current MacCready setting. The yellow rectangle represents the position from where you
will achieve the final glide with current altitude and MacCready zero.
The relative bearing (near the top) gives advice on which direction and how much to turn in
order to fly towards the selected target. In the above example we should turn right 21°
.
I
n the lower
-
left corner of
the
screen a
wind symbol with Thermal assistant
is
displayed.
The thermal assistant continuously analyses the thermal whilst circling. The
sizes of the dots indicate the strength of the thermal.
The arrow indicates the wind
di
rection relative to the map orientation. Wind direction and wind speed are
presented
numerically belo
w the arrow.
The final glide symbol
is a complex symbol.
The bottom number shows your predicted
arrival altitude.
Negative numbers indicate that you are
below the glide path and positive
numbers indicates you are above the glide path.
The middle number is the current
MacCready setting.
Zoom scale
is displayed in
the
bottom
-
right corner of
the
screen.
A distance corresponding
to the
zoom symbol is plotted above the scale.
If there is a letter “a” next to
the
distance
scale it means
that the
scale of map
will automatically
adapt to the
goal.
In the bottom row several items are displayed.
Thermal
shows the last thermal average,
Brg
is the bearing to the selected target,
Dis
is the distance to the target and
Alt
is the
current MSL altitude.
The last two numbers (
reqE
and
E)
show the required glide ratio to the target. In the
above example the required glide ratio is infinitive
and current glide ratio is
a
lso infinitive
.
The current glide ratio
is calculated over the last three
minutes of flight.

Second Navigation Page
The second page is similar to the first page with additional data shown in the bottom line.
The additional items are the current net vertical speed, current track, ground speed, height
above ground and optimised distance.
