AvMap Ultra EFIS
Course over Ground (COG) is shown on the compass instead of heading in case the
magnetometer is not calibrated or when the magnetometer has an failure. The COG
data is based on GPS source.
Note: If the compass source is GPS, the device shows "COG" aside the compass. If
the compass source is the magnetometer, the device shows "HDG" aside the compass.
Both can be shown in reference to Magnetic North or True North.
Current Position is shown in latitude/longitude format. The Ultra EFIS can calculate
position even in the absence of GPS. In absence of GPS fix the position indicator
change in RED.
Wind data is approximated and displayed by the system when suitable GPS,
compass and IAS data are available. Wind direction is referred to the direction where
the wind is coming from.
Note: The speed units selected in the SETUP menu are also applied to wind speed.
Note: Without Magnetometer calibration (see Chapter 3) wind data are not available.
GS (Ground Speed). The Ultra EFIS can calculate ground speed even in the absence
of GPS, with degraded quality; this is indicated by a change in colour (RED) in the
ground speed indicator.
Note: In the SETUP menu select your preference unit for speeds: knots, kph, mph or
m/s.
ADF (Automatic Direction Finder) is shown with a standard double line needle in
green color. The ADF info box of the point-of-interest (POI) used to calculate distance
and direction is shown in the bottom right corner. The ADF info box displayed includes
the POI ID, distance (in nm, km or miles), POI name, and two lines of miscellaneous
textual information (frequencies and runways for airports, for example).
HSI (Horizontal Situation Indicator) is shown with a standard single line needle in
yellow colour. The HSI indicator is complete, with course deviation indicator (CDI) and
to/from flag. The HSI info box of the point-of-interest (POI) used to calculate distance
and direction is shown in the bottom left corner. The HSI info box displayed includes the
POI ID, distance (in nm, km or miles), POI name, and two lines of miscellaneous textual
information (frequencies and runways for airports, for example).
HSI settings
When the Ultra EFIS is in HSI display mode press the rotation knob to enter the HSI
mode menu.
Select HSI to enter the HSI menu:
In the HSI menu you can select an Airport (ARPT), VOR and NDB as your navigation
point.
Select CDI to setup the course deviation indicator on the HSI indicator. Use the rotation
knob to change CDI.
