Relocation of PAPI

Project Overview
As part of Donegal Airport’s runway heading change, atg airports was selected to deliver a turnkey solution for the relocation and re-installation of Precision Approach Path Indicators (PAPIs) on both runway ends. The project required a high level of technical expertise, seamless coordination, and a focus on operational continuity—all of which were delivered to exceptional standards and ahead of schedule.

Project Objectives
• Relocate PAPIs by 100 meters on each runway end
• Construct new compliant infrastructure
• Move, install and align existing LED PAPI units
• Minimise operational disruption during works

Strategic Execution
Our team expertly managed all aspects of the relocation, from groundwork to final alignment. The numbering of Runway 03 to 02, and 21 to 20, required reconfiguration of the PAPI
circuits to suit new runway requirements.

Key milestones included:
• Construction of new concrete bases incorporating delethalisation for enhanced safety
• Installation of durable duct systems and cable pits to house electrical systems
• Deployment of LED PAPI units at the 20 End, and relocation of existing units to the 02 End
• Alignment completed to exact aviation specifications using www.atgairports.com our specialised teams

Electrical & Infrastructure Upgrades
The installation of modern electrical pit furniture—including new transformers, mounting brackets, and earthing systems— ensured optimal functionality and future-proofing. Every
component was selected for reliability and ease of maintenance, a key value proposition for airport authorities seeking longterm cost-efficiency.

Flight Check & Handover
Upon project completion, a full flight check validated the precision alignment and operational readiness of the new PAPIs. The airport was provided with complete documentation, including alignment angles and O&M manuals, ensuring full compliance and ease of future servicing.

Outcomes & Benefits
• Enhanced Airfield Safety: Accurate PAPI alignment improves approach visibility and landing precision
• Operational Continuity: Zero disruption to airport operations during installation
• Regulatory Compliance: All work carried out to the required standards
• Future-Proof Infrastructure: Durable, low-maintenance electrical and structural solutions

Conclusion
This successful delivery at Donegal Airport reflects atg airports’ commitment to innovation, compliance, and client satisfaction. By completing the PAPI relocation project ahead of schedule and to exacting standards, we have reinforced our position as a trusted partner in airfield ground lighting solutions across the UK and Ireland.
