Radio Communication and Procedures pt 2

Control Zones

Designated airspace around certain aerodromes to facilitate the control of VFR and IFR traffic

Usually a 5 NM radius, 3,000’ AGL VFR weather limits are higher SVFR may be requested in some zones Most zones designated as class D

Obstacle Clearance Circle

Displaced Threshold

Control Zone in a Terminal Area is

normally 7nm

radius

VFR Weather Minima

SVFR - Special VFR

Authorization obtained from the appropriate ATC unit allows you to fly:-within a control zone,-in IFR weather conditions,-without an IFR clearance-has to be requested by the pilot

1 mile for aircraft½ mile for helicopters

-working radio-clear of cloud, in sight of ground

at night, only to allow the aircraft to land

Communication Failures(602.138)

Where there is a two-way radio communication failure between the ATC unit and a VFR aircraft while operating in Class B, C, or D airspace, the PIC shall:

a) leave the airspace

i) where the airspace is a control zone, by landing at the aerodrome for which the control zone is established

ii) in any other case, by the shortest route

Communication Failures(602.138)

Where there is a two-way radio communication failure between the ATC unit and a VFR aircraft while operating in Class B, C, or D airspace, the PIC shall:

b) squawk 7600 on the transponder (if the aircraft is equipped with one)

c) inform ATC (as soon as possible) of the actions taken

Emergency Radio Capability(602.143)

No person shall operate an aircraft equipped with two-way VFR radio

communication equipment unless it is capable of providing

communication on VHF frequency 121.50 MHz.

Interception Signals(602.114)

No person shall give an interception signal or an instruction to land except:

a) a peace officer, an officer of police authority or an officer of the Canadian Forces

b) a person authorized to do so by the Minister
