After sporadic drizzle, Delhi’s air quality improves; poor visibility causes flight diversions

New Delhi: After a spell of sporadic but consistent drizzle, the air quality in the national capital on Monday entered the “satisfactory” category but after Tuesday, the air quality index may deteriorate, according to weather predictions.

Due to low visibility at Delhi airport on early Monday morning, ten flights, including one international flight, have been diverted so far, airport sources said.

Most of the diversions have been due to non-compliance for Cat III B operations.

CAT III-B Instrument Landing System (ILS) that allows flights to land safely in low visibility with Runway Visual Range (RVR) of up to 50m with a decision height of 15m.

“Overall air quality over Delhi is in satisfactory category after a sporadic but consistent drizzle. AQI may slightly buildup but predicted to remain in moderate category until tomorrow and thereafter will oscillate between moderate to poor,” according to SAFAR.
