 Meanwhile, Delhi's airport flight operations will also be impacted, as one of its main runways, 11R/29L, will be shut down. This closure is expected from mid-February to June for major upgrades. The upgrades include enhancement of the Instrument Landing System (ILS) to CAT III-B standards and installation of a new rapid exit taxiway (RET). The shutdown has been planned with the Ministry of Civil Aviation and other stakeholders to minimise disruptions. The airport has four runways, so flights will be managed using the other three runways.
