Task declaration process

The task declaration process is fully automatic and doesn't need any pilot interaction. Actual task and
pilot data will be written into both flight recorders immediately after selection. The declaration data will not
change during flight, even if task data will change due to select or edit process (IGC rule). The action is
accompanied by a message on the display.

11.2 During flight

The Zeus HW and SW concept is so far optimized that
pilot doesn't spend too much time to operate the unit
during flight. It is important to point out that there are
many short cuts, which enable direct and fast access to
most important functions. The pilot isn't obliged to
terminate edit process until end due to Auto close
feature, which closes the process after some seconds of
no active commands. A very significant indication that
shows that the unit has changed to flying mode is Log
Book replacement with statistics page after pressing on
STAT button.

Set MacCready, Ballast, Bugs and QNH

After short press on VARIO button a new window will
appear – MacCready. The menu will give options, to
adjust MacCready, Ballast, Bugs and QNH. Setting
MacCready, Ballast and Bugs will have affect on the
glider polar: MC speed, sink speed, cruise speed and
also the efficiency will change.
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 actual QNH value of the airport
where he will take off. This action should be carried out
on ground, after take off the menu will not open any
more. After input of QNH on ground the pilot will be able
to adjust altitude reading during flight, if QNH will change.

Note!
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 neglected.
