The bearing is the direction (according to the system described above) to a selected
waypoint seen from the viewer.
Caution
: Track or Tracklog is also called the sequence of recorded positions during one
flight.
2.6.4 Waypoints
and Co-ordinates
A waypoint is any single point on the earth’s surface that you would like to go to.
The FLYTEC 6030 GPS can save up to 200 different waypoints. Each waypoint can have up
to 17 characters, e.g.
“Fiesch Airfield”.
In determining the waypoint, it is also necessary
to enter the altitude, i.e. “1123” meters (always above sea level). We now only need the
position of waypoint on the earth’s surface. For this purpose the FLYTEC 6030 GPS utilizes
the most international and commonly used geographical map system named WGS84
(World Geodetic System 1984). This reference system assumes that latitude is measured
from the equator (0 degrees) to the North Pole, 90 degrees North, and to the South Pole
- 90 degrees South. Longitude is measured from the Greenwich zero meridian ( near London),
East is counted positive and West is negative up to +/-180°.
Setting of coordinates is also possible in UTM and Swiss Grid. The FLYTEC 6030 GPS also
understands waypoints entered according to the previous norm, introduced by Flytec:
3 letters and 3 numbers.
Example: FIE112 indicates a waypoint with the name FIExxx
and an altitude of 1120 meters above sea level.
In
Basic Settings / Coordinate Format the data entry format is selectable between:
1) Degrees Minutes Decimal places of minutes (dd°mm.mmm)
2) Degrees Minutes Seconds (dd°mm’ss”)
3) Degrees Decimal places of degrees (dd.ddddd)
4) UTM ( a grid with a 1km raster in both and N-S and in E-W direction )
5) Swiss Grid
Basically one should always try to use No. 1) (=factory setting) because only this format is
using exactly the same calculation format as the GPS receivers do. With all the other formats
rounding errors could sum up to 20 m.
