AAA Pavement & Lighting Forum 26th May 2021Major Control System Update
AAA Pavement & Lighting Forum 26th May 2021Airfield Lighting Control and Monitoring System
– Benefits of moving to ILCMS
• Real time feedback from each light individually (on/off or in fault)
• Ability to extinguish individual lights on a circuit (MOWP stages)
• Ability to set parameters for sections of Taxiways or Runways for downgrade warnings/alarms
• Integrated with Airservices INTAS system

AAA Pavement & Lighting Forum 26th May 2021Key Challenges AAA Pavement & Lighting Forum 26th May 2021
Covid-19 Impacts
Negative Impacts
- Uncertainty around Melbourne Airport Capital Plan and which
project would proceed
- FY21 pre Covid plan was ~$1B. At the end of FY21 we are
forecast to spend ~$300M
- Majority of capacity related projects were cancelled or put
on hold
- Available spend fluctuated throughout FY21
- Lockdowns
- Vic restrictions on construction sites (reduce workforce to
25%), managed to secure exemption from Chief Health
Officer due to critical nature of the works
- Aircraft operations we did have were valuable
- Parked aircraft made access to taxiways difficult
- Difficulty in bringing in construction staff from inter-state
Positive Impacts
- Improved access due to reduced traffic
- Reduced need for night works (improved safety)
AAA Pavement & Lighting Forum 26th May 2021Construction Staging
- 92 Individual Works Stages
- Most areas returned to service after each shift
AAA Pavement & Lighting Forum 26th May 2021Approvals
Airspace – Prescribed Airspace (OLS and Environmental approvals
PANSops) • Minimise impact to Natural Temperate Grassland of the
Lead time for runway closures 4-5 Months Victorian Volcanic Plain (NTGVP) – threatened ecology
• Part-13 permit for disturbance areas under the
As a leased Commonwealth airport, Melbourne Airport is
Environmental Protection and Biodiversity Conservation
subject to the Airports Act 1996 (Cth) (Airports Act) and the
Action 1999
Airports (Protection of Airspace) Regulations 1996 (Cth)
(Airports Airspace Regulations).
Part 12 of the Airports Act and the Airports Regulations
establish a framework for the designation and protection
of prescribed airspaces at, and around, airports.
- Identify works area, verify impacts, consider
mitigations
- Application submitted to Airservices (~6 Weeks)
- Application then submitted to CASA (~6 Weeks)
- Final submission to the Department -28 Days
AAA Pavement & Lighting Forum 26th May 2021What's Next AAA Pavement & Lighting Forum 26th May 2021
Follow the Green
• An ILCMS system incorporated into a ALCMS system, is Follow the Green Ready.
• What is Follow the Green?
• As the name suggests – follow the green taxiway lighting from runway to gate though intelligent routing and
guidance
• Different levels of FtG
• From basic – designated lit routes from runway to the apron area - all other lighting turned off
• Through to a fully automatic system – The ALCMS knowing the aircraft position via input from Airservices
Advanced Surface Movement Guidance and Control System (A-SMGCS), the centreline lighting illuminates
ahead of the aircraft directing the pilot to the gate, with the lighting extinguished behind the aircraft
• Benefits of FtG
• Provides one lit taxi route for pilots to follow removing multiple options at taxiway intersections
• Less chance of taking incorrect taxiways
• Reduced radio traffic
• Reduces fuel burn
