Proactive measures initiated at the IGI Airport were helpful in minimizing the ripple effects at IGIA arising out of the disruption over northern European airspace due to volcanic ash.
A large number of flights to India pass through affected airspace over Europe. Many of these flights had to be cancelled, rescheduled or diverted. DIAL & Air Traffic Control officials at IGI Airport worked closely to ensure that all incoming passenger flights from London & other European destinations were closely monitored and made to land on time. However, due to restrictions in the European airspace, many of these flights could not take off for their return journey. This led to a shortage of parking bays at IGI for incoming aircraft,
To manage the situation and reduce inconvenience to passengers, DIAL and ATC officials diverted incoming cargo flights to other airports under due intimation to their operators. The parking bays available at the International cargo apron were then used to park incoming passenger aircraft and passengers were ferried to the terminals by coaches. Still there was shortage of parking bays. DIAL Operations team - in close coordination with ATC - decided to park five wide bodied aircrafts, after the passenger disembarkation at the terminal, on adjoining aircraft taxiways which are currently not used due to the runway 28 rehabilitation work.
All these efforts ensured that passengers and airlines faced minimum inconvenience and flight operations at IGI Airport continued with near normalcy despite the unprecedented situation.
