Panel What it shows
Go North/East The northerly and easterly distance components of the
bearing to go to the Target. It is given as two Cartesian
distances, with one value representing the north/south
distance and one representing the east/west distance
from the current GPS position to the Target.
Go Up/Down The difference in altitude between the current altitude and
the altitude of the Target. If you are using 2D GPS then
the current altitude used is the value entered in the 2D
altitude field.
Heading Your current direction of travel. The heading is the angle
between the last two GPS positions computed. If you are
stationary or moving very slowly, the heading display
freezes until you start moving again. The heading is
displayed with a ‘T’ if it is relative to true north or an ‘M’ if it
is relative to magnetic north.
Time ThecurrentGPStimeanddate.ThevalueistheGPS
time plus the local variation from GMT, taken from the
‘Time and Date’ setting.
Time to Go The expected time to reach the Target. This value is
calculated from your heading and velocity.
Turn The size and direction of the turn required to head
towards the Target. The arrow indicates whether you
need to veer to the left or to the right, and how big a turn is
required, while the numeric value indicates the angle
between the bearing to the Target and the current
heading.
Velocity Your velocity. It is two-dimensional, taking into account
your horizontal velocity but not your altitude.
