PT1 Flashcards
Define an Air Traffic Control Clearance
Authorisation for an aircraft to proceed under conditions specified by an air traffic control unit
Define Approach Control Service
An air traffic control service for arriving or departing controlled flights
Define Visual Departure
A departure by an IFR flight when either part or all of an instrument departure procedure is not completed and the departure is executed in visual reference to terrain
What are the objectives of Air Traffic Services? (5)
Prevent collisions between aircraft
Prevent collisions between aircraft on the manoeuvring area and obstructions on that area
Expedite and maintain an orderly flow of air traffic
Provide advice and information useful for the safe and efficient conduct of flights
Notify appropriate organisations regarding aircraft in need of search and rescue aid, and assist such organisations as required
How much must an estimate change by in order for a revision message to be given to the next unit?
Area, Approach or Flight Information sector - 2 minutes
A radar sector - 3 minutes
An aerodrome control or aerodrome flight information unit - 5minutes
When can an ATC clearance be denied or withheld? (2)
For traffic reasons, when ATC cannot accommodate traffic additional to that already accepted due to traffic congestion, limitations of equipment, procedures, weather or environmental conditions, emergencies or other similar factors; or
When instructed by the General Manager Air Traffic Services
What are the elements of an ATC clearance? (7+7)
Aircraft ID as shown on the flight plan
If appropriate, notification and reason for unavailability of requested route and/or cruising level
Authorisation to operate in controlled airspace in accordance with instructions issued
Clearance limit
Route instructions
Level instructions
Any other instructions or information as required:
- departure and diversionary climb instructions
- oceanic transition
- separation or reporting instructions
- SSR code allocations
- any special instructions
- frequency change instructions
- release instructions
- delivery instructions
What is the phraseology for the unavailability of route and/or cruise level?
“(route and/or cruise level) NOT AVAILABLE DUE (reason) [ALTERNATE(S) IS/ARE (route(s) and/or level(s)) ADVISE”
Standard route clearances detail what? (3)
The ATS preferred route between aerodrome of departure and aerodrome of destination
Primary, alternate and secondary routes available
Route specified for special or restricted use
Pilots shall be informed of obstacle clearance reference whenever..? (4)
A climb or descent instruction is issued that is based on the use of enroute descent (distance) steps, VORSEC/VORTAC chart steps, Terminal Arrival Altitudes, 25 NM Minimum Sector Altitude diagram or visual terrain clearance; or
A climb or descent instruction is issued by a radar controller that is based on the use of radar terrain map; or
A descent instruction is issued that is based on the use of DME arcs; or
Where the reference on which instructions are based is changed or may not be obvious
Should aircraft on non-standard levels be afforded priority over aircraft on standard levels?
No
Departure instructions shall be issued to all IFR flights from controlled aerodromes and take the form of one or more of the following: (6)
Published instrument departure procedure i.e. SID including SID transition where applicable or other AIPNZ departure procedure
Radar SID
Visual departure (by day only)
Specified track or heading within an evaluated climb sector of an omnidirectional departure procedure
Climb above en route descent (distance) steps or VORSEC chart steps
Specified local procedure provided by ATS Policy and Standards
What is required from ATC with regard to departure and diversionary climb instructions?
Where published instrument departure procedures do not intercept the cleared route, instructions shall be
issued to clearly define how the route is to be joined.
Prior to leaving a climb sector the aircraft shall be: (5)
Established on an evaluated route contained within the radials/tracks defining the sector; or
Established on a climb above VORSEC chart steps; or
Required to set heading overhead an aid contained in the sector at the MSA or climbing above en route descent (distance) steps for an evaluated route; or
Established under radar control at or above the minimum radar terrain map level; or
Expected to be established under radar control en route, and at or above 13000ft or an approved area MSA
What are the provisos for the use of Rate of Climb separation? (7)
For rates of climb take-off, confirmation is obtained from both pilots that the specified rates of climb are acceptable and can be sustained to MSA. In all other cases, pilot readback may be taken as acceptance
An alternative method of separation can be applied in a timely manner if required
At least 2000ft exists between the aircraft at the commencement of the application
The specified rates will not allow separation to decrease below the minimum
Separation is checked at intervals of not more than 5000ft or 5 minutes, whichever is the more frequent
Forecast/observed/reported mountain wave activity or turbulence that might affect aircraft performance is not present
The aircraft are at or below FL290
