight level change to 29.92’’ Hg arrival- before landing chnage to airport elevation
HOWEVER if holding procedure is conducted do not change to airport setting until below holding level
transitions between standard region and altimeter setting region
if in level cruise then get the nearest setting prior to entering region.
if ascending into standard pressure change to 29.92 immediately after entering, if descending into altimeter setting region change immediately prior to descending
the three high level controlled airspaces
SCA - southern control area- 18000ft and up
NCA- northerns control area- FL230 and up
ACA- arctic control area - FL270 and up
Class A airspace
(airlines)
-IFR only
-18000ft asl to FL600
- required to follow ATC
Class B airspace
-IFR or controlled VFR
-12500ft asl to 18000ft asl
- control zones and associated terminal control areas may be class B
Class C airspace
-IFR and VFR
-ATC provides traffic separations
-terminal control areas and associated control zones maybe class C
-when tower is closed it is class E
Class D airspace
-IFR and VFR
-terminal control areas and associated control zones maybe class C
-when tower is closed it becomes class E
similar to c but smaller
Class E airspace
-IFR and VFR
-seperation is applied to only IFR unless requested
-also airspace above FL600
-airports without towers
Class F airspace
-advisory or restricted
Class G airspace
-uncontroled
-IFR and VFR
-low level air routes (same as low level airways but start at earths surface and are uncontrolled)
what is a low level airway and whats its heights
a controlled airspace 2200ft agl to 18000ft asl
what are the 3 types of low level airways and their dimensions ?
- VHF/UHF (VOR) airways - 4NM on each side of centerline to a distance of 50.8NM from VOR then the airway width increases at 4.5°
- LF/MF (NDB) airways - 4.34NM on each side of center line to a distance of 49.66NM the diverging at 5°
- LF/MF connecting to VHF airway - same dimensions as LF/MF (NDB) airways
