Kolkata: The distance between successive flights in the touchdown sequence has recently been slashed by 2km to pack in more landings and takeoffs at Kolkata airport during crunch hours.
"We have reduced the spacing or separation between two arriving flights from 13km (seven nautical miles) to 11km (six nautical miles). During congestion, when there may be about 30 flights converging into Kolkata, we can now reduce around 60km or 30 nautical miles. That is enough space for five more flights to join the queue and land in an hour, thus increasing the runway capacity from 30 flights an hour to 35 flights," said Kolkata airport regional executive director K L Sharma.
The higher separation between incoming flights when there is a takeoff slotted between two landings has also been changed. While the required separation was for nearly 15km (eight nautical miles), it has been reduced to 13km.
The sky over the city gets congested four times a day with nearly 30 or more flights jostling for space to land before they run low on fuel and make a dash to touch down at an alternative airport. The capacity augmentation will be particularly helpful during peak hours in the morning, afternoon and evening. Last year, there had been several instances when flights had to divert to Bhubaneswar as fuel reserve got depleted beyond the threshold level while circling over Kolkata.
