AAI had undertaken a detailed study of the process of hiving off the ANS entity through experts, Civil Aviation Minister Ajit Singh informed the Rajya Sabha during Question Hour.
"Various alternatives suggested by the study so far are being examined in the Board of AAI," he said.
The issue of separating Air Traffic Control (ATC) services from aerodrome operator had been pending before the government for a long time.
Various committees had recommended this, starting from 1976, the latest being Naresh Chandra Committee of 2004.
"After detailed expert study in 2008 and careful examination, the Government had decided to aggregate all ANS activities under a separate Member (ANS) in the first stage," Singh said.
The objective behind setting up a separate entity for air navigation services is to give undivided focused attention to augmentation, upgradation and improvement of communication network surveillance and air traffic management to match with the future "huge growth" of aircraft movement.
"Further it will result in separation of airport operator (AAI) and air navigation service provider (CNS/ATM) thereby avoiding any conflict of interest situation which is (in) line with ICAO recommendations," the minister added.
