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.
Longitude is an imaginary line that runs from the North Pole to the South Pole and is used to describe the location of a place on Earth east or west of the zero or prime meridian. In 1884, the International Meridian Conference adopted the Greenwich Meridian as the universal prime meridian or zero point of longitude.
