Nowadays such systems as TCAS is very important for orientation in space.The last system we are going to talk is the flight management system (FMS). It is the head of all navigation and other systems. The FMS is a fundamental part of a modern airliner's avionics. A FMS is a specialized computer system. It automates a wide variety of in-flight tasks, reduces the workload on the flight crew to the point that modern aircraft no longer carry flight engineers or navigators. A primary function is in-flight management of the flight plan. The FMS can guide the aircraft along the flight plan. From the cockpit, the FMS is normally controlled through a Control Display Unit (CDU) which incorporates a small screen and keyboard or touchscreen. The FMS sends the flight plan for display on the EFIS, Navigation Display (ND) or Multifunction Display (MFD). The modern FMS was introduced on the Boeing 767. Now, systems similar to FMS exist on aircraft as small as the Cessna 172. In its evolution an FMS has had many different sizes, capabilities and controls. However certain characteristics are common to all FMS. No one modern aircraft cannot make flights without uniform system such like FMS. FMS calculates and unites all parameters during flight and provide safety trajectory. EXERCISES FOR BETTER REMEMBERING THE TOPIC I Listen and repeat the pronunciation of the words.
