Bearing (Search=>Filter=>General)
Use these check boxes to select waypoints based on their bearing from the current centre point. By default, all bearings are selected. Clear the check boxes of those bearings that you want to exclude from the filter. You must select at least one bearing or the filter will fail.
The actual degrees used for the calculation of the bearing is:
0..23 = 'N';
24..67 = 'NE';
68..112 = 'E';
113..157 = 'SE';
158..203 = 'S';
204..247 = 'SW';
248..292 = 'W';
293..337 = 'NW';
338..360 = 'N';
