7. Control Of Ground Traffic

Question 1

Considerations for taxiing AC? (3)

Answer 1

• to follow the correct taxi routes;
• to avoid collision with other aircraft or objects
• to minimize the potential for the aircraft inadvertently entering an active runway.

Question 2

Where should standard taxi routes be published?

Answer 2

AIP

Question 3

If Taxi routes have not been published what should be used?

Answer 3

• Described by use of taxiway and runway designators.
• Other relevant information, such as an aircraft to follow or give way to

Question 4

Taxi Clearance limits

Answer 4

When a taxi clearance contains a clearance limit beyond a runway, it shall contain an explicit clearance to cross or an instruction to hold short of that runway.

Question 5

Condense
Taxiing on Runway in Use

Answer 5

For the purpose of expediting air traffic,
aircraft may be permitted to taxi on the
runway-in-use, provided no delay or risk to
other aircraft will result.

Where control of taxiing aircraft is provided by a
ground controller and the control of runway
operations by an aerodrome controller, the use
of a runway by taxiing aircraft shall be
coordinated with and approved by the
aerodrome controller.

Communication with the aircraft concerned
should be transferred from the ground
controller to the aerodrome controller prior to
the aircraft entering the runway.
If the control tower is unable to determine,
either visually or via an ATS surveillance system
that a vacating or crossing aircraft has cleared
the runway, the aircraft shall be requested to
report when it has vacated the runway.
The report shall be made when the entire
aircraft is beyond the relevant runway-holding
position.

Question 6

Use of RWY holding positions 1

Answer 6

Except as provided in the next slide or as prescribed
by the appropriate ATS authority, aircraft shall not
be held closer to the runway-in-use than at a
runway-holding position (holding point).

Question 7

Use of RWY holding positions 2

Answer 7

Aircraft shall not be permitted to line up and hold on
the approach end of a runway-in-use whenever
another aircraft is effecting a landing, until the landing aircraft has passed the point of intended holding.

Question 8

Condense

Helicopter taxiing operations

Answer 8

Instructions which require small aircraft or
helicopters to taxi in close proximity to taxiing
helicopters should be avoided and consideration should be given to the effect of turbulence from taxiing helicopters on arriving and departing light aircraft.

A frequency change should not be issued to single- pilot helicopters hovering or air-taxiing. Whenever possible, control instructions from the next ATS unit should be relayed as necessary until the pilot is able to change frequency.

Question 9

Condense

Entry to the manoeuvring area

Answer 9

The movement of pedestrians or vehicles on the
maneuvering area shall be subject to authorization by the aerodrome control tower. Persons, including
drivers of all vehicles, shall be required to obtain
authorization from the aerodrome control tower
before entry to the maneuvering area.
Despite such an authorisation, entry to a runway or
runway strip or change in the operation authorized
shall be subject to a further specific authorization by
the aerodrome control tower.

Question 10

Condense

Priority on the Manoeuvring Area

Answer 10

All vehicles and pedestrians shall give way to
aircraft which are landing, taxiing or taking off,
except that emergency vehicles proceeding to
the assistance of an aircraft in distress shall be
afforded priority over all other surface
movement traffic.
In the latter case, all movement of surface
traffic should, to the extent practicable, be
halted until it is determined that the progress of
the emergency vehicles will not be impeded.

When an aircraft is landing or taking off, vehicles shall not be permitted to hold closer to the runway-in-use than:
- at a taxiway/runway intersection — at a runway holding position
- at a location other than a taxiway/runway intersection — at a distance equal to the separation distance of the runway-holding position.

Question 11

What is free ranging?

Answer 11

At some units certain nominated and suitably qualified personnel may be able to ‘free-range’. (e.g. OPS, RFFS, Security, etc.)
Personnel will monitor the active frequency and adjust their position on the manoevring area so as to not come into conflict with operations.
This may be withdrawn when conditions necessitate.
