7 Flying with the LXNAV V7
To get the best out of the LXNAV V7 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 V7 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.
The instrument will offer elevation over standard pressure level QNE. Use the knob to fine-
tune the elevation.
The QNH should be changed only when airfield elevation and QNH pressure are given. This
might happened on some competitions.
In all other cases elevation should always match QNH pressure.
The Set Elevation dialogues are not shown if the LXNAV V7 is switched off and on
during flying. Dialogue will also quit after 15 seconds if pilot does not do
anything.
