Approvals for Ground Runs
Aircraft maintenance organisations must obtain approval to conduct
an aircraft ground run activity.
For all sites, initial approval must be obtained from the Melbourne
Airport Senior Airside Safety Officer (Car 2) on 0418 335 985.
After initial approval, the process to be followed is:
• The maintenance organisation is to contact Air Traffic
Control to request permission to conduct an engine ground run
• Air Traffic Control (ATC) will then liaise with the Senior
Airside Safety Officer.
• The Senior Airside Safety Officer will then advise whether
the ground run is approved at the requested location and time
For sites 2 and 3 these additional procedures must be followed:
• The maintenance organisation must contact ATC when the
aircraft is ready to be positioned
• ATC will confirm with the Senior Airside Safety Officer
that he/ she has approved the ground run
• ATC will direct the aircraft to the site nominated by
the Senior Airside Safety Officer
• The Senior Airside Safety Officer will attend the location
to give final approval for the ground run to start under the agreed
conditions
Cross bleed engine starts
Cross bleed engine starts may only be conducted under the following
conditions:
• Airline/Pilot must gain approval from Senior Airside
Safety Officer and ATC prior to commencing the engine start
• No aircraft engine is to be run above idle power until
the aircraft is positioned at the crossbleed approved Tow Bar
Disconnect Point
Locations for Ground Run Activities
Four sites are available for ground running activities as follows:
Site 1: Terminal and Freight Apron Areas
Site 2: Taxiway Bravo Run-up Bay
Site 3: Taxiway Kilo Run-up Bay
Site 4: Airline Maintenance Base Aprons
SITE 1 - Terminal and Freight Apron areas
Aircraft engine ground running operations may be conducted at
any time on the apron around the passenger and freight terminal
buildings (refer to Appendix 1) provided:
• Power settings are limited to ground idle
• Not more than one engine is run at a time
• Engine ground run durations are limited to 30 minutes
for any one event
• Maintenance organisations have approval from the Senior
Airside Safety Officer prior to commencing any engine ground run.
Due consideration must be given to minimizing the noise and jet
blast from such operations on the adjoining apron and taxiway
areas.
SITE 2 – Taxiway Bravo Run-up Bay
Aircraft engine ground running operations may be conducted at
any time in Taxiway Bravo Run-up Bay (refer to Appendix 1) with
power settings and run duration at the discretion of the maintenance
organisation concerned, subject to the following conditions:
• All engine ground runs are at the discretion of ATC
• Aircraft travelling under tow to and from this location
must be escorted across Runway 27 and to the site by an authorised
Airside Safety Officer
• During engine ground runs involving aircraft facing north,
aircraft are to be positioned as far north as possible (but not
outside the parking limit area)
• During engine ground runs involving aircraft facing south,
aircraft are to be positioned as far south as possible (but not
outside the parking limit area)
• Maintenance organisations must have approval from the
Senior Airside Safety Officer prior to commencing the engine run
SITE 3 – Taxiway Kilo Run-up Bay
Aircraft engine ground run operations at Taxiway Kilo Run-up
Bay (refer to Appendix 1) may be conducted subject to the following
conditions:
• All engine ground runs are at the discretion of ATC
• During engine ground runs involving aircraft facing north,
aircraft are to be positioned as far north as possible (but not
outside the parking limit area)
• During engine ground runs involving aircraft facing south,
aircraft are to be positioned as far south as possible (but not
outside the parking limit area)
• Maintenance organisations must have approval from the
Senior Airside Safety Officer prior to commencing the engine run
• Between 2300hrs and 0500hrs (local time) the following
conditions will apply
(i) power settings not above ground idle
(ii) maximum duration 20 minutes only
SITE 4 - Airline Maintenance Base Aprons
Aircraft engine ground run operations may be conducted on the
airline maintenance base. The engine ground run duration is at
the discretion of the maintenance organisation and subject to
the following conditions:
• Power setting limited to ground idle
• Not more than one engine is run at a time
• Aircraft do not exceed apron strength limitations
• Aircraft headings where jet blast and fumes would adversely
impact adjacent facilities must be avoided
• Maintenance organisations must have approval from the
Senior Airside Safety Officer prior to commencing the engine run
• Between 2300hrs and 0500hrs (local time) the following
condition will apply
(i) maximum duration of 20 minutes only
Recording of details
Details of all engine ground runs shall be recorded by the maintenance
organisation. These records must include:
• The date of the run ie. 26 November 2008
• The type of aircraft and its registration ie. A333 VH-ABC
• The site at which the run was conducted ie. Site 1, 2,
3 or 4
• The aircraft heading in magnetic bearing ie. 090
• The number of engines being run ie. 1, 2, 3, 4
• The time each run commenced and finished ie. 0500-0515hrs
• The power setting used for each run ie. Idle, medium,
high
A copy of the records must be faxed to the Airside Operations
Supervisor on 9297 1041 the following working day.
Requirements of Maintenance Organisations
• To ensure that appropriate maintenance personnel are
aware of the ground running sites, and of the conditions relating
to their use, the maintenance organisation must take such steps
as necessary to publish details of the sites and procedures in
whatever form of internal documentation is most appropriate.
A copy of all documentation must be supplied to the Airside Standards
Supervisor.
• Maintenance organisations must ensure the person towing
an aircraft to a ground running location is a holder of a current
Airside Driver Authority Level 3 and the vehicle has a current
Authority for Airside Use (Airside Vehicle Permit).
Safety precautions
• Anti-collision beacons must be switched on throughout
the engine ground run
• Aircraft maintenance organisations must ensure that all
personnel, equipment and cargo is well clear of the rear of the
aircraft during an engine ground run
• A supervisor must be appointed over the engine ground
run to ensure the safety of the operation and all airside users
in the vicinity. The engine ground run must be stopped immediately
if a dangerous situation arises
• To improve visibility for airside drivers, all ground
service equipment must be moved well away from the aircraft during
the operation
• Before commencement of aircraft ground run activity at
Site 1 (Terminal and Freight Apron areas), warning signs must
be placed on the edge of the Apron Service Road directly behind
each aircraft wing tip to warn other apron users that aircraft
ground run activity is in progress.
The signs should state, ‘Caution: Engine Ground Run in
Progress’.
Engine ground run signs must be removed immediately following
the end of the aircraft ground run activity to signal to apron
users that it is safe to pass behind the aircraft.
