How do you access the nearest airport feature on a GPS?

To access the nearest airport feature on a GPS, rotating the large knob to the nearest page is the correct method. Many GPS devices specifically designed for aviation have a dedicated interface that allows pilots to navigate through various features. By using the large knob, you can quickly cycle through the available pages or menus, including those that display information on nearby airports. This function is particularly useful during flight for locating alternate landing sites or nearby facilities.

Each GPS device may have different configurations and button layouts, which means that utilizing the knobs can be more intuitive and efficient than relying solely on buttons or touchscreen inputs. The other methods mentioned, such as pressing buttons or using the map feature, may not directly lead to the nearest airport information because they could involve multiple steps or require navigation through different menus.
