UAV-1004234-001, AV-30-E Installation Manual 25
Rev H
Each AV-30 must have a dedicated, properly labeled, pilot resettable
circuit breaker as part of the installation. Power for the unit should be
supplied from the main battery master relay. It is recommended to shield
the power wire.
9.2.2 Pitot and Static Interfaces (Required)
Pitot and static connections are required for DG, AI, and MFD mode.
Airspeed, altitude, derived angle of attack (AoA), True Airspeed (TAS),
Density Altitude (DALT), DG heading, and traffic altitude all require pitot
and static connections as they are based on either altitude or airspeed
measured from those connections.
When the AV-30 is installed as a DG, the pitot and static connections
must be connected for correct functioning of Outside Air Temperature
(OAT), backup battery in flight, and DG heading aid. ALT, BARO,
Vertical Speed (VS), TAS, and DALT are the air-data related parameters
that can be displayed when in DG mode.
When the AV-30 is installed as an MFD, the pitot and static connections
are required for traffic relative altitude. If unconnected, incorrect relative
altitudes may be displayed.
Pitot and static data also aids the attitude algorithm, using a feature
called speed assist.
9.2.3 Outside Air Temp Input (Optional)
The optional outside air temperature interface requires a dedicated
external analog probe. This port connection is compatible with the
Davtron P/N C307PS (not supplied).
This is a differential two-wire current source based on the Analog
Devices AD590KH component and supplies a current that corresponds
to the ambient temperature.
