How are slots allotted to airlines for operation form an Airport?

With the increase in air traffic at the major airports in the country, the capacity of many airports has been constrained. Therefore to ensure most efficient use use of airport infrastructure and in order to maximise the benefits to the greatest number of airport users, the Airport Authority of India (AAI) has a policy for allocation of constrained or limited airport capacity to airlines and other aircraft operators, through a transparent and equitable mechanism so as to ensure viable airport and air transport operations.

Search for Supersonic Transport and its Challenges

In October 1947 Chuck Yeager took the rocket-powered Bell X-1 through the sound barrier. After that humans have not looked back and any new fighter aircraft is naturally assumed to be able to sustanin supersonic speeds. However to date only two supersonic transport aircraft Concorde and Tupolev-144 have seen regular service. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde’s last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service.
