System description
The typical Instrument configuration consists of following instruments:
• Horis Kanardia - AD-AHRS standalone unit with artificial horizon and air data source;
• DAQU engine monitoring box (mounted behind instrument panel);
• Engine data display;
• IAS indicator - 80 mm (3 1/8“);
• Altimeter - 80 mm (3 1/8“);
• Variometer - 57 mm (2¼”);
• RPM and hour meter - 57 mm (2¼”).
All instruments are electronic devices connected to the main system electrical bus. They have a
familiar needle display recognized immediately by older pilots as well as large digital numbers
which are easy to read in all conditions. The only unit which is connected to the airplane Pitot
and Static source is Horis Kanardia.
1 Horis Kanardia
Horis is an electronic device. It consists of a
set of sensors and an LCD display. Majority
of sensors are built into its compact hous-
ing: static pressure, dynamic pressure, 3
axis ac-celerometer, 3 axis angular rate and
GPS receiver. Only GPS antenna and OAT
sensor are externally mounted. All sensors
are solid state - there are no moving parts,
which means less problems with fatigue
and aging.
Horis has two processors: sensor processor
and display processor. The sensor proces-
sor reads sensors and calculates airdata, at-
titude, GPS and other values using special
sensor fusion algorithms. These values are
passed to CAN bus where other CAN devic-
es may use also them. The display proces-
sor monitors the CAN bus and it displays
the information on LCD display.
One push/rotate knob is used for the oper-
ations. User interface is optimized so only
minimal interaction is required to operate
the instrument.
Safety Instructions!
Keep the unit powered during flight, otherwise engine data and air
data will be lost from the displays until power is re-applied.
