FE Explained: How do flights land safely despite fog and low visibility? The wizardry tech that makes it possible!

On Sunday morning (January 14, 2024), more than 100 flights got delayed, 10 flights were diverted, and some were even canceled at the Delhi airport as low visibility due to dense fog conditions hit flying operations.

Every winter, it’s the same story at Delhi and other major/minor airports around the country. Agitated passengers get stranded for hours and sometimes even a day waiting for the green ‘Now Boarding’ sign to turn up on the Flight Information Display Systems (FIDS).
