Airport gets gadgets to beat fog
All vehicles that have access to the Delhi Airport tarmac will be fitted with transponders by December 15. Vehicles without transponders will be banned entry, the Airport Authority of India (AAI) has warned.
December 15 is also the date when the Category III B Instrument Landing System (CAT IIIB ILS) — a mechanism that will enable planes to land even in 50 metre visibility — will be made operational. "When an aircraft starts landing at such low visibility, it forces airlines and other airport agencies to ferry passengers and officials in vehicles from the aircraft. This increases the chance of the vehicles colliding either with each other or with an aircraft," said an official. The transponders, which cost up to Rs 20,000 will prevent such collisions.
