Traffic Collision Avoidance System (TCAS)

Before we go further on what is TCAS, I would like to refresh on few accidents involving aircraft in mid-air collision.

Nov 1996 – Mid-air collision between Saudi Airlines Flt 763 and Kazakhstan Airlines Flt 1907 which killed 349 passengers onboard.

Sep 1976 – Mid-air collision between British Airways Flt 476 and Inex-Adria Aviopromet Flt  550 which killed 176 people onboard.

Dec 1992 – Air crash between Libyan Arab Airlines Flt 1103 and Libyan Air Force Mig-23 Flogger on the way to Tripoli International Airport which brings fatality of 159 people including air crew.

Based on the tragedies occurred together with some other mid-air collision, a new kind of technology invented to avoid such this things from happening in the future. It’s called Traffic Collision Avoidance System (TCAS) to be used in every commercial aircraft nowdays. It is a mandatory requirement as said International Civil Aviation Organisation (ICAO) who is the global aviation authority. Now let’s dig what is TCAS and why it is too important to implement this technology on aircraft?

For y’all info, the word ‘photography’ is taken from Greek which photo means ‘light’ while graphien means ‘to draw’. It does make sense since the images that we took are for our own memory.  The word photography used in 1839 by a scientist named F. W. Herschel. Let us dig who is the real person invented the camera and what kind of camera he created.

Revolution of Telecommunication & Telephone

Communication has become an important element to human beings since their existence on earth. It is used to deliver and receive data among each other (interaction). Since communication becomes a need in human life, therefore a revolution of communication keeps expanding. 

 At the earliest stage, the way of communication is by using smoke and drum sound. Back in the time, when people saw the smoke or hear the drum, they will know something is happening. When they received the signal, people will rush to community centre to find out what exactly happened. This kind of communication has few weaknesses and people start inventing something more reliable than this.
