User manual

10 InfoBox Reference
Infobox data types are grouped into logical categories.
All InfoBoxes display their data in user-specified units. Where
data is invalid, the displayed value will be ’—’. This happens, for
example, when no terrain data is found or it is not in range for the
Terrain Elevation infobox type.
In the following description of the infobox data types, the first title
is as it appears in the infobox configuration dialog box, the second
title is the label used in the infobox title. Note that these labels
have changed since older versions (pre V4.2) of XCSoar.
10.1 Altitude
Height GPS
H GPS
This is the height above mean sea level reported by the GPS.
Touchscreen/PC only: in simulation mode, this value is ad-
justable with the up/down arrow keys, and the right/left arrow
keys also cause the glider to turn.
Height AGL
H AGL
This is the navigation altitude minus the terrain height obtained
from the terrain file. The value is coloured red when the glider
is below the terrain safety clearance height.
Terrain Elevation
H Gnd
This is the elevation of the terrain above mean sea level ob-
tained from the terrain file, at the current GPS location.
Pressure Altitude
H Baro
This is the barometric altitude obtained from a GPS equipped
with pressure sensor, or a supported external intelligent vario.
10.2 Aircraft state
Bearing
Bearing
True bearing of the next waypoint. For AAT tasks, this is the
true bearing to the target within the AAT sector.
Speed ground
V Gnd
Ground speed measured by the GPS. If this infobox is active in
simulation mode, pressing the up and down arrows adjusts the
speed, and left and right turn the glider.
