7 Flying with the LXNAV V3
To get the best out of the LXNAV V3 it is important that some preparation is done prior to
take-off. Trying to configure the instrument or set a task while flying is very hazardous
especially in a competition. At the least, it could spoil your whole day! Pre-flight preparation
will ensure that the flight will be both safe and enjoyable.
7.1 On the Ground
7.1.1 Power on Procedure
Press the push button. LXNAV V3 welcome screen will appear. The first screen shows the
version of the boot loader, firmware, hardware and serial number. The boot procedure
normally takes few seconds. When completed, Set Elevation dialogue is shown.
7.1.2 Set Elevation and QNH
This setting is crucial for final glide calculation: therefore pay careful attention to it.
LXNAV V3 can’t calculate final glide.
The instrument will offer elevation over standard pressure level QNE. Use the knob to fine-
tune the elevation.
7.1.3 Pre-flight Check
After elevation setup the LXNAV V3 will switch to normal operation mode.
It is recommended that the MacCready, ballast and bugs settings be set to match the
current glider configuration. Press the push button. The dialogue for MacCready, Ballast
and Bugs will appear.
