Chennai, Mar 23: A mock aircraft crash drill, using drones for the first time, was conducted at the SRM University Campus at suburban Kattankulathur in association with the Airports Authority of India (AAI) on Friday.
The mock aircraft crash was done to simulate the search and rescue operations.
Search and rescue operation was carried out once a year at various airports and this year the mock exercise was held at Chennai and the AAI has partnered with SRM Institute of Science and Technology to conduct the search and rescue mission. 
The mock drill was done to test the defence preparedness of various agencies in the event of any contingency/disaster and also to improve the coordination between various agencies that included, Coast Guard, IAF, Navy, health, fire, police departments, INMCC, various NGOs and SRM. 
This was the first time drones were used for the Search and rescue operation for an aircraft, a release from SRMIST said. 
To make it possible for the rescue team to inspect the area from above and to accomplish it, a drone, designed by a 20-member Team (SRM SCRO), was used for the search operation. 
The drone was capable of carrying two kg payload having imaging and transmission system, which transmits the live feed video (4K resolution) to the ground station, from where it was transmitted to ATC (Air Traffic Control). 
Soon after the aircraft 'crash' took place, the GPS signal would be transmitted to the satellite and the ATC authorities would get the GPS coordinate in terms of minutes accuracy(1.85km). 
To improve positioning accuracy and identifying the proper location and condition of the crash area, the ATC authorities calls for the drone assistance by providing the GPS coordinate. 
Since the area is 1.85 km, the area mapping algorithm was utilised to map the given GPS location with two meter location accuracy. 
The drone was made to fly and map the entire area, when the ATC authorities identify the crashed airplane in live feed video.
The respective GPS coordinates in seconds accuracy (20 meter) and the rescue sent to the crash site for taking up the rescue operation. UNI
