Alerting
Message Alerting
Message alerting functions include visual and aural alerts, and digital
outputs to various Line-Replaceable Units (LRU). The outputs are
intended to drive visual or aural alerting when a new uplink message is
received. The digital outputs provide messaging alerts that may be
used by other devices for additional alerting functions, such as the
FMS MSG annunciator.
Alert Inhibiting
UniLink Alert Inhibiting operates in order to suspend the output of
message alerting during critical phases of flight (i.e., takeoff and
landing). Displayed UniLink advisories are not suppressed during
critical flight phases.
NOTE: If UniLink transitions out of the takeoff phase due to
transitioning directly into the landing phase, UniLink will
continuously inhibit alert outputs. This ensures there are no
aural alerts that could potentially distract the crew.
