Which type of chart is utilized for flight planning and navigation at low altitudes and medium airspeeds?

The World Aeronautical Chart (WAC) is designed specifically for navigation and flight planning at lower altitudes and medium airspeeds. These charts provide essential information for pilots flying under Visual Flight Rules (VFR), which typically occurs at lower altitudes, allowing for effective navigation in various areas, including rural and less congested regions.

WACs feature a scale and layout that support visual navigation, highlighting relevant terrain features, airspace boundaries, and navigation aids. This makes them ideal for pilots operating below 10,000 feet, where detailed local information is critical for safe navigation.

In contrast, VFR Terminal Area Charts are geared towards operations in and around busy terminal airspace, providing detailed information for maneuvering safely in proximity to airports. Enroute High Altitude Charts cater to high altitude navigation, primarily for aircraft flying at altitudes above 24,000 feet. The Canada Air Pilot primarily serves a different regulatory environment and presents information specific to Canadian aviation needs.

Thus, the World Aeronautical Chart stands out as the appropriate choice for low-altitude, medium-speed flight planning and navigation.
