Define Prohibited Area
An airspace of defined dimensions, above the land areas or
territorial waters of a State, within which the flight of aircraft is prohibited.
Designation is appropriate only for reasons of military necessity.
Define Restricted Area
An airspace of defined dimensions, above the land areas or
territorial waters of a State, within which the flight of aircraft is restricted in accordance with certain specified conditions.
Note: This designation is used when necessary in the interests of public safety or the protection of the environment.
Define Danger Area
An airspace of defined dimensions, above the land areas or territorial waters of a State, within which activities of potential danger to aircraft may exist.
In what classes of airspace is a separation service provided to IFR aircraft?
A, C, D, E
What determines the size of a sector?
The volume of traffic, availability of surveillance, type of flying activities
What Classes of airspace would a Tower administer and what determines the class?
C and D determined by the type of flying activity that takes place at the aerodrome
Which of the following aircraft has priority over the other?
a. Mercy Flight
b. Aircraft carrying a Head of State?
Mercy flight
Which of the following has priority over the other?
a. An aircraft subject to unlawful interference
b. A multi-engine aircraft with one engine failed
An aircraft subject to unlawful interference
Which of the following has priority over the other?
a. An aircraft involved in SAR operations
b. An aircraft suffering radio failure
An aircraft suffering radio failure
Which of the following has priority over the other?
a. A landing aircraft
b. A departing aircraft
Landing aircraft
Which of the following has priority over the other?
a. An aircraft taking off
b. A taxiing aircraft
Aircraft taking off
Which of the following has priority over the other?
a. An aircraft suffering radio failure
b. A multiengine aircraft with one aircraft shut down but not subject to a SAR phase
A multiengine aircraft with one aircraft
shut down but not subject to a SAR phase
What is the list of priority for aircraft?
- Aircraft in an emergency, including being subjected to unlawful interference
- Multi engine aircraft which has lost an engine and has not been subject to SAR
- An aircraft which has suffered radio comms failure
- Aircraft participating in SAR, MEDEVAC, or FFR (fire and flood relief)
- Aircraft operating under police callsign “POLAIR RED” or “FEDPOL RED” engaged in operations where life is at risk
- Aircraft engaged in personal transport of Heads of State or of Government, or other selected dignitaries on official visit, or personal transport of Governor General or Prime Minister of Australia
- State aircraft special requirements flights where clearance has been arranged (military usually)
In what classes of airspace do VFR aircraft require an airways clearance allowing them to operate?
C and D
Which aircraft are allowed to operate without a radio and in which classes of airspace?
VFR in Class G except for operations above 5000 FT AMSL and at aerodromes where carriage and use of radio is required
What have control area steps been designed to accommodate with regard to aircraft flight profiles?
Ascent and descent profiles
What class of airspace is uncontrolled?
Class G
Under what circumstances may an aircraft communicate on frequency other than that for the airspace in which they are operating?
a) In certain aspects of the SAR alerting services
b) When significant operational advantage will be gained and workload, communications and equipment capabilities permit the responsible controller to take such action as is necessary to preserve separation
Which key areas of responsibility form the primary purpose of the National Coordination Centre (NCC)?
- Airspace management
- Aeronautical Information Management
- Business Continuity and Reporting
- NCC Met
What are the three steps of transfer of responsibility?
- Prior coordination: ATC must tell next ATC of the condition of the aircraft as it crosses the boundary (e.g. its flight level)
- Hand-off jurisdiction: ATC passes the flight plan to the next ATC
- Transfer the aircraft to next controller’s frequency
What is an Off Air Route?
These allow aircraft to operate on routes that provide the fuel savings of favourable winds.
What is a User Preferred Route?
A plan produced by airlines to capitalise on best commercial operating model. Takes into account the flight characteristics of each aircraft, weather, time, cost, etc
What is a Flextrack, and who issues them?
An optimised track published by air navigation service provider and available to all users for a specific period of time. These take into account favourable winds.
Issued by Trackmaster at NCC, through dissemination of a Track Definition Message
What information does a Track Definition Message contain?
In reference to a Flextrack:
Track identifier
Validity period
