ALT
(GPS Altitude): Altitude, calculated by the GPS receiver. A substantial
difference between this altitude value and altitude referenced above sea
level may exist due to accuracy degradation by the military; altitude
information should not be used for vertical navigation.
Azimuth
:
Bearing, as measured clockwise from true or magnetic north.
Brg
(Bearing):
The direction to any point, usually measured in 360
degrees relative to true or magnetic north.
Course
:
The planned direction of travel in a horizontal plane.
Course Deviation
:
The amount of distance left or right from the
desired course of travel.
CDI
(Course Deviation Indicator
): Is the graphic indicator of course
deviation shown as a graduated bar indicating the distance left or right of
course.
DTK
(Desired Track):
The desired course of navigation between a point
of origin and a destination Waypoint.
GES
(Ground Earth Station):
The ground earth station links with the
ORBCOMM satellite to provide a direct link to the ORBCOMM Network
Control center.
GS
(Ground Speed):
Speed of travel across the ground measured in
nautical miles per hour.
INT
(Intersection):
Intersections can be set to display, or not display in
the moving map mode according to their distance from the aircraft.
Kts
(Knots):
All speeds are displayed as knots or nautical miles per hour.
Every 1.15 statute miles per hour equals 1 knot.
Lat
(Latitude):
Lines that circle, and are parallel to, the equator.
Latitude is in degrees, minutes and seconds north and south of the
equator.
LEO
(Low Earth Orbit):
A new generation of satellite communication
satellites orbiting at low altitude (approximately 500 miles above the
earth), able to communicate with low power ground transceivers without
the need for a directional antenna. All two-way data is transferred via
ORBCOMM’s Low Earth Orbit constellation.
Lon
(Longitude):
Any line from pole to pole measured in degrees,
minutes and seconds that is perpendicular to the equator
.
METAR
: the international standard code for hourly and special surface
weather observations. The METAR acronym roughly translates from the
French as Aviation Routine Weather Report.
