Why should a pilot use a nautical map?

A pilot should use a nautical map because it provides essential information about water depths, navigational hazards, and the location of buoys and other aids to navigation, which are crucial for safe navigation over water. Nautical maps also indicate tides, currents, and other environmental factors that can affect flight paths. Using these maps ensures pilots can plan their routes effectively and avoid potential dangers while maintaining situational awareness. Overall, they enhance safety and efficiency during flight operations over maritime areas.
