New Delhi: Severe mist prevailing in Delhi forced authorities to abandon all services from the Delhi international airport. More than 100 air services are disrupted till this date in Delhi due to heavy mist. Because of this climatic condition nothing can be viewed properly within the 50 meters circumference. The automatic CAT technology which has been used to land airplanes requires the visibility of 50 meters circumference. That is why the services are forced to abandon by the authorities. This is the second consecutive day that the operations in the Delhi airport are disrupted.
