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.
Lesson Summary. Latitude is the angular distance of a place north or south of the Equator in degrees. A latitude of zero degrees is on the Equator of the Earth. Ninety degrees north is the North Pole, and 90 degrees south is the South Pole. Longitude is the angular distance of a place east or west of the meridian at Greenwich, England. With these two numbers, any point on the Earth's surface can be located.
