The segment of a route currently being travelled.
The current elevation above sea level.
Bearing. The compass direction from your position
to a destination, measured to the nearest degree.
Course Deviation Indicator. A graphical representa-
tion of your position relative to your planned course,
giving you an indication of how far left or right of the
planned course you are and how to get to the
destination.
Course Over Ground. The direction the receiver is
moving. COG can be reported in true or magnetic
north values.
A unique numeric or alphanumeric description of the
position.
Course to Steer. The direction you should be
travelling in order to return to the course while
proceeding towards the destination. It is a "compro-
mise" course bearing that projects from your current
position to a point on the courseline mid-way
between a point perpendicular to your position and
the current leg destination waypoint.
Refers to the theoretical mathematical model of the
earth's sea level surface. Map makers may use a
different model to chart their maps, so position
coordinates will differ from one datum to another.
The datum for the map you are using can be found in
the legend of the map.
