SYSTEM MESSAGE ADVISORIES
NOTE: This Section provides information regarding message advisories that may be displayed by the
system. Knowledge of the aircraft, systems, flight conditions, and other existing operational priorities must
be considered when responding to a message. Always use sound pilot judgment. The Phenom 100 Airplane
Flight Manual (AFM) takes precedence over any conflicting guidance found in this section.
This section describes various system message advisories. Certain messages are issued due to an LRU or an
LRU function failure. Such messages are normally accompanied by a corresponding red “X” annunciation as
shown previously in the Prodigy
®
System Annunciation section.
