Page 61 of 85
The instrument will offer elevation from terrain database, based on current latitude and
longitude. Elevation will mostly be within few meters from current elevation. Use bottom-
right knob to fine tune elevation.
If elevation is not known and QNH pressure is known, you should NOT press button QNH.
Just keep turning bottom-right knob (PAGE selector) and look at QNH value to adjust it to
proper value.
QNH button should be pressed 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.
Profile selection dialog and Elevation dialog are not shown if LX8000 is switched
off and on during flying.
7.1.4 Preflight check
After elevation setup, LX8000 will get in airport mode. It will take about 30seconds to draw
map screen for first time. All waypoint files and databases are loaded at that time and
therefore instrument might react a little bit slowly.
It is recommended to check MacCready, ballast and bugs settings to match current glider
configuration. Press MC/BAL button. Dialog for MacCready, Ballast and bugs will be shown.
Use bottom-right knob to modify MacCready setting. See chapter 5.5.5.2 for more details
It is also highly recommended to check safety altitude setting. See chapter 5.1.1 to find out
how to setup safety altitude.
7.1.5 Preparing a task
While it is advisable to prepare the task properly before taking off and thus avoid mistakes
made in haste, all the following actions, except task in not going to be declared, can also be
done during flight.
