Q

What are the requirements for Class B airspace, which is usually found only in areas with radar coverage where a need exists for ATC services to IFR and control VFR aircraft?

A
  • Class B is all low level controlled airspace above 12500ft ASL and up to but not including FL180 and is indicated by a hatched pattern on LO charts and a dark blue line on VFR Navigation charts (VNC)
  • IFR and VFR allowed
  • Clearnace required to enter
  • Mode C transponder

Q

Define Class C airspace

A
  • Class C is defined, controlled airspace around busy airports, described as Terminal Control Areas and their associated Control Zones
  • IFR and VFR allowed (IFR provided with traffic separation and VFR provided with traffic info upon request)
  • Clearance required to enter
  • Transponder Mode C
    **Class C reverts to Class E when ATC is closed

Q

Define Class D airspace

A

-Defined controlled airspace around kinda busy airports (Halifax) described as Terminal Control Areas and their associated Control Zones

-IFR and VFR allowed but where VFR must establish two-way communication before entering
-MAY need transponder Mode C (will say on the map or CFS)

Q

What are the 7 Class F Activity Codes?

A

S - Soaring
H - Hang gliding
A - Aerobatic
T - Flight Training

P - Parachute
F - Flight Test Area
M - Military

17
Q

What are the parameters of the restricted airspace around a forest fire?

A

-It extends from the surface of the earth up to 3000AGL
-Has a radius of 5NM
-Will be published and modified via NOTAM

18
Q

What are the characteristics of Class G airspace?

A

-Covers 99% of Canada and is uncontrolled
-No restrictions for IFR or VFR
-Extends up to Class A airspace unless another overlying airspace is indicated above it

19
Q

What are Low Level Air Routes?

A

Low level air routes are similar to airways but are Class G uncontrolled airspace. They are designated by two letters and a number, ie: AR34

20
Q

What airspaces require a transponder?

A

-All Class A, B, and C
-Class D and E MAY require one
-All Class E extending from 10000ASL up to and including 12500ASL within radar coverage

21
Q

What are types of controlled airspace?

A

-High Level Airspaces FL180 (SDA), FL230 (NDA), FL27 (ACA) and above (Class A)
-Low level airspace that is Class B, C, D, or E.
-All low level airways, which are Class E, are controlled

22
Q

What do IFR aircraft require to enter into any contolled airspace, regardless of Class?

A

A clearance

23
Q

What are the usual dimensions of a Control Zone (CZ)?

A

Extends upwards from the surface, up to and including 3000AGL (unless otherwise specified)

24
Q

What is the purpose of a Control Area Extension (CAE) and the typical dimensions of them?

A

-To provide aditional controlled airspace for IFR traffic.
-A CAE typically surrounds and overlies the core Control Zone.
-CAE typically extend upward from 2200AGL up to but not including 18000ASL, same as an airway

25
Q

In a Control Area Extension (CAE) who controls the IFR traffic?

A

The Area Control Center (ACC)

26
Q

On the map for YHZ, the control zone is noted as being 3500 (3000). Which one is ASL and which one is AGL?

A

3500 ASL (3000AGL)

27
Q

If there is no info on the map for radio contact for an aerodrome, where should you look for that info?

A

The CFS

28
Q

What are the VFR Weather minima in CONTROLLED airspace?

A
29
Q

What are the VFR weather minima in UNControlled airspace?

A
30
Q

What is Special VFR (SVFR)?

A

-Grants permission for VFR aircraft to proceed into a CZ when weather is below VFR minima (basically you admitting you kinda fucked up and are in a bit of trouble)
-You must ask ATC for it, it will not be offered
-Even in SVFR you still must:
Remain clear of cloud
Maintain visual contact with the ground
For a plane, have a min visibility of 1SM
For a heli, have a min visibility of 1/2 SM

31
Q

When and for what are you allowed to request SVFR?

A

-During the day, VFR may request SVFR to arrive or depart
-During the night, aircraft may request SVFR for arrival only
-Night VFR Heli may request SVFR to arrive or depart

32
Q

When we use the term ‘airway’ (those highways in the sky) what is that applicable to?

A

A VOR to VOR Highway/Airway
An NDB to NDB Highway/Airway
And NDB to VOR Highway/Airway

*Airways are Class E airspace and always start at 2200AGL up to FL180 IF there is no overlying Class B, C, or D airspace

33
Q

What are the dimensions of VHF/UHF and LF/MF Low Level Airways?

A
34
Q

What are T-Routes and their dimensions?

A

-Low level controlled fixed RNAV Routes
-10NM on each side of the center line
-Unlike VHF and LF Airways, they are straight and do not splay out after a certain distance

35
Q

What map shows T-Routes?

A

Only Lo-Charts
