Area Services Flashcards
List uses for information provided by the surveillance system and presented on the Air Situation Display.
- Provide surveillance services
- Provide vectoring
- Provide Separation and maintain normal traffic flow when an aircraft experiences communication failure within the area of coverage.
- Maintain flight path monitoring of air traffic.
Would an IFR flight heading in an easterly direction below FL290 be at an odd or even level?
Odd
When operating within block levels, may a pilot operate at any of the levels within the block?
Yes
In what level band is RVSM airspace?
FL290 - FL410
What symbol in field 10a of a flight plan indicates that an aircraft has RVSM approval?
W
State four reasons a controller may use vectoring.
- To facilitate an expeditious and efficient departure flow and expedite climb to cruise level
- To prevent potential conflicts
- To establish an expeditious and efficient approach sequence
- To assist pilot navigations
When an aircraft experiences communications failure, how can surveillance systems help?
Allows a controller to provide separation and maintain normal traffic flow within the area of coverage.
In what environments may procedural or non-surveillance separation techniques be used?
Remote or oceanic airspace that lacks access to surveillance equipment.
What information must a pilot provide when they fly over a compulsory reporting position?
- Time overhead the last position
- Fly level/altitude
- Estimate for next position
Where in a flight plan is an aircraft’s navigation equipment found?
Fields 10a and 18.
What does S in field 10a of a flight plan indicate?
Standard equipment - VHF, VOR, ILS
What does a D in field 10a of a flight plan indicate?
DME
How is ADF indicated in field 10a of a flight plan?
F
How is GNSS indicated in field 10a of a flight plan?
G
What does H indicate in field 10a of a flight plan?
HF
How is INS indicated in field 10a of a flight plan?
I
What does J2J4 indicate in field 10a of a flight plan?
Datalink
How is RNAV indicated in field 10a of a flight plan?
R
What does a V indicate in field 10a of a flight plan?
VHF
What does a Z indicate in field 10a of a flight plan?
Other
What does PBN in field 18 of a flight plan indicate?
Performance based navigation
What are the two forms of datalink?
- ADS-C (Automatic Dependent Surveillance Contract)
—– The Flight Management System on board the aircraft reports position direct to ATS systems at predetermined intervals. - CPDLC (Controller Pilot Data Link Communications)
—– similar to SMS messaging
—– provides a link betwen ATC & pilots to communicate using a set of predetermined messages.
What kinds of surveillance equipment does Airservices use in the Australian FIR?
- Radar
- ADS-B (Automatic Dependent Surveillance - Broadcast)
What is radar surveillance used by ATC for?
To manage the flow of traffic into controlled aerodromes.
This allows for the most efficient use of runways.
True or False. The use of ADS-B equipment is optional for IFR flights.
FALSE.
The use of ADS-B equipment is mandated for all IFR flights.
What conditions must be met for an aircraft to be ‘identified’ on a surveillance system?
Track symbol must be correlated to the aircraft’s expected position and level must be verified using one of the below thresholds:
- Maintaining level - within 200ft of assigned
- Vacating a level - a change of 400ft or more in the anticipated direction from previously assigned level
- Passing a level on climb/descent - passed the level in the required direction by 400ft or more
- Reaching a level - within 200 ft of the assigned level for the greater of three consecutive updates or 15 seconds
Where is radar coverage found in the Australian FIR?
Areas of highest traffic density.
- The J-Curve, between Adelaide and Cairns
- Perth
- Paraburdoo
Once an aircraft has been correctly identified and verified what separation standards can be applied?
Radar separation standards of 5NM within En-Route airspace and 3NM in the TMA.
What is ADS-B?
A system in which electronic equipment onboard an aircraft automatically broadcasts the precise location of the aircraft via a digital data link.
This can be used by other aircraft and ATC to show the aircraft’s position and altitude on display screens without the need for radar.
What is considered ADS-B airspace?
Airspace at or above FL290 over the following:
- mainland Australia and Tasmania
- The sea south of and including air route B598 (Gulf of Carpentaria)
- The sea north of and including air routes L513 and Q27 (Great Australian Bight) outside radar coverage E of a line CDU-MTI
Typically, in Australian airspace, how often are aircraft required to report position/level information via ADS-C.
At 15 minute intervals.
