Aeronautical Chart


An Aeronautical Chart is a map designed to assist in navigation of aircraft, much as nautical charts do for watercraft, or a road map for drivers. Using various scales, these charts depict features helpful for navigation by air, safe altitudes, and aeronautical and navigational obstacles.

What is an Aeronautical Chart?

An Aeronautical Chart is a specialized map that provides detailed information designed primarily for use by pilots but can also be utilized by air traffic controllers and aviation experts. These charts contain a plethora of information such as terrain, minimum safe altitudes, locations of airport facilities, airspace boundaries, visual and radio navigational aids, obstacles, and air routes. They are primarily created using Geographic Information System (GIS) technologies.

There are different types of Aeronautical Charts, for example, VFR (Visual Flight Rules) charts are used by pilots flying under VFR and provide detailed information of things that a pilot might see while in flight. On the other hand, IFR (Instrument Flight Rules) charts are used by pilots who rely on flight instruments and provide navigational information that is processed by onboard avionics.

The aim of these maps is not only to assist in successful navigation but also to ensure the safety of air travel. They are essential tools in planning cross-country flights as they provide the necessary information to make informed decisions about navigation, weather, and emergency planning.


Who uses Aeronautical Charts?

Aeronautical Charts are primarily used by pilots for navigation during flights, both for visual reference and when using aircraft's instruments. Additionally, these charts are also useful for air traffic controllers, airport planners, aviation regulators, and other aviation-related professions.

How often are Aeronautical Charts updated?

Aeronautical Charts are updated regularly. The frequency of updates can vary depending on the region and type of chart, but it is typically every six months to one year. This ensures that the pilots have the most recent and accurate information for safe and effective navigation.

What information can you find on an Aeronautical Chart?

An Aeronautical Chart includes detailed and varied aviation-specific information. This includes but is not limited to airport locations, runways, frequency data, airspace classifications, navigational aids, relief data, geographical and man-made obstructions, and topographical features relevant to aviation.

What is the difference between VFR and IFR Charts?

VFR (Visual Flight Rules) and IFR (Instrument Flight Rules) Charts are two different types of Aeronautical Charts used for different flight plans. VFR charts are primarily used for navigation by visual reference and include data like terrain contours, roads, and visual landmarks. IFR charts, however, are used for navigating by instruments and focus on airspace classifications, airways, navigational aids, and airport instrument procedure information.
