Final answer:
Star charts and coordinates are navigational charts used by private pilots. Star charts provide graphic charts of the sky to help pilots identify stars, while coordinates indicate a specific location on Earth.
Step-by-step explanation:
Navigational charts used by private pilots include star charts and coordinates. Star charts provide graphic charts of the sky and can be obtained from free online resources like Skymaps. These charts help pilots identify and locate stars and celestial bodies for navigation purposes. Coordinates, on the other hand, are numerical values that indicate a specific location on the Earth's surface. Private pilots use coordinates to determine their position and plot their course on a chart.
