Map and Plane (Plane symbol)

The plane symbol shows the current position and direction on the map. It will always be
automatically added and deleted together with the map.
Plane has two different position settings. Symbol is placed in one position when map
orientation is North up, East up, South up or West up and in the other position when current
orientation is Track up, Goal up or Heading up. Depending on settings, position of plane can
automatically change when circling.
There are several representations of plane available. Change style to select different plane
symbol. You can also add a wind vector, which will rotate around the symbol. Enable it by
checking "Show wind" property.

Final glide symbol

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. In the above example the glider is below
the glide path. Chevrons show the position relative to the required glide path in percent.
One arrow means 5% above or below final glide. The middle number is the current
MacCready setting. In task mode it is prefixed with the letter T, A, B, G, S or AG. See
chapter 7.2.1 for detailed explanation of this mode. Sometimes there will be another
number above MacCready which is used for arrival over terrain. If we are on final glide to a
