In a first in the country and second in Asia, Mangaluru International Airport (MIA) has commissioned a runway approach lighting system featuring Airfield Lighting Intelligent Management Systems (ALIMS) mounted on specially engineered towers.

The system is designed to provide pilots with enhanced visual guidance during the critical final stages of landing, particularly under conditions of reduced visibility, at a tabletop facility.

The ALIMS extend 900 metre outwards from the runway threshold. Most of these towers rise higher than the iconic Qutub Minar (in Delhi), highlighting the scale and engineering complexity involved.

“This project stands out as one of the most unique and first-of-its-kind airfield lighting installations in India. Notably, the facility is only the second of its kind in Asia, placing MIA among a select group of airports worldwide, with such advanced infrastructure,” a spokesperson of the airport said.

The Precision Approach Lighting (PAL) Category I system for Runway 24 has been commissioned following approval from the Directorate General of Civil Aviation (DGCA).

“With commissioning of this feature, the airport further strengthens its commitment to safe, reliable, and efficient aircraft operations while meeting regulatory compliance,” the spokesperson said.

A rare global project

The installation involved mounting precision approach lights on elevated lattice structures, an approach that is rare globally, and was earlier identified as a distinctive feature of the project design. Each lattice structure, numbering 17, has a barrette with four lights, and a sequential flashing light in the centre. The barrette can be lowered to the ground for maintenance.

“A key highlight of the project’s execution is the zero-accident record maintained throughout the construction phase, underscoring the airport’s adherence to the highest standards of safety, planning, and execution,” the spokesperson said.

Enhanced aviation safety

The commissioning of the PAL Category I system brings multiple safety benefits.

The system provides a clear visual reference for pilots during approach, particularly in low visibility conditions, such as rain, fog or haze. The lighting configuration enables precise alignment with the runway centreline. Given the topographical characteristics of the tabletop runway in Mangaluru, the system significantly improves pilot confidence and approach stability. Better visual cues aid smoother landings, improving operational efficiency and minimising disruptions. The use of ALIMS ensures centralised monitoring and efficient management of airfield lighting systems.

“The PAL system complements ongoing airside enhancements undertaken by the airport, including upgrades in runway lighting and safety infrastructure, reinforcing its long-term vision of becoming one of the safest tabletop airports in India,” the spokesperson said.

“The commissioning of the PAL system reflects the airport’s continuous focus on adopting advanced technologies to enhance aviation safety and passenger confidence,” the spokesperson added.
