Apollo 65 - Manual (Page 304)

Bearing (BRG): The direction to any point, usually
measured in degrees relative to true or magnetic
north. The direction from your present position to
your destination waypoint.
C CF: Final approach course Fix. This waypoint type is
used when necessary to define a course to the FAF -
all VOR DME approaches require a course fix
waypoint. A code appended to a waypoint in the
database that may not appear on a published map.
Circular Error Probable (CEP): As applied to GPS
position fix accuracy, the radius of a circle inside of
which there exists a 50 percent chance of being
located.
Constellation: A group of stars or objects, such as
GPS satellites, in the heavens.
Coordinates: Values for latitude and longitude that
describe a geographical point on the surface of the
earth.
Course: The planned direction of travel in a
horizontal plane.
Course Deviation: A measurement of distance left or
right from the desired course of travel.
Course Deviation Indicator (CDI): A graphic
indicator of course deviation typically shown as a
graduated horizontal bar with an icon indicating the
deviation distance left or right of course.
Course Intercept: Similar to an arrival alert, arrival is
related to a course or radial to a point. When flying an
arc during an approach, the arrival alert is issued
when the aircraft is 1 nm/100 kts of intercepting the
inbound course. When Vector to Final is selected, or
you are executing a procedure turn at the FAF, the
course intercept alert occurs when the aircraft has a
Track Angle Error
£45° and the cross track deviation
is
£ 1 nm.
