Air Traffic Services Flashcards
Each PIC of an aircraft on a VFR flight shall when operating in controlled airspace, report the position of the aircraft to ATC when?
at times or reporting points required by ATC
the pilot of an aircraft operating VFR is required to contact ATS for ATC clearance when?
- prior to operating on the maneuvering area of a controlled airspace
- prior to entering class C or D airspace.
the pilot of an aircraft is required to contact ATS when? (CAR 91)
- before entering a restricted area or military operational area where ATC is the controlling authority
- before entering a general aviation area where that area requires prior notification to, approval from ATC to activate the area.
- to cancel or amend a SARTIME before expiry.
recommended that the pilot operating VFR contact ATS if what?
- on ATC service maybe use
- NOTAM or weather info required.
except when under radar control pilots must report position when?
- when over each designated compulsory reporting point and navigation aid, or if the route isn’t defined by reporting points
- prior to controlled airspace entry
what is UNICOM?
air to ground communication facility providing an information service at aerodromes with no aerodrome control or AFIS.
what is in a UNICOM? (4)
- current weather information and conditions
- basic weather information including wind direction and strength, visibility, cloud cover, temperature, QNH
- meteorological reports
- AWIB
what’s an AFRU?
a unit that provides confirmation to pilots that they’ve selected the correct aerodrome frequency, and that their aircraft radio is operating correctly. It may operate as a supplementary device to a UNICOM operating on the aerodrome frequency or it may be the sole ground communication device.
what’s an AWIB?
automated broadcast on a specified frequency at some unattended aerodromes. It relays information on meteorological and operational conditions that are obtained from automatic sensors and manual obstructions.
what information can be broadcast on AWIB? (7)
- preferred runway-in-use
- other operational information
- wind direction and strength
- visibility
- cloud cover
- temperature
- QNH or mean sea level pressure
what is TIBA?
reports and information transmitted by pilots for the information of pilots of the aircraft in the vicinity following a significant disruption to air traffic or telecommunication services.
when will TIBA be introduced?
only when necessary and as a temporary measure. If circumstances permit, an introduction if TIBA will be by NOTAM
when should pilots of aircraft initiate TIBA?
when theres complete failure of communications from ATC
what are the broadcast procedures that should be applied in designated airspace?
- need to supplement collision hazard information provided by ATS outside controlled airspace
- a temporary disruption of normal ATS.
when should a listening watch be maintained on TIBA frequent?
10 minutes before entering TIBA airspace until leaving that airspace. Aircraft taking off from an aerodrome located within the lateral limits of TIBA airspace. listening watch should start ASAP to or after takeoff.
when should broadcasts be made? (4)
- 10 minutes before entering TIBA airspace, or for a pilot taking off from an aerodrome located within the lateral limits of TIBA airspace of for as soon as appropriate prior to or after take-off
- 10 minutes prior to and cross any reporting points
- at 10-minute intervals between reporting points
- 10 minutes prior to crossing or joining the ATS route.
clearances are required by who? (3)
- all aircraft, helicopters, vehicles, equipment, and pedestrians to operate on the maneuvering area at a controlled aerodrome when ATC is in attendance
- IFR flights in Class C or D airspace
- VFR flights in Class C or D airspace
a clearance that requires a readback is not deemed to be in effect until what?
it has been read back correctly.
an ATC clearance may not be withheld except for what reasons? (3)
- traffic reasons (IFR and VFR)
- where ATC cant accommodate traffic additional to that already accepted due to limitations of equipment, procedures, environmental conditions, or other similar factors
- for non-payments of airways due only for departing aircraft to taxi onto a maneuvering area at a controlled aerodrome.
a pilot of an aircraft operating in a control area or control zone must what?
- except when maneuvering in accordance with an ACAS resolution advisory or a GPWS or TAWS alert, comply with any ATC clearance or instruction issued by the ATC unit responsible for the control area/zone.
- when a deviation from an ATC clearance or instruction is required for the safe operation of the aircraft, Notify ATC of the deviation ASAP.
a pilot of an aircraft who elects not to comply with ATC clearance or instruction must what?
notify the appropriate ATC unit of the non-compliance.
Each PIC of an aircraft on or in the vicinity of an aerodrome with an AFIS in operation shall what? (CAR 91)
- if the aircraft is equipped with a radio, maintain two-way radio comms with that service on the prescribed frequency.
- advise that service of the intended use of that aerodrome prior, taxiing, landing or taking off, or entering the circuit of the aerodrome.
Each PIC of an aircraft that’s not equipped with a radio and that’s on or in the vicinity of an aerodrome with an AFIS in operation shall advise that service of the intended use of the aerodrome prior to what?
- taxiing onto any portion of the maneuvering area
- entering the aerodrome traffic circuit at that aerodrome
A PIC of an aircraft mustn’t enter a control zone unless what?
they get ATC clearance to enter.
