Metro Rail to reduce runway in Chennai airport

Chennai: The alignment of Metro Rail inside the airports authority’s land at Chennai is perceived to create operational limitations for the secondary runway currently being expanded to allow landing of bigger aircraft.
While the Airports Authority of India (AAI) is expanding the secondary runway, by constructing a bridge over Adyar river, experts say that the construction of Metro Rail will reduce the runway utilisation area by 330 metres.
The secondary runway, which is 2,085 metres long now, is being extended by 1,032 metres, but the displacement of 330 metres for landing and take-off will put a question mark on the usage of the runway for bigger aircraft, say experts.
The International Civil Aviation Organization’s safety specifications include an eight feet compound wall with 1.5 ft tall concertina or barbed wire around the airport perimeter area. It means AAI will have to construct another wall after it hands over the land to Chennai Metro Rail Ltd (CMRL).
As per CMRL plan, metro rail will enter the AAI land after it crosses the defence land and deviate into GST road just before the new customs office.
