“Normally during a VVIP visit, no flight movement is allowed three minutes prior to landing and three minutes post landing. But during Obama"s visit, this period may be extended to six minutes before and six minutes after the aircraft lands," airport sources said.
They said that as per the plan, no clearances would be granted to any flight either to land or take-off during that period.
Two US Airforce Jumbos and four helicopters, which have surveillance and bombing capabilities, have already landed at the Chhatrapati Shivaji International Airport ahead of the President visit.
However, sources said civil aviation authorities here were yet to receive a formal communication about the American President"s flight schedule.
In the case of such a high level visit, the air traffic control and other related agencies are informed of the flight schedule at least 24 to 48 hours in advance, they added.
