The starting point of the entire AGL Asset Lifecycle Guide. Before an asset can be maintained, inspected, tested, or eventually replaced, the organization has to answer a more basic set of questions — what AGL assets exist, what role each one performs, how important it is, who owns it, how long it should serve, and what the overall strategy is for managing it across its life.
The question this division answers — What AGL assets do we have, what role do they perform, how important are they, who owns them, how long should they serve, and what is our strategy for managing them throughout their lifecycle?
Division 01 stays strategic — it defines what the organization intends to do with its assets and why. The detailed data structure moves into Division 02, and the detailed criticality/risk methodology moves into Division 03.
Establishes the strategic foundation for every AGL asset before procurement, installation, operation, and maintenance.
Runway lighting, taxiway lighting, approach lighting, PAPI, airfield signage, CCRs, isolation transformers, primary/secondary cables, connectors, base cans, cable ducts, handholes, foundations, ALCMS/control systems, and associated electrical infrastructure — the recommended flagship asset series to populate first.
The process of determining what physical or functional items should be treated as managed AGL assets. Every significant asset should have a unique identity.
A runway edge light should not simply be recorded as "Runway Light." Instead:
With associated information: runway (RWY 09/27), location/chainage, asset type, manufacturer, model, serial number, installation date, commissioning date, criticality, condition, and maintenance history.
Establishes a standardized structure for grouping assets.
Level 2 examples: Runway Lighting, Taxiway Lighting, Approach Lighting, PAPI, Airfield Signage, CCR System, ALCMS, Electrical Distribution.
Level 3 examples: Runway Edge Light, Runway Threshold Light, Taxiway Edge Light, Isolation Transformer, CCR, Primary Cable, Secondary Cable.
Level 4 example:
Defines the relationship between the airport, system, subsystem, equipment, and component.
Airport → AGL System → Runway Lighting System → CCR System → CCR No. 01 → Power module → Control module → Output transformer.
This hierarchy becomes particularly important once the asset register is connected to CMMS/EAM, digital work orders, maintenance history, inspection records, and testing records — the core of Division 21 (Digital Asset Management).
Creates a standardized identifier that communicates information about the asset. A coding structure may contain: Airport / System / Asset Class / Location / Sequential Number.
CCU = Airport · RWY = Runway · EDG = Runway Edge Light · 09 = runway/location reference · 001 = sequential asset number. The exact coding convention should be standardized at organizational level.
Note: EDG is used rather than REL for the runway edge light class code. REL is reserved in FAA Runway Status Light (RWSL) terminology for Runway Entrance Lights — a distinct in-pavement system — so it should not be reused for edge lighting to avoid ambiguity.
The formal assignment of unique numbers to individual assets. Each asset number should be unique, never duplicated, traceable, and permanently associated with the asset, used consistently across maintenance, inspection, testing, failure, and replacement records.
The numbering system should remain stable even when the asset changes maintenance personnel, condition, or ownership.
The asset register is the central controlled inventory of AGL assets. Detailed structure and data governance move into Division 02 (Asset Register & Data Management); this topic sets the minimum baseline.
Every asset should have clearly defined ownership and accountability.
Asset Owner: Airport/AGL Department · Operational Responsibility: AGL Operations · Maintenance Responsibility: AGL Maintenance Team · Technical Responsibility: Electrical/AGL Engineering · Testing Responsibility: Authorized Testing Team · Replacement Approval: Asset/Engineering Management.
Principle: every asset must have an accountable owner.
Determines how important an asset is to airport operations, safety, and regulatory compliance. Detailed methodology moves into Division 03 (Asset Criticality & Risk Assessment).
Measures the effect of asset failure on airport operations.
Measures the consequence of failure on aviation safety. A safety-critical asset requires particularly strong control over inspection, testing, maintenance, condition monitoring, failure response, documentation, and change management.
The exact classification should be established through the airport's approved risk methodology, rather than assuming every asset carries the same criticality.
Considers the consequences of an asset failing to meet applicable aviation or engineering requirements. Relevant compliance frameworks are the standards and regulatory requirements applicable to the airport and asset.
The master asset record specifically includes Related Standards as a field.
Each asset should have a defined strategy from acquisition to disposal.
Aligns asset decisions with airport requirements.
"Keep equipment running." It should be: "Deliver the required AGL performance safely, reliably, compliantly, and economically throughout the asset lifecycle."
Establishes the future requirements of the AGL asset portfolio, across suitable short-term, medium-term, and long-term planning horizons.
Looks at all AGL assets together, rather than considering one asset in isolation. Instead of asking "Should CCR-01 be replaced?" the organization should ask: "What is the condition, reliability, criticality, and remaining life of the entire CCR portfolio?"
Determines future investment requirements.
Connects forward to Division 12 (Asset Lifecycle Cost Management), including budget planning and capital-versus-maintenance decisions.
The central strategic activity of Division 01.
This connects Division 01 with Asset Health Monitoring, Reliability Engineering, Lifecycle Cost Management, Refurbishment, Obsolescence Management, and Replacement Planning.
Establishes the organization's overall commitment to managing AGL assets throughout their lifecycle.
It should establish management direction, rather than becoming a detailed maintenance procedure.
Converts the policy and strategic objectives into an actionable programme.

The mandatory outputs of Division 01.
Division 01 should remain strategic. It defines what the organization intends to do with its assets and why — not how to record the data, and not how to score the risk.
The detailed data structure moves into Division 02 — Asset Register & Data Management, while the detailed criticality/risk methodology moves into Division 03 — Asset Criticality & Risk Assessment. These functions are deliberately kept separate.
This gives the AGL Asset Lifecycle Guide a clean hierarchy — consistent with its role as the strategic layer connecting the Design, Inspection, Testing & Commissioning, Maintenance, and Failure Database functions.
Quick answers about AGL asset planning, identification, coding, registers, criticality and lifecycle strategy.
Division 01 is the starting point of the AGL Asset Lifecycle Guide. It covers 20 strategic topics (PLN-01 to PLN-20) including asset identification, classification, hierarchy, coding, the asset register, ownership, criticality assessment, lifecycle strategy, capital planning, and the asset management policy and plan. It defines what an organization intends to do with its Airfield Ground Lighting (AGL) assets and why.
AGL asset planning establishes the strategic foundation for every AGL asset before procurement, installation, operation and maintenance. It matters because decisions made at this stage, such as how assets are identified, owned, prioritized and eventually replaced, shape safety, reliability, availability, regulatory compliance and lifecycle cost for the whole life of the system.
Every significant AGL asset should have a unique identity, recorded with its name, type, description, system, subsystem, location, manufacturer, model, serial number, installation date and commissioning date. Classification then groups assets in a standard structure: airport AGL system, subsystem (such as runway lighting, taxiway lighting, approach lighting, PAPI, signage, CCR system, ALCMS), asset class, and individual asset. This supports maintenance planning, criticality analysis, failure analysis, cost analysis and replacement planning.
Asset coding creates a standardized identifier that communicates information about the asset, typically combining airport, system, asset class, location and a sequential number. For example, CCU-RWY-EDG-09-001 identifies a runway edge light at location 09, sequence 001. A good coding system is unique, consistent, permanent, scalable, human-readable, machine-readable, compatible with CMMS/EAM software, linked to physical asset tags and controlled through revision management.
An AGL asset register is the central, controlled inventory of AGL assets. It typically holds the asset ID, type, description, manufacturer, model, serial number, location, installation and commissioning dates, expected service life, warranty, owner, criticality, condition and health index, maintenance, inspection, testing and failure history, lifecycle cost, replacement forecast, disposal status, related documents and revision history.
Criticality assessment determines how important an asset is to airport operations, safety and regulatory compliance. It considers safety impact, operational impact, regulatory impact, failure consequence, probability of failure, availability of redundancy, restoration time, passenger and flight impact, maintenance complexity and replacement lead time. Division 01 introduces the concept, while the detailed methodology is covered in Division 03 — Asset Criticality & Risk Assessment.
Operational criticality measures the effect of an asset failure on airport operations, for example a CCR supplying a critical circuit. Safety criticality measures the consequence of failure on aviation safety, such as PAPI or approach lighting equipment. Regulatory criticality considers the consequence of an asset failing to meet applicable aviation or engineering standards, inspection requirements and acceptance criteria.
Each asset should have a defined strategy from acquisition to disposal. The lifecycle stages covered are acquisition, installation, commissioning, operation, maintenance, health monitoring, repair, refurbishment, upgrade, replacement, decommissioning and disposal. Lifecycle planning weighs condition, criticality, reliability, obsolescence and lifecycle cost to decide whether an asset should be repaired, refurbished, upgraded, replaced or decommissioned.
The asset management policy sets the organization's overall commitment to managing AGL assets across their lifecycle, including principles, responsibilities, safety and compliance commitments, risk-based decision making and governance. It is management direction, not a detailed maintenance procedure. The asset management plan converts that policy and the strategic objectives into an actionable programme covering critical assets, risks, maintenance, inspection and testing strategies, replacement forecasts, capital requirements, resources, KPIs and review frequency.
Division 01 stays strategic. Division 02 — Asset Register & Data Management holds the detailed data structure, and Division 03 — Asset Criticality & Risk Assessment holds the detailed criticality and risk methodology. After these, Division 04 onward covers design, procurement, installation, commissioning, operation, maintenance, monitoring, optimization, replacement and disposal.
