Xm Weather (Wx) Data System - Lancair Columbia 400 Information Manual

Section 7
Columbia 400 (LC41-550FG) Description of the Airplane and Systems
In case of a CO alert, the red annunciator will illuminate continuously and the aural warning will
state "Carbon Monoxide" every two seconds. The visual alert will remain until the CO level is
again reduced below the alert level. The aural warning may be silenced by pressing the ACK
button on the annunciator panel. The indicator is automatically reset when the CO level drops
below 50 PPM.
On initial power up, the detector goes through a self-test and the annunciator light flashes twice,
but the aural warning will remain off. There will be a three minute warm-up time before the
detector is operational. To test the system any time, press and release the test/reset switch. As on
initial power up, the detector goes through a self-test and the annunciator light will flash twice,
but the aural warning will remain off. To reset the system, press the test/reset switch and assure
that the annunciator light flashes twice. If the detector sensor fails, the annunciator light will
flash every 4 seconds, but the aural warning will not sound.

XM WEATHER (WX) DATA SYSTEM

The system is a one-way communication (receive only) device which receives broadcasts from
XM Satellite Radio, Inc. through one or both of the two geosynchronous satellites which transmit
over the contiguous 48-states of the USA. This system is considered a Line Replaceable Unit
(LRU). Broadcast weather information received by the XM Weather Data System is displayed on
the Avidyne Entegra MFD.
The Wx receiver is a remote mounted "box" which connects to the aircraft's non-essential DC
power bus, the antenna and data port. The Wx Receiver also provides an antenna output for
connection to an XM Digital Audio receiver, if installed.
The tear-drop style antenna receives "line-of-site" transmissions from the satellites. The antenna
consists of a LH circular polarized, hemispherical element with an integrated low noise amplifier
(LNA). This LNA is powered by a +5VDC offset from the receiver through the coax cable.
RYAN MODEL 9900BX TCAD (TRAFFIC AND COLLISION ALERT DEVICE)
General – The Ryan Model 9900BX TCAD is an on-board air traffic display system used to
identify potential collision threats. The TCAD, within defined limits, creates a shield of airspace
around the aircraft, whereby detected traffic cannot penetrate without generating an alert. The
shield size is selectable for various phases of flight, and is adjustable by the pilot. The TCAD
will display multiple aircraft threats. TCAD information is displayed through integration with the
Avidyne Entegra MFD. See Figure 7 - 59 for a schematic of TCAD, TIS, and MFD integration.
The system is comprised of a processor, a transponder coupler, and two antennas (one antenna
mounted to the top of the aircraft and the other mounted to the bottom). The processor is located
on the avionics shelf and the transponder coupler is located behind the instrument panel on the
co-pilots side.
The TCAD monitors the altitude difference and range, and warns the pilot when the calculated
time to closest approach (CPA) of the intruder meets a certain threshold (15 to 30 seconds,
depending on aircraft configuration). The altitude data from the intruder is referenced to pressure
altitude (29.92 inches or 1013mb), as is the onboard encoder. The range is determined using
radar time of arrival technique. Bearing to the traffic is determined using the dual directional
antennas, on the top and bottom of the aircraft.
