Abstract:
The use of autonomous design system technologies in aviation now days is far beyond
human thinking back 50 years ago, These technologies have been produced to make
human life easier. This technology is also including auto landing system (ALS), ALS
is used to land an aircraft automatically without human operation. This system is built
to reduce an aircraft crash due to the pilot's fault or external condition such as strong
wind and bad whether. For this project, ALS is developed by using system
programming language such as Very High Speed Integrated Circuit Hardware
Description Language (VHDL). VHDL is a language for describing digital systems.
VHDL is intended to support the hierarchical design, documentation, and simulation
of hardware from simple logic gate to complex digital systems. Hardware designs can
be specified as purely behavioral descriptions, data flow description, structural
description, or any mixture of behavior, data flow and structure. The versatility of
VHDL allows it to be used for this auto landing system circuit technology while
remaining independent of underlying implementation. By using this language, ALS is
developed by combining three subsystems which are control unit, comparator and
stabilizer subsystem.
