Flight operations at Patna's Jayaprakash Narayan International Airport will now be safer even when the visibility is poor.
India Meteorological Department (IMD) has installed Drishti - an indigenously developed transmissometer that will record exact visibility readings for pilots even when visibility is less than 2,000m.
The system started functioning at Patna airport from last week.
A transmissometer helps the pilot to land and take-off safely, especially when visibility is poor. Visibility condition at the Patna airport has always been a concern because of the short stretch of the runway. It did not have any digital machinery to measure readings before Drishti.
"A transmissometer has been installed adjacent to the runway near the touchdown point for flights," said airport assistant general manager (air traffic management) Santosh Kumar. "It has three components - a sensor, a receiver and a transmitter. There is a gap of 30m between the receiver and transmitter. The censor records visibility readings and the data is continuously sent to the air-traffic controller."
Senior officials at Patna airport said the runway visibility range was three to five kilometres but it reduced considerably in case of dense cloud cover during monsoon or fog in winter. This leads to cancellation and diversion of flights.
