AvMap Ultra EFIS
Attitude is displayed with a standard coloured artificial horizon. An aircraft symbol is
used to indicate the aircraft's nose orientation.
A trajectory vector (also called "Flight Path Vector") is displayed with a circle and three
lines; the trajectory vector indicates the aircrafts real path with respect to the horizon and the
aircraft's nose.
Note: it is possible to enable/disable the trajectory vector symbol in the "PREFERENCE"
menu.
Pitch indicator is displayed by markers that are horizontal with the horizon and are
equally divided with 10 degrees pitch of separation between the lines.
Roll indicator is displayed by markers of 10, 20, 30, 45 and 60 degrees of roll.
Indicated Air Speed (IAS) is shown in number representation as well as on
a vertical tape. The tape also displays four coloured lines for operating arcs;
white from the stall speed in dirty configuration (Vs0) to the maximum flap
extension speed (Vfe), green from the stall speed in clean configuration (Vs1) to
the maximum cruise speed (Vno), yellow from the maximum cruise speed (Vno) to the
never to exceed speed (Vne), and red from the never to exceed speed (Vne) and higher.
Note: Aircraft specific V-Speed reference values can be entered in the "SETUP" menu
(see paragraph 4.4).
Note: In the "SETUP" menu select your preference unit for speeds: knots, kph, mph, m/s.
Altitude is shown in number representation as well as on a vertical tape. Underneath the
tape there is a Kollsmann window where the user can adjust the QNH setting.
Note: In the "SETUP" menu select your preference unit for altitude: feet (ft), meter (m).
Note: Due to fluctuations in pressure over time, it is important to periodically calibrate
the altimeter to maintain accurate readings (see paragraph 3.3).
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
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.
