Delhi airport to undergo ILS calibration tomorrow; know details

India Nov 11, 2025

Heads up if you're flying in or out of Delhi!
The Indira Gandhi International Airport is doing a mandatory calibration on its Instrument Landing System (ILS) this Tuesday, specifically on Runway 10/28 from 11:30am to 1:30pm.
This quick two-hour calibration helps make sure planes land safely and smoothly—even with the airport handling over 1,500 flights every day.

Flight timings may be affected

Delhi International Airport Ltd (DIAL) says there might be some tweaks to flight timings during the calibration window.
The ILS is a big deal for keeping takeoffs and landings safe at India's busiest airport, so these checks are just part of making sure everything runs reliably for travelers.
