Coordination

Question 1

Coordination allows controllers to exchange information necessary ________

Answer 1

for the safe conduct of flight

Question 2

What are the principles of coordination?

Answer 2

Conduct coordination:

• on a point-to-point basis, whenever possible
• so that traffic coordination takes precedence over non-traffic coordination requirements
• on intercom or liaison channels; and
• on public telephone channels when intercom/liaison channels not available

Question 3

What is a heads-up?

Answer 3

A heads-up is the name given to basic coordination as detailed in NAPM. It is essentially a process whereby one ATS unit asks an adjacent ATS unit to look at a specified location for a nominated callsign and indicate acceptance of the route and level by reading back the callsign and level.

In addition, the receiving ATS unit is advised of “assigned”, “on climb”, or “on descent” to enhance the situational awareness.

Question 4

When may a heads-up be used?

Answer 4

Where it is certain that both ATC have access to the same ATS system data.

Question 5

Explain back coordination

Answer 5

Aircraft under your jurisdiction may still affect aircraft in the previous sector.

Back coordination is required to inform the previous controller of any changes that may affect their traffic.

Question 6

Explain boundary coordination

Answer 6

Traffic operating within the lateral parameters of adjoining airspace may infringe separation with aircraft operating in that sector. These aircraft must be coordinated, even though they will not enter the neighbouring sector.

Question 7

What are the readback requirements of coordination?

Answer 7

• Read back the key elements of any received coordination, clearance or instruction from another ATSO.
• ATC should also read back QNH and the words “VISUAL”, “AMENDED”, “RECLEARED” or “CANCEL CLEARANCE” in addition to the pilots-to-ATS readback requirements.

Question 8

What is included in a heads-up notification?

Answer 8

• an indication of the aircraft’s position;
• the aircraft’s callsign; and
• the coordinated level if different to the CFL.

Question 9

What are the read back requirements of a heads-up?

Answer 9

• aircraft’s callsign; and
• the CFL or coordinated level unless the standard assignable level specified in LIs or LoA is assigned.

Question 10

How should an indication of an aircraft’s position be expressed during a heads-up?

Answer 10

• relative to the position of the aircraft expressed as a cardinal point (‘SOUTH WEST, QANTAS ONE’);
• the name of the position or waypoint on, or closest to, the boundary (‘VIA APOMA, QANTAS ONE’);
• a taxi and/or departure call (‘DEPARTURE YBNA, ABC’); and
• when not identified and on climb to the CFL (‘SOUTH WEST, QANTAS ONE ON CLIMB’).

Question 11

When is full position coordination required?

Answer 11

Where controllers are operating on different systems and do not have messaging that can be verified

Question 12

In any coordination, prefix the cleared level as “___________” or “____________” or “_____________” except when the:
- Aircraft is ____________ the assigned level at the time of coordination; or
- The coordination is a taxi or departure advice

Answer 12

1. ASSIGNED
2. ON CLIMB
3. ON DESCENT
4. maintaining

Question 13

Once coordination has occurred, what must be done if changes to levels etc are requested?

Answer 13

Conduct further coordination prior to amendment of coordinated items.

Question 14

When is voice coordination required in class G airspace?

Answer 14

Voice coordination is not required, subject to NAPM defined conditions, unless there are changes within:
- 20NM of the sector boundary for identified aircraft within the same FDRG;
- 10 NM of the sector boundary for identified aircraft transiting to or from a TCU within the same FDRG; or
- five minutes of the sector boundary for:
—– non-identified aircraft; or
—– any aircraft crossing the FDRG boundary.
