Noida International Airport Achieves Another Milestone with Successful Calibration of Instrument Landing System

Noida International Airport (NIA) has successfully completed the calibration of the Instrument Landing  System (ILS) and Precision Approach Path Indicator (PAPI). A Beech King Air 360ER from the Airports  Authority of India (AAI) began the calibration process on Thursday, 10th October, with the process  concluding on 14th October 2024. The calibration, carried out by AAI with support from the Directorate  General of Civil Aviation (DGCA), represents a crucial milestone in NIA’s journey towards operational  readiness, ensuring the highest safety standards for aircraft operations at the airport. The ILS is a radio  navigation system that provides precise guidance to pilots during approach and landing, particularly in low  visibility conditions. The system consists of two main components:

*The Localizer helps align the aircraft with the runway centre-line, providing horizontal guidance.

* The Glide Path Antenna provides vertical guidance to the aircraft ensuring a safe and smooth descent.
The ILS is an essential safety system that enables pilots to land safely even when visibility is significantly  reduced due to fog, rain, or other adverse weather conditions. This capability is crucial for maintaining  operational efficiency and minimizing delays at the airport. Additionally, the PAPI is a system of lights  positioned beside the runway, designed to provide visual indication to pilots regarding their correct  descent angle during the final approach. The successful calibration of ILS and PAPI is a significant step  forward for Noida International Airport as it progresses towards its operational launch.
