In three months, circling over Delhi Airport due to congestion could become history as its three runways will be used simultaneously for almost the entire day. This move will take up runway movement from around 55-60 per hour to almost 80. During trials that are on at present, the airport has successfully handled 75-80 flights per hour. Sources said that when fully implemented by October, simultaneous operations would be carried out for most part of the day, except for a few lean hours. At night its usage would depend upon requirement since domestic operations completely cease for a few hours post midnight. The move has most benefitted low cost carriers and cargo operations as they are located close to the secondary runway 09/27. The decision to use all three runways simultaneously was taken since the main runway was facing massive congestion during peak hours.
