Attitude Calculation
The AF-5000 artificial horizon display (attitude) is generated via a complex algorithm using a multitude of sensors as
described in Table 2. In normal operation an AF-5000 uses airspeed to provide superior attitude accuracy. Should
airspeed become unavailable due to inadvertent blockage of the pitot system, GPS ground speed will be used as an
attitude aid.
GPS ASSIST
will be annunciated on the PFD when this mode is in effect.
Compass Accuracy Effects on Synthetic Vision, Map Performance, and Autopilot
It is critical that the magnetic heading be as accurate as possible for optimal Synthetic Vision and Moving Map
performance. The SV-ADAHRS-20X
–
and SV-MAG-236 if included in the system
–
must be installed correctly, calibrated,
and operating well
in all attitudes
. However, it is important to note that magnetic heading is not used to aid attitude
determination under any circumstance.
GPS Receivers
–
SV-GPS-250 and SV-GPS-2020
The SV-GPS-250 and SV-GPS-2020 GPS modules are externally mounted GPS receivers designed specifically for use with
AF-5000 systems. Both modules are powered by the AF-5000 display (and thus will provide position updates when the
AF-5000 display is operating on battery backup power). Each module outputs GPS data to AF-5000 in NMEA format and
automatically sets the time on the AF-5000 display. To improve positional accuracy, both the SV-GPS-250 and the SV-
GPS-2020 receive Wide Area Augmentation System (WAAS) GPS correction signals (where WAAS is available).
The ability
to receive WAAS GPS correction signals does not allow the SV-GPS-250 or SV-GPS-2020 to be used as a primary
navigation source in an IFR environment where a TSO’d WAAS GPS may
be required.
Engine Data Modules
–
SV-EMS-220 and SV-EMS-221
The engine gauges on your AF-5000 Engine Page are generated from the data acquired by the SV-EMS-220 or SV-EMS-
221 Engine Monitoring module and their connected sensors. These modules support popular four and six-cylinder
engine installations and can measure a variety of engine and environmental parameters such as RPM, manifold
pressure, oil temperature and pressure, exhaust gas temperature (EGT), cylinder head temperature (CHT), fuel levels for
multiple tanks, voltage, current, fuel pressure, fuel flow, carburetor air temperature, coolant pressure and temperature,
flap and trim potentiometers, external contacts, and general purpose temperature sensors.
