than a minute to determine the location. Buildings, mountains or thick forest affect reception
quality. Therefore, you should always look for the best possible visibility around you and the
antenna under the Flytec 5030 GPS label should point upwards. When the units is fastened,
it should not have more than 45° deviation from a horizontal position.
Because the receiving strength of the satellite signal is only 1/1000 of mobile radios, these
radio receivers and other disruptive factors (like notebooks) should be kept as far away as
possible from the Flytec 5030 GPS.
Together with the navigation signal, information about the number of received satellites is
shown on the right side of the bar scale. The value for the reception quality is determined by
the length of the bar. The longer the bar, the more precise is the reception.

2.2 Compass and Flight Direction
In contrast to a normal magnetic compass which is oriented to magnetic north, the GPS
compass can show direction only when the user moves about. However, it has the
advantage that it is not subject to any grid deviation and does not show any deviation as a
result of iron or any magnetic material either. Its zero point always corresponds with true
geographic north (0 or 360 degrees). The course that is the flight direction (= Track), is
calculated from your movements.
If the user remains stationary at the same location, then the course and compass needles
are inoperative. The exact course (that is the direction in which the user travels over ground)
is always at the top of the compass, but can also be read in the display “Track”. When
circling in a thermal the compass rose appears to turn; in reality the needle does not move;
the unit along with the aircraft, moves around the rose.
2.3 Ground-Speed
The GPS receiver fixes its position once every second. Speed over ground is derived from
the distance between these positions. Only from the difference between airspeed and
groundspeed can one make conclusions about the wind's influence, and ultimately these are
the most important pieces of information a pilot needs during flight. The ground speed
should appear at all times in an user selected field.
With a paraglider Flytec 5030 GPS (without a pitot sensor), the GPS speed is shown
automatically in the large analogue and digital scales if no vane sensor is plugged in. The
same applies when in the Basic Settings /Air Speed correct pitot, the function of the pitot has
been deactivated. (Use sensor? = No )
In this case it is possible to use a calculated airspeed in a user selectable field. This issue is
calculated by a vector operation of ground speed and wind.
