Avionics: Aviation Communication, Navigation And Aircrafts

Published: June 15, 2007

Every day the vast blue landscape above our heads is filled with non-stop flights and expeditions from all sorts of different types of aircraft. It is hard not to stare at the sky, observe the marvels of aviation, and wonder in amazement at how they are able to stay in the air and maintain their flight paths for such long distances. Traveling by air requires precision and absolute certainty that nothing will go wrong during the journey because failure could have catastrophic results for pilots and passengers.

These marvels in aviation are possible because of the complex inventions and discoveries that have resulted from the study of avionics. Avionics is the system of electronics that exists on board of an aircraft and makes it possible to do many different tasks in order to keep the aircraft stable and able to get from one destination to the next. Without avionics, the thousands of flights that are performed daily would not possible and the skies would be cluttered with unequipped aircraft.

Avionics includes the performance of numerous tasks for an aircraft. Aircraft avionics are usually located in the cockpit and can include the displays on board the aircrafts that gather information for flights, the flight control systems that limit pilot error and increase safety, collision avoidance systems that warn the aircraft of other aircrafts nearby, and weather systems that display the conditions that the aircraft will be flying through.

All of these examples are crucial parts of avionics, but the two most important parts that have existed for years and have been continually expanding are communications and navigation. Without these two components, aviation would just be a crapshoot for a pilot and the crew that are behind a flight.

The origin of avionics is said to be in communication. Communication is vital to any part of aviation because a pilot must be able to correspond with the ground control in order to find landing spots or to plot a course through a storm or an uncharted territory.

There are a number of communication devices on board for different types of aircraft. For military aircraft, there are radios in order to find targets or rescue spots as well as communicating back to the base. During commercial flights, communication devices are used to contact different aviation agencies for weather conditions or to communicate with different airports. They also can use communication on board to inform passengers of different situations.

In aviation, navigation can mean all the difference between a successful or disastrous flight. This part of avionics involves the plotting of where the aircraft is and where it is going throughout the different parts of the world. A preflight determination of the flight plan can be laid out through avionic systems in the cockpit ,and can assure the pilot of a charted course to the destination. Knowing the course of flight before the aircraft takes off is certainly a better option than planning as the flight is taking place. While flight plans may change during the flight, navigation plans can also change and the avionics will adapt the changes in order to maintain the stability of the flight.

While the wonder of aircraft transportation continues to progress and break boundaries that were unheard of a hundred years ago, avionics continues to be the backbone for the safety of all sorts of aircraft. Without avionics, aviation would be something that only daredevils and those with a taste of danger would attempt. Instead, avionics gives people all over the world a chance to experience flight and to visit places all over the world.
