Flight Following System
The multilateration system is a new helicopter tracking system for the North Sea, the first in the world to be used for offshore operations. It enables helicopter positions to be displayed, in real time, to the air traffic controllers on their radar display without using radar.
A big advantage of the system is that, should a fixed wing aircraft be in the area, it too will be displayed on the screen in the control tower, drastically reducing the risk of near miss incidents or collision, such as the near miss between a helicopter and a military aircraft in 2004.
