Part 3:
Introduction:
Flight management System or the FMS is the fundamental component that is included
in the modern airliners avionics. This is one of the specialized computer systems which is
associated with the automation of the various in-flight tasks along with helping in the
reduction of the workload upon the flight crew up to a point where the modern civilian
aircrafts no longer need to carry the flight engineers or the navigators (Zheng & Zhang,
2018). One of the primary functions of the FMS incudes the in-flight management of the
flight plan by making use of numerous sensors for the purpose of determining the position of
the aircraft. Additionally, the FMS is also capable of guiding the aircraft all along the planned
flight. The FMS is generally controlled from the cockpit by making use of the CDU or the
Control Display Unit which is incorporated with a small screen along with a keyboard or a
touchscreen. The FMS is then associated with sending the flight plan for display to the EFIS
or the Electronic Flight Instrument System, the ND or the Navigation Display and the MFD
or the Multifunctional Flight Instrument System. So, the FMS can be summarized as the dual
system that consists of the FMC, the CDU and a cross talk bus.
Computers have been acting as the integral part of the aviation industry since the
beginning when the airplanes were associated with featuring the on-board analog computers.
The Flight management system is associated with the usage of super computers so as to
automate the various in-flight tasks. Besides the super computers are associated with the
usage of the sensors so as to reduce the workloads of the pilot as well as the rest of the crew.
Name of the Super Computer and the specifications:

The super computer that is to be used for this purpose is the Tianhe-2A. the major
reason lying behind choosing Tianhe-2A is that in the FMS it provides simulation along with
analysis and government security application. This would be having almost 16000 computer
nodes along with a two Intel Ivy Bridge Xeon processors along with Xeon Phi coprocessor
chips. Each of the 16000 nodes would be processed by the 88 gigabyte of the memory and the
total CPU plus coprocessor memory is around 1375 TiB.
Discussion:
The Supercomputers have been associated with resulting in an incredible feat of the
aviation engineering. The usage of the super computers makes the airplanes larger and faster
than any other which are predated. The usage of the super computers has also been associated
in helping in saving a lot of money as they are mainly used for the purpose of managing the
millions of calculations per second. FMS acts as the fundamental for the operations
conducted by the modern avionics system and has the aim of automating some of the in-flight
tasks which in turn is associated with reduction in the workload of the flight crew. The major
reason for designing the FMS is for increasing the flight safety as well as the efficiency by
providing the crew of the flight and the onboard avionics system with the data which are
necessary for the effective aircraft operations (Altava et al., 2018). The fundamental function
of the information system proposed is enabling of the flight crew to program the route right
starting from the takeoff till landing. Additionally, the autopilot along with the flight directors
is considered to be set which is associated with following the path that is designated for the
destination (Altava et al., 2018). This FMS can be used by the small private aircrafts as well
as by the large commercial jetliners. The FMS would be consisting of variety of controls as
well as instrumentation and the four major components of the FMS includes the following:

The automatic Flight control or the Automatic Flight Guidance System: This are the two
systems which would be associated with the utilization of the various sensor information that
are collected by the supercomputers from the aircraft systems and besides this the systems
would also be responsible for automatic maneuver of the aircraft by making use of the mode
that would be selected by the crew members in cases if the autopilot is engaged (Ramasamy,
Sabatini & Gardi, 2015). Whenever the autopilot is disengaged the guidance commands that
would be displayed to the pilot would help in flying the aircraft manually along the path that
has been assigned.
Flight Management Computer: This mainly includes the computer system which is
associated with the utilization of a database by the super computers of the FMS which are
responsible for the facilitation of the routes which are pre-programmed and are then added to
the system by making use of the data-loader. The system is also associated with the
continuous updating of the information related to the position of the aircraft by referring to
the navigation aids that are accessible (Tian, Liu & Zhang, 2018). After this the aids which
are applicable are selected automatically at the time of updating the information.
The Auto-pilot is another feature provided by the super computers so as to be utilized for
flying the planes at longer distance by taking very small amount of help from the pilots. The
super computer of the FMS would be assisting in the taking off and landing of the airplanes
without taking assistance from humans making the entire aviation automated.
The Aircraft Navigation System: This is considered to be the integrated package that is
associated with tracking the position of the aircraft in a continuous way. This would be
featuring the GPS or the Global Positioning System and the IRS or the Inertial Reference
System data along with which the receivers that would gather the Input from the ground-
based flight navigation aids.
