What is technology modernization?

A planned, phased move of a system onto current technology — reviewed, trialled, migrated step by step and embedded in procedures.

The Fact Asset lifecycle

Technology modernization is a planned programme that moves a system onto current technology, such as LED fixtures, networked control and monitoring, or digital asset data. It starts with a review of the current systems and a target architecture, tested through a trial before the programme is committed.

The migration is phased so the airfield stays lit, and each phase is commissioned and proved before the next. Procedures, training and records are updated and the legacy equipment is retired. A poor modernization means mixed systems, skill gaps and lost availability.

  1. Review. Understand the current systems, their obsolescence and gaps, and future needs.
  2. Target. Set the target architecture, the roadmap and the business case.
  3. Trial. Evaluate options, pilot on site and compare lifecycle cost.
  4. Phase. Plan the migration, manage old and new equipment running together, and plan the outages.
  5. Migrate. Install by phase, commission each phase and prove it before the next.
  6. Embed. Update procedures, training, records and spares, and retire the legacy equipment.
Technology modernization

A programme-level shift of a system to current technology, usually across many assets and in phases.

Upgrade

A targeted improvement to an asset or part of a system, which may be one step within a modernization.

MeaningPlanned, phased move of a system or programme of assets to current technology
Starts fromA review showing obsolescence, support gaps or needs the legacy system cannot meet
Typical examplesLED fixtures, networked control and monitoring, digital asset data
Key checksCompatibility during mixed running, availability, skills, data and cybersecurity
ProofPilot results, then commissioning and acceptance of each phase, with flight inspection where the regulator requires it
ReferenceManufacturer instructions; ICAO Annex 14 Vol. I; ICAO Doc 9137 Part 9
Schematic — simplified for clarity. Technology choices, phasing, approvals, notification, test criteria and acceptance are set by the aerodrome’s procedures, the regulator, the manufacturer and the applicable standards.

Frequently Asked Questions

Q1What is technology modernization in airfield ground lighting?

A planned programme that moves an AGL system, or a significant part of it, onto current technology, for example from older lamp-based fixtures to LED, from relay-based control to networked control and monitoring, or from manual records to digital asset data. It is broader than a single upgrade and is usually done in phases.

Q2How is technology modernization different from an upgrade?

An upgrade is a targeted improvement to an asset or part of a system. Technology modernization is a programme-level shift in the technology or architecture of the system, often covering many assets, several upgrades and changes to procedures, skills and records. An upgrade can be one step within a modernization programme.

Q3Why is modernization usually done in phases?

The airfield must keep its required lighting available throughout. Phasing limits the outages and the risk at any one time, and lets each phase be proved before the next begins. During the programme old and new equipment may run side by side, so compatibility on shared circuits, regulators and control systems must be managed.

Q4Why trial or pilot new technology first?

A trial shows how the new equipment performs in the actual airfield environment and with the existing system, and what it means for maintenance, spares, training and lifecycle cost. It reduces the risk of committing a whole programme to something that does not fit.

Q5What new considerations come with modern control and monitoring?

Networked control and monitoring brings communications, software, data and cybersecurity considerations alongside the electrical ones, as well as the need for skills and procedures to use the new information. These are planned for as part of the programme rather than added afterwards.

Q6What happens to the legacy equipment?

Once the new equipment is proved and in service, the legacy equipment is taken out of service and handled through the decommissioning and disposal stages of the lifecycle. Records, spares plans and procedures are updated so that the airfield is not left maintaining two systems.
