position from where you will achieve the final glide with current altitude and 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°.
In the lower left corner of 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 direction relative to
the map orientation. Wind direction and wind speed are numerically presented below 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 bottom right corner of screen. A distance of drawn zoom symbol
is plotted above the scale. If there is a letter “a” written next to distance scale, it means,
scale of map will automatically adapt to 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 also 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.
