AvMap Ultra EFIS
Side Slip Indicator is shown with a standard ball indicator. The ball centered on the
inner markers corresponds to the aircraft not side slipping.
Heading is shown in degrees with respect to Magnetic North or True North. The Ultra
EFIS contains an internal world magnetic model that allows it to calculate the local
magnetic deviation and dip. A vertical card compass is also displayed for fast heading
reference.
Note: in the SETUP menu you can choose reference with respect to Magnetic North or
True North.
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.
Transponder information is shown on the PFD screen only if the Ultra EFIS is
connected to compatible transponder. Ultra EFIS is compatible with Micro Air T2000
Transponder. Both the transponder code and mode are shown, with four octal digits
for the code, and one letter for the mode (S for standby, A for mode Alfa –no altitude
encoding-, and C for mode Charlie –with altitude encoding-). The Ultra EFIS acts also
as an altitude encoder, so no additional altitude encoder is necessary.
QNH Setting
When the Ultra EFIS is in Primary Flight Display mode the pressure reference for the
altimeter can be selected by pushing the rotation knob.
Select QNH to enter the QNH menu.
Select BARO to set the standard atmosphere: QNH value is equal to 1013,25 hPa or
29.92 inch of mercury.
Select MAN to set manually local air pressure at mean sea level (QNH value).
Aircraft Specific V-Speed reference values
Set the aircraft specific V-speed values to get the right information on the air speed
ranges bar.
Refer to the aircraft operating manual to find the correct values of your aircraft.
To change V-speed reference values go to the Setup display mode by pressing the
rotation knob for 5 seconds.
Select SETUP to enter the Setup menu and select SPEEDS to enter the V-Speed
reference values shown on the bottom of the SETUP display mode.
Rotate the rotation knob to change values and push the rotation knob to confirm.
