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
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 aircraft ½ mile for helicopters -working radio -clear of cloud, in sight of ground at night, only to allow the aircraft to land
CAVOKKAV-OH-KAY • No cloud below 5,000 feet, no cumulonimbus • Visibility of 6 SM or more • No precipitation, thunderstorms, shallow fog or drifting snow
EMERGENCY • Declared • Apparent • Transponder 7700 • Radio 121.5 Mhz • 243.0 Mhz
EMERGENCY • Mayday or Pan Pan 3 times • On air to ground frequency in use • Name of station addressed • Aircraft identification • Nature of distress/emergency • Intentions of PIC • Position, altitude and heading
EMERGENCY • Communication failure 7600 • Unlawful interference 7500 • If dual VHF then monitor 121.5 is suggested in AIP SAR 4.2 • Radar alerting manoeuvres RONLY NORDO
Some Types of Distress MAYDAY Urgency PAN PAN Safety Security National Security CIRVIS
ELT Emergency Locator Transmitter • SAR Search and Rescue • SARSAT & COSPAS Search and Rescue Satellites • Test ELT – first 5 minutes of hour, no more than 5 seconds • In error – call 121.5, 126.7 or HF5680khz • MANOT Missing aircraft Notice
ELT Emergency Locator Transmitter • A Automatic ejectable • AD Automatic Deployable • F Fixed • AF Automatic Fixed • AP Automatic Portable – integral antenna • P Personnel • W or S Water activated or Survival
VHF Direction Finding Service • Provides directional assistance • An aid in times of difficulty • SVFR aircraft will not be given VDF steers • Provided when requested by the pilot, or suggested by the VDF operator and accepted by the pilot
Communication Problems • Stuck mike • Two on at once • Radio failure -out of the zone -entering the zone -in the circuit • NORDO • RONLY
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: • leave the airspace • where the airspace is a control zone, by landing at the aerodrome for which the control zone is established • 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: • squawk 7600 on the transponder (if the aircraft is equipped with one) • 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 peace officer, an officer of police authority or an officer of the Canadian Forces • a person authorized to do so by the Minister
VFR Transponder Operation • 12,500’ and below – 1200 • Above 12,500’ – 1400 • Emergency – 7700 • Other codes assigned by TRSA or a tower “Squawk 5670” “Ident” “Squawk standby” • Turn to standby when re-selecting a code
Wake Turbulence -light -medium -heavy Intersecting Runways -sequential -simultaneous -intersection take-off
Flight Priority • First come, first served -Emergency -MEDEVAC -SAR -Military aircraft -VIP’s
Conversion Tables/Factors • CFS part one • AIP GEN 1-12 and 1-13 • US gal to litres 3.785 • Stat miles to naut miles 0.868 • Roughly 70 to 60 • Kilograms to pounds 2.205 • Naut miles to kilometres 1.852
