Answer 1

15 Minutes

Question 2

Heads-up Coord?

Answer 2

20 NM to other sectors in CTA.
30 NM to approach sectors in CTA.

Question 3

Boundary Coord?

Answer 3

Half the applicable radar standard (2.5NM)

Question 4

Answer 4

No vertical changes, lateral changes within 45 degrees.

Question 5

Voiceless Coord?

Answer 5

To or from Class G:
No coord required provided no changes within:
Another sector 20NM
TCU 10NM

CTA to CTA between sectors as specified in LI/LOA. No changes within 20 NM.

Question 6

HUM/CB TMA

Answer 6

A085 and Below - G to C (voiceless coord)
A090-A100 C to C en route control (surveillance) to approach (surveillance)
No coordination required from ENR to CB TCU provided aircraft is assigned lowest assignable level of FL110 (subject to QNH)

Question 7

HUM/YAS

Answer 7

A085 and below- G to G (voiceless coordination)

Question 8

HUM/GLB
Heads-up in one direction.

Answer 8

No coord required when ident, except when requesting changes within 20 NM.

Slow climbers may need to be coordinated on taxi.
e.g WG-SYD via GLB may not be ident prior to 20NM.

Question 9

HUM/SNO

Answer 9

At FL180 and below - Class G/C/E to Class G (voiceless coord)
Above FL180 - Class A to Class E (en route control (surveillance) to en route control (surveillance)).

Question 10

HUM/TEM

Answer 10

FL180 and below - Class G to Class G (voiceless)
FL180 to FL245 - Class E to Class E (en route control (surveillance) to en route control (surveillance)).

Question 11

HUM/MLE

Answer 11

FL180 and below - G to G (voiceless)
FL180 to FL245 - E to E (en route control (surveillance) to en route control (surveillance)).

Question 12

HUM/OVN

Answer 12

A085 and Below - G to G(voiceless)
Above A085 to FL125 in J curve - Class E to E (en route control (surveillance) to en route control (surveillance)).
Above FL125 in J curve - Class A/C to Class A/C (en route control (surveillance) to en route control (surveillance)).

Question 13

HUM/ AY TWR

Answer 13

Arriving A090 and above - sequence. (en route control (Procedural or surveillance) to approach (procedural).
Arriving A085 and below - 10 minutes prior to lateral boundary.

Question 14

HUM/BLA

Answer 14

No voice coordination required, so as long as aircraft handed off the standard assignable level with voiceless coord between vertically adjoining sectors.

The transfer is with:
No vert restrictions in the expected direction of the aircraft’s vertical manoeuvre; and
no lateral restrictions within 45 degrees of the nominal forward track.

Question 15

OVN/ELW
Heads-up in one direction

Answer 15

Aircraft taxiing at AY that will enter ELW airspace do not need to be coordinated provided that they remain south of the WG-ELW line and are not assigned a level in ELW’s airspace until after identification. If you wish to assign a level above A080 at the “next”call, it must be pre-coordinated with ELW sector.

The exception is except when aircraft are requesting changes to route or level within 20NM OR are not identified.

Coordination is required on all flights west of a line WG-ELW

No coordination is required when aircraft are identified and tracking between sectors as indicated, except when requesting changes to route or level within 20 NM of the receiving sector.

Question 16

OVN to ELW

Answer 16

Aircraft tracking on or south of a line WG-ELW within 100 DME ML, excluding aircraft departing YMAY.
For identified aircraft, coordination is not required before assigning a level in ELW sector airspace.

Question 17

OVN/BLA

Answer 17

No voice coordination required so long as aircraft handed off assigned the standard assignable level with voiceless coord between vertically adjoining sectors.

The transfer is with:
a) no vertical restrictions in the expected direction of the aircraft’s vertical manoeuvre; and
no lateral restrictions within 45 degrees of the nominal forward track.

Question 18

OVN/AY

Answer 18

Arriving A090 and above - Sequence. (en route control (procedural or surveillance) to approach(procedural)).

Arriving A085 and below - 10 minutes prior to lateral boundary

Question 19

OVN/HUM

Answer 19

AY departures boundary coordination OVN/HUM.
AY departures into OVN airspace may require boundary coordination with HUM when climbing to levels above A085.

Question 20

OVN/SNO

Answer 20

120.75
at FL180 and below - G to G (voiceless)
FL180 to FL245 - E to E (en route control (surveillance) to en route control (surveillance)).

124.0
ESL Active - G to G below R358 - (voiceless).
ESL de-active - G to G FL180 and below. (voiceless)

Class E to Class E A085-FL125 between 80-90NM Melbourne (en route control (surveillance) to en route control (surveillance)).

Class C to Class C FL125-FL180 between 80-90NM Melbourne
(i.e aircraft tracking south/east between 80 and 90 NM Melbourne.
(en route control (surveillance) to en route control (surveillance)).

Question 21

OVN/ESL APP

Answer 21

When coordinating aircraft that will enter R358 to ESL APP manage in accordance with Approach surveillance parameters. En route control(surveillance) to approach (surveillance).

You are required to coordinate a taxi call when the departure aerodrome is less than 50NM from the boundary, otherwise coordinate the destination, route, level and code prior to 5 minutes or 30 NM from the boundary.

Verbal handoffs shall occur prior to 10 NM from the boundary for aircraft in Class C or E airspace.

Question 22

OVN/YWE-LOD

Answer 22

Dookie Panhandle - Coordination requirements dependant on airspace category as boundary could be Class C, E, or G.

Question 23

OVN/MLE

Answer 23

At or below FL180 - Class G to G (voiceless)
Above FL180 - Class E to E (en route control (surveillance) to en route control (surveillance)).

Question 24

DOK/ELW

Answer 24

No coordination required for aircraft climbing or descending to vertical boundary.
Consider coordinating a clearance when the aircraft is departing MNG for the west. to minimise frequency transfers.

Question 25

DOK/ML TMA

Answer 25

No coordination required to ML TMA, so long as the aircraft is identified and CFL does not change within 10 NMM of the boundary (voiceless).
Frequency transfer at A045 and below 135.7. (ML Centre)
Above A045 to 132.0 (ML APP East)

Question 26

Answer 26

Internal frequency transfer only

Question 27

Answer 27

Class G procedures (voiceless)
