Enroute charts are specialized navigation maps used by pilots during flight to help them navigate between departure and arrival airports. These charts provide essential information such as airways, waypoints, and navigational aids, ensuring safe and efficient routing through controlled airspace. Typically, enroute charts are part of the Aeronautical Information Manual and are designed for use at cruising altitudes. They include details like altitude restrictions, communication frequencies, and nearby airports, allowing pilots to plan their routes and make informed decisions while in the air.
