Over 90 flights hit due to thick fog, cable fault at airport

New Delhi, Jan 2 (PTI) Thick fog and a cable fault played
havoc with flight operations in and out of Delhi since the wee
hours today as over 70 domestic flights were delayed, six
cancelled and 17 international services diverted to some
other cities.

Almost 45 domestic departures and 25 arrivals were delayed
by two to five hours and 17 international flights were
diverted to Jaipur, Ahmedabad and Mumbai. Six domestic
flights, including those belonging to Jet Airways, JetLite,
SpiceJet and Kingfisher, were cancelled, airport sources said.
No flight could take off or land from 0200 hours when
runway visibility dropped to 100 metres and a major glitch
occurred in the cables connected to the Instrument Landing
System (ILS) that measures and provides real-time runway
visibility data to the Air Traffic Control (ATC) tower. This
forced the ATC officials to suspend all flight operations.
The cable fault was rectified partially by 1000 hours and
flight operations resumed at 1030 hours, the sources said,
adding that several of the diverted international flights were
given the green signal to come in to Delhi.
With runway visibility improving by mid-day to 800 metres,
flights were resumed using two main runways equipped with
Category-III B ILS that allows flight operations when runway
visibility is less than 100 metres.
Earlier, none of them could be used as the instrument
could not provide the information to the ATC due to the cable
fault, they added. PTI SMJ
