FIVE STEPS TO ASSURE NAVIGATIONAL SAFETY

摘要

The passage of objects through air or water is usually planned in advance. This is done graphically on a chart or analytically. The travel of the object is to be watched by the track. This is done at two Control Stations, one located on board the moving object, the other one located on Earth.Air trips are monitored on Earth at Airport Control Stations, equipped with radars and communications suite.In an airplane it is the cockpit with resources available to monitor the travel.Sea trips are monitored on Earth at Traffic Control Stations, equipped with radars and communications suite.In a ship it is the chart room with resources available to monitor the travel.The principal difference of the navigating bridge from the cockpit is that when in congested waters bearings are taken mainly by sight. In a plane bearings are found by instruments.
