ADAHRS
The core of the Ultra is the ADAHRS module. The ADAHRS module contains
solid-state gyros, accelerometers, magnetic eld sensors and air data
sensors, providing attitude, heading, altitude and airspeed data to the system.
In order to take full advantage of its functionality, the Pitot and Static ports should be
connected to the aircraft Pitot-static system.
GPS receiver
Connecting the external GPS receiver to the Ultra, the system provides the pilot with
navigation information on the HSI page , providing its position, direction and radials relative
to reference navigation points.
Preloaded navigation POI’s
Ultra is preloaded with Jeppesen navigation POI’s: Airports, NDB’s and VOR’s.
Coverage available: Europe-Africa, North America, South America, Asia-Australia.

2. Installation
The installation procedure is divided in the following steps:
• Location
• Mechanical installation
• Connections & wiring
2.1 Location
The Ultra is designed to be installed on the aircrafts instrument panel.
It is assumed that the instrument panel is completely perpendicular to the level and straight
ight attitude.
In case the instrument panel is rotated the simple horizon alignment calibration procedure
is required.
Note: For calibration see Chapter 3.
IMPORTANT: The Ultra contains a magnetometer and other precision electrical sensors.
The location selected for installation should be clear of strong magnetic or electromagnetic
disturbances as much as possible. Avoid installing the Ultra near electronic equipment (other
digital EFIS, radios, transponders, etc), AC or variable DC cables, alternators, electrical
motors, ferrous materials, etc. In such cases the proper behaviour of the compass is not
guaranteed (i.e. the compass may be crossed as “out of order” or may give erroneous
indications).
Hint: use a hand-held compass to verify the magnetic disturbance in the area selected for
installation. If the needle shows relevant changes or unstable indication, the location is not
suitable for installation. Make sure to perform this test with all on-board electronic devices
switched ON.
2.2 Mechanical installation
Make sure you have enough space on the front and behind the cockpit panel to install the
Ultra. Check the Ultra measurements on Figure 2.
Ultra is designed to be installed in a standard 3 1/8” (79,5 mm) diameter hole.
6 - User and Installation Manual
AvMap Ultra EFIS
The instrument has to be installed from the front of the panel and screwed from behind the
panel according to Figure 3.
Figure 2
77,5 mm (3.05”)
The screw length that need to be used for panel installation depend on the panel thickness
and is based on the following formula:
5mm ≤ l - t ≤ 8mm
l = length of the screw
t = thickness of the panel
Use the screws and metal washer included in the box for standard panel thickness of up to 3mm. For
thicker instrument panels, use longer screws and use the formula to choose the right screw length.

IMPORTANT: Make sure you respect the screw length formula to avoid damaging the
plastic of the Ultra. Use light thread locker to prevent screw loosening with vibration.
Use the Cutting template, included in the box, to cut out the panel. (see Figure 4)

Connection to the Pitot-static system
In order to display accurate speed and altitude data the Ultra needs to be connected to the
aircraft Pitot-static system. The Pitot and static ports on the back of the Ultra are equipped with
1/8” NPT female ttings. To connect the aircraft Pitot and static lines to the Ultra, you must use
standard 1/8” NPT male ttings at the end of each of the lines. Installation along with other
mechanical or digital altimeters and airspeed indicators is supported by mean of a T coupler
(not included in the Ultra box).

2.3 Connections & wiring
On the back of the unit there are 4 connectors: the Pitot port, the static port, the power supply

AvMap Ultra EFIS
Connect the Pitot line to the port labeled
PITOT and the static line to the port labeled
STATIC.
IMPORTANT: Use 2 wrenches to screw
the NPT male tting into the NPT female
tting. Use the rst wrench (14mm or 9/16
inch) to hold the female tting on its place,
and the second key to screw the male tting
into the female one. Screw carefully until
the ttings get tight but avoid overtightening
(see Figure 7).
IMPORTANT: Use exible plastic tubes and make sure the tubes t tight on the NPT Pitot
and static ports and can not get loose due to vibration.
IMPORTANT: We recommend to test the Pitot-static system for leakage after any alteration.
External GPS receiver connection
Connect the external GPS receiver, included in the box, on the back side of the Ultra to the
GPS port as shown on Figure 5.
The GPS receiver comes with a 1,5 meter cable and is designed for use inside the aircraft.
Note: an additional gps extension cable of 2 meter is available at the AvMap dealer and
AvMap webshop.
The GPS receiver can be mounted to any convenient surface that has a clear view of the
sky. It can be mounted on the aircraft’s dashboard using the included Velcro strip. The GPS
receiver must have a clear view of the sky in order to receive satellite signals. GPS uses “line
of sight” signals to locate and track satellites.
If the signals are obstructed by dense objects such as aluminum, steel or even heavy ice,
the Ultra will not operate properly. Signals may also be blocked by heated wind screens
(breglass, plexiglass and other plastics are normally transparent to GPS signals). If you
nd that the Ultra does not locate GPS FIX quickly or consistently, moving the location of the
GPS receiver a few inches often provides a better view of the sky.
Power supply
IMPORTANT: Power the Ultra from an 10 to 35 Vdc supply. Mount on the power wire
(RED) the 1A fuse holder, provided in the box, to protect against short circuits.
Serial Connection
Ultra EFIS comes with two RS232 serial connections, both can be enabled for sending out
NMEA messages to external devices (see Figure 5):
Connect the Ultra serial TX wire to serial RX wire of the external device.
Connect the Ultra ground (GND) wire to the ground (GND) wire of the external device.
Note: The Ultra is not enabled to receive data through serial, therefore the Ultra serial RX

Note: See paragraph 4.5 for NMEA-OUT settings.
3. System Calibration
There are three types of calibration procedures;
1. Horizon alignment calibration
2. Compass calibration
3. Altimeter calibration
3.1 Horizon alignment calibration (AHRS)
Scenario A – Horizon alignment calibration NOT required
It is assumed that the Ultra is installed in an instrument panel that is completely
perpendicular compared to the level & straight ight attitude and aligned with the lateral
axis of the airplane.
In this case no horizon alignment calibration is needed.
Scenario B - horizon alignment calibration required
In case the Ultra is installed in an instrument panel that is aligned with the aircraft lateral
axis, but not perpendicular to the straight & level ight attitude, the simple horizon alignment
calibration procedure must be executed.
Note: The horizon calibration corrects also a roll oset, if it is not perfectly alligned with the
aircraft laterall axis.
Horizon alignment calibration procedure
Execute this calibration procedure to align the horizon line of the Ultra with the aircrafts
straight & level ight attitude.
The procedure can be performed on the ground or in ight (with 2 people on board). The
Ultra must be powered since at least 2 minutes before processing the calibration. When
performing the calibration the ground, set the aircraft in level and straight ight attitude by
using jacks or blocks (or by asking a friend to push or lift the tail and hold). If its known that
the aircraft ies in “x” degrees ‘nose high’ straight and level ight, a digital level can be used
to orient the aircraft to normal ight attitude prior to the calibration. It is possible to perform
