5.1.1.1 QNH
Using this feature it is possible to offset the altitude datum, which could have changed due
to pressure changes during the flight. As changing the QNH influences the indicated altitude,
care should be taken when changing the value as an incorrect setting can upset the final
glide calculation.
5.1.1.2 Safety altitude
This setting is the altitude reserve or safety altitude, and is the height that the instrument
adds to the final glide altitude required so that the glider arrives over the final glide
destination at the selected safety altitude. After safety altitude input, the pilot has to keep
final glide indicator on 0 to arrive on safety altitude.
5.1.1.3 Magnetic variation
LX8000 has a built in an Earth magnetic field model. If check Auto variation is selected, then
magnetic variation is derived from this model, otherwise user can enter custom value.
5.1.1.4 ETA/ETE calculation based on.
In changing this value you may choose from four different ways to calculate estimated time
of arrival to the navigational point. Calculation is always divided into straight flight and climb
time calculations.
• MacCready setting uses the Polar data and MacCready setting to calculate speed to fly
and climb rate.
• Vario uses the last four thermals average to compute climb rate and uses this value to
calculate speed to fly.
