An airplane is flying at an airspeed of (200) miles per hour headed on a SE bearing of (140°). A north wind (from north to south) is blowing at (16.2) miles per hour, as shown in Figure (PageIndex{1}). What are the ground speed and actual bearing of the plane? Figure (PageIndex{1}) Ground speed refers to the speed of a plane relative to the ground. Airspeed refers to the speed a plane can travel relative to its surrounding air mass. These two quantities are not ...
