Set Maccready (Mc), Ballast, Bugs And Qnh; Statistics - LX Navigation Zeus User Manual

12.2.1 Set MacCready (MC), Ballast, Bugs and QNH

After a short press on the VARIO button a new window
will appear – MacCready. The menu will give options, to
adjust MacCready (MC), Ballast, Bugs and QNH. Setting
MacCready, Ballast and Bugs will influence the glider polar
and MC speed, sink speed, cruise speed, as well as the
overall efficiency that will also be changed.
Entering a Bugs setting will decrease the efficiency, which
will affect the final glide calculation.
Example:

Efficiency is 30.

Bugs setting is 10%.
Equation: Fbugs = f x (1-bugs [fraction])
= 30 x (1-0.10) =
= 30 x 0.9 = 27
QNH setting:
The pilot should input the actual QNH value of the airport being used for take-off during the initial setup
process. This action should be carried out on the ground; after take off the menu will not open any more.
After input of QNH on the ground the pilot will be able to adjust the altitude reading during flight, if the
QNH changes.

12.2.2 Statistics

The statistics page will open after a press on the STAT button.
The statistics page offers the following statistics data:

Thermal analysis: Two types.

OLC: Calculation of OLC distance, score etc.

Baro: Shows baro trace from take off until present position

Task: Presents task statistics data divided by legs

Route: Shows task and flown distance

Timer: Starts timer
The statistics page colour structure can be adapted to suit a pilot`s personal requirements. This can be
done under: Setup > User Interface > Statistics colours.
If the task consists of more than three legs, use zoom to select legs of interest.
QNH setting doesn't replace setting of
elevation during booting; this should be
carried out every time otherwise the
unit will not switch to navigation mode.
QNH setting isn't obligatory and may be
omitted.
When the task has not been started
yet, the statistics data is limited to
take-off and flight duration.
