CHENNAI: Pilots flying into the city airport need to watch out for more than 300 obstacles on the approach paths of the two runways, according to terrain and obstacle data released by Airports Authority of India (AAI). These are buildings, high mast lamps, electric poles, mobile phone towers, water tanks and dish antennas atop buildings and hoardings.
In addition to the buildings, the metro rail’s elevated line and stations also pose a risk. The electric overhead cable poles of the metro rail line from airport to Alandur, Nanganallur metro station, canopy over metro rail lines from airport and St Thomas Mount to Alandur station and the Alandur metro rail station itself violate permissible height limit for structures around the airport.
