What Is Navigation

Finding the way from one place to another is called NAVIGATION.

Aircraft Navigation is the art and science of getting from a departure point to a destination in the least possible time without losing your way.

In the past, plotting on the paper or on the map a course towards a specific area of the earth used to be a task assigned to a specialized member of the aircraft’s crew such a navigator. Such a task was quite complicated and not always accurate. Since it depended on the observation, using simple maps and geometrical instruments for calculations.

Today, aerial navigation has become an art which nears to perfection. Both external Navaids (Navigational Aids) and on-board systems help navigate any aircraft over thousands of miles with such accuracy that could only be imagined a few decades ago.

Pilots have various navigation aids that help them take-off, fly, and land safely.

One of the most important aids is a series of air route traffic control, operated throughout the world.

Most of the traffic control uses a radar screen to make sure all the planes in its vicinity are flying in their assigned airways.

Airliners carry a special type of radar receiver and transmitter called a transponder.

It receives a radar signal from control center and immediately bounces it back.

When the signal got to the ground, it makes the plane show up on the radar screen.

There are various navigational aid equipment and system which you will study further in details during pilot training modules.
