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 measured from the Prime Meridian (which is the longitude that runs through Greenwich, England), with positive values going east (0 to 180) and negative values going west (0 to -180). So, for example, 65 degrees west longitude, 45 degrees north latitude is -65 degrees longitude, +45 degrees latitude.
