ELEVATION
Altitude above sea level (MSL). Usually refers to field Elevation of an airport. Also refers to a satellite’s height
above the horizon.
above the horizon.
EPHEMERIS DATA
Data on the specific location of a satellite that is collected from that satellite when it is first located and is
periodically updated while the satellite is being tracked. Remains current for up to 2 hours.

ETA
ESTIMATED TIME OF ARRIVAL - The estimated time of day the destination Waypoint will be reached,
based on your current speed and the distance to destination.

FILE
It is collection of information (of the same type) stored on a User C-CARD. Each file must have a unique
name, ideally one that describes its contents. File names are kept in a directory on each User C-CARD.

FP
FLIGHT PLAN - A planned course of travel, with one to twenty-five legs, each with its own origin and destination.
FP LEG
The line connecting two waypoints within a Flight Plan.
FSS
FLIGHT SERVICE STATIONS - Provide pilot briefings en route.
FUEL BURN RATE
Fuel burn rate in a cruise configuration.
GLIDE SLOPE
The desired descent path for Vertical Navigation.
GPS
GLOBAL POSITIONING SYSTEM - A satellite based navigation system operated by the US Department of
Defense. It operates 24 hours a day, 365 days a year under any weather conditions.

GQ
GEOMETRIC QUALITY - A measurement of the geometry of the satellites used to triangulate the position. A
low GQ is inaccurate and generates a GQ warning. Navigation data should be used with caution when the
GQ warning appears.

GREAT CIRCLE
Distance measured along the curved surface of the earth. Over long distances, a Great Circle distance is
more accurate than a Rhumb Line distance measured from a mercator chart.
more accurate than a Rhumb Line distance measured from a mercator chart.
GS
GROUND SPEED - The speed over the ground; can vary from air speed as it is affected by the prevailing winds.
HDG
HEADING - The direction your aircraft is facing, defined as an angle from true or magnetic north.
HDOP
HORIZONTAL DILUTION OF PRECISION - It is the index for position-fixing accuracy. The smaller the
HDOP value, indicates a better position calculation.
HDOP value, indicates a better position calculation.
HOME (mode)
The Home (called also Screen Amplifier) mode is used to keep the fix position within the visible map. The map is
scrolled and redrawn automatically when the fix position is moved. When this mode is active the cursor is hidden.

ICON
A symbol shown on any display as a representation of a Waypoint .
IDENTIFIER
An abbreviated name that is assigned to an airport or navaid. The identifier may be any combination of letters
and numbers, up to five characters in length.

INT
INTERSECTION - A Waypoint defined by any combination of courses or radials between two or more
navaids. Enroute and terminal intersections are part of the EKP-III Database.

LAT
LATITUDE - The distance north or south of the equator, measured in an arc with the equator being 0° and
the poles being 90°.
the poles being 90°.
LON
LONGITUDE - The distance east or west of the Prime Meridian (0°), which intersects Greenwich, England.
The range is 0°–180°E, moving east of 0° and 0°–180°W, moving west of 0°.

LORAN
The Loran chains are groups of transmitting stations that use timed radio pulse transmissions.
MAGNETIC NORTH
The migrating pole where the earth’s magnetic lines converge. The north magnetic pole is some distance
from true north at 76.1°N 100°W.
from true north at 76.1°N 100°W.
MARK
Reference points related to cursor position.
MASK ANGLE
The Elevation (height above the horizon, measured in Degrees) below which the EKP-III will not search for
satellites. The Mask Angle used by the EKP-III is variable. It starts at 8° and under certain conditions, may
drop as low as 0°.

MIN
MINUTE - A unit of measure, equal to1/60th of one Degree of a circle.
MORA
This Minimum Off-Route Altitude provides minimum altitudes for terrain and obstruction clearance within the
section outlined by the Latitude and Longitude lines. Mora values clear all terrain and obstructions by 1,000’
in areas where the highest terrain and obstructions are 5,000’ MSL or lower. Mora values clear all terrain and
obstructions by 2,000’ in areas where the highest terrain and obstructions are 5,000’ MSL or higher. Moras
are not shown where there is no published data.
