Failed
Path
Messages
A
‘FAILED
PATH’
message
indicates
that
a
data
path
connected
to
the
GDU
(PFD
or
MFD)
or
the
GIA
63W
(1
or
2)
has
failed.
This
‘FAILED
PATH’
message
is
triggered
by
a
timeout
of
any
digital
channel.
The
channels
that
are
checked
are
displayed
on
the
following
pages
in
configuration
mode:
1.
GDU

Once
the
FAILED
PATH
message
has
been
triggered,
it
remains
on
the
list
of
messages
until
the
next
power
cycle.
This
latching
was
implemented
so
that
the
message
would
remain
through
the
end
of
the
flight
during
intermittent
failures
(to
alert
the
maintenance
crew).
This
also
keeps
the
crew
from
having
to
repeatedly
acknowledge
messages
in
the
case
of
intermittent
failures.
