Raipur, Sep 11 (PTI) Flight operations resumed at Raipur airport in Chhattisgarh on Thursday after a disruption caused by a lightning strike, an official said.

As many as five IndiGo flights were diverted to nearby airports due to damage to the DVOR (Doppler VHF Omnidirectional Range) system at Swami Vivekananda Airport on Wednesday, he said.

DVOR is a ground-based radio navigation system that helps aircraft determine their position and direction relative to a destination.

"On Wednesday at around 6 pm, navigational facility DVOR got unserviceable due to heavy lightning, following which some flights were diverted. After lot of efforts by a well-trained team of CNS (Communication Navigation and Surveillance) and all sections of Airports Authority of India, Raipur DVOR facility was restored on Thursday at 6.30 pm," a statement issued by an airport official said.

Flight operations resumed from 2 pm, it added. PTI TKP BNM

Aviation navigation outage from lightning disrupted operations; DVOR repaired and flights resumed after airport technical teams restored service. Lightning rendered the DVOR navigational facility unserviceable, causing diversion of commercial flights and temporary suspension of normal operations; CNS and airport operational teams repaired and restored the DVOR the following day, allowing phased resumption of flights.
