Case Study: Illuminating the Skies – Aircraft Warning Lights for the North York Moors Mast

Location: North York Moors, UK
Client: National Broadcast Infrastructure Provider
Structure Height: 682m (306m mast on a 376m hill)
Duration: Completed August 2023
System Type: ICAO-Compliant Aircraft Warning Light System

Project Overview

Following a fire that destroyed the original 309m mast in 2021, a new 306m television transmitter was constructed, bringing the total aerial height to 682m—making it one of the tallest structures in the UK. Given its altitude and location within busy airspace, a robust aircraft warning light (AWL) system was essential.

Airspace Role

Airspace was tasked with designing and installing the AWL system. Our engineers developed a custom solution that exceeded ICAO safety standards, with a focus on reliability, visibility, and rapid deployment. Coordination with the client ensured the system met all site-specific and regulatory requirements.

Key Challenges

• Severe weather in the North York Moors—strong winds and rain delayed climbing and electrical work

• Working at extreme heights required strict health & safety planning

• Urgent timeline to restore broadcast services and airspace safety

Outcome

Despite weather-related setbacks, the project was delivered on time. The new AWL system is fully operational and protects one of Britain’s highest structures with 360° visibility and 24/7 reliability.

Airspace is proud to have contributed to both aviation safety and the restoration of national broadcast services in the region.
