Operational navigation chart

An operational navigation chart is like a big map that shows pilots and air traffic controllers where they are and where they need to go when flying an airplane. It has lots of information on it, like symbols and colors that help people understand what things mean.

There are different kinds of operational navigation charts depending on where you are flying. Some show only land while others show both land and water areas. They also show things like airports, runways, mountains, and rivers. These are important things to know because they can affect how the airplane needs to be flown.

Pilots use the operational navigation chart to plan their flight path and make sure they are following the correct route. Air traffic controllers use it to help guide planes in the right direction and avoid any other planes or obstacles in the sky.

Overall, an operational navigation chart is like a big map that helps pilots and air traffic controllers fly airplanes safely and efficiently.
