The TAS Processor shall also select "proximate traffic" and "other traffic"
intruders to be displayed on the basis of their altitude relative to own aircraft.
The "other traffic" intruders are those that do not qualify to be TA or proximate
traffic but are displayed.
Optional (The TAS Processor may be controlled using discrete inputs).
C. Options
1. Display Option
TSO C151a-class B does not require a display for terrain data, however, if at
all possible, terrain data should be displayed for the aircraft operator. The ter-
rain display greatly improves situational awareness. The EGPWS supports
numerous displays including traditional Radar displays as well as mode mod-
ern MFD's.
Installations, which include a display, will also need to provide the EGPWS
with range data via ARINC 429 format.
2. Altitude Monitor Option
The EGPWS has the ability to monitor altitude sources and provide caution-
ary messages should an altitude source be suspected of being in error. This
feature compares barometric altitude with GPS altitude and generates a
"Check Altitude" message when an error is detected. This is a highly recom-
mended option, which can alert a pilot to problems such as a stuck altimeter
or plugged static port. This option requires no additional hardware and is
enabled during the system installation by programming the configuration
module. This feature can provide both audio and display messages.
3. Outside Air Temperature (OAT) (Recommended)
The EGPWS supports an OAT probe for aircraft operated in cold environ-
ments. Very cold air temperatures cause an increase in the density of the air
mass and can result in barometric altimeter errors, both in sensitive altime-
ters/encoders and blind encoders. Aircraft normally operated in very cold cli-
mates can benefit from the addition of an OAT probe interfaced to the
EGPWS. If the aircraft is equipped with an Air Data Computer which outputs
Digital data with Corrected Altitude on an ARINC 429 port, this can be used
instead of an encoder and external OAT Probe. OAT is programmed into the
configuration module during system installation.
