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.
Senior Fellow in Electrical Engineering. The longitude of a point on earth is the angle, east or west, between that point. and a certain reference line on the earth. If you take a globe or a map and draw a line through all the points that have. exactly the same longitude, the line you get is the meridian of that longitude.The reference line is the meridian of zero longitude, called the Prime Meridian.atitude is the angle north or south between a place and the equator. Longitude is the angle east or west between the same place and the Prime Meridian. With only those two numbers, you can nail down any point on the Earth. 1 person found this useful.
