If a topographic map is not available, what is the next best option for flight?

Selecting a Joint Operations Graphic (JOG) map as the next best option for flight in the absence of a topographic map is a sound choice for several reasons. JOG maps are specifically designed for military operations and provide detailed terrain information, which includes elevation contours, prominent terrain features, and other critical navigation details that can assist pilots in understanding the landscape they are flying over.

These maps are typically produced at a scale that balances the need for detail with usability in aviation contexts, allowing for effective route planning and situational awareness. The rich information contained in JOG maps aids in avoiding obstacles, ensuring safe flight paths, and navigating in various terrain types.

While other types of maps, such as route maps, official navigation charts, or flight planning charts, may provide useful information for navigation, they often lack the specific terrain details and elevation information critical for terrain flight operations. Therefore, JOG maps stand out as the best alternative when topographic maps are unavailable.
