Q

What are the principles of coordination?

A

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

Q

What is a heads-up?

A

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.

Q

Explain back coordination

A

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.

Q

Explain boundary coordination

A

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.

Q

What are the readback requirements of coordination?

A
  • 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.

Q

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

A
  • 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’).

Q

When is voice coordination required in class G airspace?

A

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.
