With the development of aircraft equipment,
conventional navigation is the shift from performance based navigation (PBN).
As is known, conventional navigation is based on ground-based navigation aids;
however, PBN is based on aircraft avionics and performance. In this paper, a
new method called Point Merge System (PMS) considered as one of PBN procedures
will be introduced. PMS has many benefits related to fuel savings and emission
reductions by implementing Continuous Descent Approaches (CDAs). A new PMS
standard arrival route (STAR) model will be designed in radar simulation and it
will be suggested.
With rapidly growth in industrial sectors,
in order to meet the demand, the usage of Ultra High Voltage (UHV) is needed.
High voltage (HV) is between the range of 52 kV and 300 kV. In case of voltage
above 800 kV, it can be defined as UHV. With the development of technologies in
the world, it could be seen that Japan, Russia, Italy, Brazil, America (U.S), and
Canada began to improve UHV in the 1960s and 1970s. In addition, China, a
leader developing country for UHV technologies in the world, started UHV
technologies in transmission, in 1980s. Nowadays, seven transmission lines are
in operation in China. In this study, the concept of HV and UHV will be
introduced. Especially, UHV transmission in the worldwide will be researched.
Then, the historical development and current situation of UHV will be analyzed
and the assessment for Turkey will be done.
