Vario
Window
The
Vario
Window
or
or
or
is
found
near
the
center
of
the
lower
edge
of
the
moving
map
window.
It
can
display
several
variometer
values
and
is
also
used
to
display
local
time
and
set
the
UTC
time
offset
and

Vario
Window
Display
Options
The
display
options
shown
below
are
displayed
in
the
climb
units
selected
in
the
setup
menus
–
such
as
knots
or
m/s.
•
Climb/Glide
Netto
This
setting
will
display
the
Glide
Netto
while
cruising
between
thermals
and
the
Climb
Rate
in
This
Thermal
while
thermalling.
The
ClearNav
switches
between
the
2
numbers
automatically
as
you
change
flight
modes
–
such
as
changing
from
Cruise
to
Climb
mode
or
vice
versa.
There
is
a
delay
of
a
few
seconds
as
you
transition
between
flight
modes
because
it
takes
a
few
seconds
for
the
ClearNav
to
determine
that
you
have
changed
flight
modes.
Climb
Rate
in
This
Thermal
This
is
the
average
climb
rate
achieved
in
the
current
thermal.
Glide
Netto
This
is
the
average
netto
climb
or
sink
achieved
in
the
current
glide.
The
term
“netto”
indicates
that
the
sink
rate
at
the
current
speed
from
glider’s
polar
is
added
to
the
raw
vario
number
so
that
the
displayed
number
shows
what
the
airmass
is
doing
rather
than
the
combination
of
airmass
motion
and
glider
sink
rate.
A
value
of
zero
indicates
that
the
glide
has
(on
average)
been
done
in
still
air.
A
positive
value
indicates
that
the
glide
has
been
done
(on
average)
in
rising
air.
A
negative
number
indicates
that
the
glide
has
been
done
(on
average)
in
sinking
air.
Theoretically,
you
will
slow
down
in
lift
and
speed
up
in
sink
and
should
be
able
to
get
a
positive
