Which technique should a pilot use to scan for traffic to the right and left during straight-and-level flight? How can you determine if another aircraft is on a collision course with your aircraft? What preparation should a pilot make to adapt the eyes for night flying?
Because of this designation, longitude is measured in degrees west or east of the Prime Meridian. For example, 30Â°E, the line passing through eastern Africa, is an angular distance of 30Â° east of the Prime Meridian. 30Â°W, which is in the middle of the Atlantic Ocean, is an angular distance of 30Â° west of the Prime Meridian.
Unlike latitude lines, longitude lines are not parallel. Meridians meet at the poles and are widest apart at the equator. Zero degrees longitude (0Â°) is called the prime meridian. The degrees of longitude run 180Â° east and 180Â° west from the prime meridian. geographic coordinates. Latitude and longitude lines form an imaginary grid over the Earth's surface.
