ALCMS Resilience Audit, AGL Inspections

TM3 Airports is an experienced AGLCMS consultancy. We provide airports with AGLCMS and AGL Resilience Audits.

ALCMS Resilience Summary

1. Compliance with applicable standards
2. Operational Test Results
3. Equipment Review – Status, Equipment Type, Modular Construction, Future Proofing
4. Scalability – Review against airports current / future planning.
5. Ease of Modification – Specific Contractor, manufacturer
6. Maintenance and Response Contracts – Areas covered by contract, Performance of Contractor, KPI’s monitored by the airport, downtime and causes

What would be the activities we would do on site?

1. 1: System Review – Look at the AGLCMS installation
2. 2: CCR Substation inspections; list i.e. panels, distribution boards.
3. Review system operation performance, back indication time, alarm indication.
4. If installed look at ILCMS performance regards switching and back indication and alarm detection.
5. Look at maintenance Procedures and practices

ALCMS Resilience Audit

Resilience is defined as the ability of a system to continue with its functionality despite excessive stresses which can cause disruptions. Being resilient is important because no matter how well a system is engineered, reality will sooner or later conspire to disrupt the system. Latent defects in software or hardware will eventually cause the system to fail to correctly perform a required function or cause it to fail to meet one or more of its quality requirements (e.g., availability, capacity, interoperability, performance, reliability, robustness, safety, security, and usability).

Due to these inevitable disruptions, availability and reliability of equipment are in themselves insufficient to guarantee trouble free operation and a system needs to be resilient.

TM3 Airports Ltd are independent Airfield Lighting & Control System engineers based in Manchester, Bangkok, and Hanoi. TM3 Airports provides specialist airfield lighting system consultancy and project management services to international & regional airports, airfield main contractors, airfield consultants, pavement companies and airfield designers.

Our airside electrical resilience audit looks at the arrangements in the following areas:-

• Review of airfield lighting installation including interleaving, substation layout and CCR utilisation, protection against fire and unauthorised access. Identifying points of failure
• Review of ALCMS Installation including control stations, monitoring stations, identify points of failure, system redundancy and resilience.
• Supply diversity and resilience including primary and secondary supplies.
• Compliance with current International and National standards
• Equipment status, type, construction, current condition, age, and future proofing.
• Scalability including the equipment’s ability to meet the future expansion plans of the airfield.
• System operation including response time for back indication and alarm signals.
• Ease of system modification, who makes the changes either manufacturer or nominated contractor.
• Maintenance procedures and training regime for system operators and engineers, maintenance and response contracts including Service Level Agreements.

Based upon the depth of report required the audit can also be extended to an Individual Lamp Control and Monitoring System, where installed, including system performance and response times for back indication and alarm reporting.

The output of the audit is to prepare all of the observations, conclusions and recommendations into a Final Audit Report.

The draft of the Final Report will be forwarded to the client for review purposes. Agreed comments and statements will be incorporated into the Final Report.

The methodology for conducting the audit is as shown in the diagram below:
