above FL230 ASL. Arctic control area (ACA) at and above FL270 ASL
In northern domestic airspace, at what elevation is the airspace uncontrolled? - ANS
✓Between FL180 ASL and below the bases of the northern control area (FL230 ASL) and

Where do high level air routes exist? (Give region and elevation) - ANS ✓Only in high level
uncontrolled airspace in northern domestic airspace between FL180 ASL and below the bases
of the northern control area (FL230 ASL) and arctic control area (FL270 ASL)
What are high level airways? - ANS ✓Prescribed tracks between radio aids where traffic
control is provided
What is low level airspace and it's elevation? - ANS ✓All airspace that is below FL180 ASL

Do VFR flights use airways at 1000ft or 500ft levels? - ANS ✓500ft levels
What is a control area extension (CAE)? - ANS ✓Airspace that is established at some
airports to provide controlled airspace for handling IFR traffic

doing approaches
At what elevation range is a transition area created? - ANS ✓Between 700ft and 2200ft AGL
What are control zones? - ANS ✓Airspace around some aerodromes that keep IFR aircraft
within controlled airspace and facilitate VFR, IFR traffic control
What is the usual elevation range for a control zone? - ANS ✓0-3000ft AGL
Can the upper elevation of a control zone vary? - ANS ✓Yes
Under what conditions can VFR traffic operate within a control zone? - ANS ✓Under VFR
weather minima or request special VFR
What is the usual radius of a control zone that is associated with a terminal control area? Can
it vary? - ANS ✓7 NM and it can vary
Does the airspace classification of a control zone depend on the classification of the
surrounding airspace (i.e. it matches it)? - ANS ✓Yes
What entity controls IFR traffic within a control zone? - ANS ✓Area control centre (ACC)
What entity controls IFR traffic within a terminal control area (TCA)? - ANS ✓Terminal
control unit (TCU)
