Minister of State for Civil Aviation K C Venugopal said in reply to a question that there were 23 'airprox' (air proximity or near-miss) incidents during the last one year but these were not caused by shortage of air traffic controllers.
He said the Airports Authority of India has recruited 318, 294 and 188 air traffic controllers (ATCOs) in 2010, 2011 and 2012 respectively and its Board has approved the creation of 680 more posts for future requirements.
Venugopal said six flying slots of IndiGo, GoAir and Jet were withdrawn by DGCA as they violated the aviation regulator's instructions on flight operations during foggy conditions, leading to diversion of six flights from Delhi on January 29 and 30.
In response to another question, Civil Aviation Minister Ajit Singh said Air India's pilots union Indian Commercial Pilots Association had raised issues relating to 'unreliable weather radars' in Airbus A-320 aircraft.
"Though one radar is sufficient for safe operation, these aircraft have two independent radar system for redundancy and safety. Since there is no safety issue in this case and as there are no such mandatory modifications recommended from the manufacturer or DGCA in respect of weather radar, no action is proposed to be taken," Singh said.
