15.7 Tile 4 – Crew Alerting System (CAS)
The Crew Alerting System (CAS) provides the pilot with information related to
abnormal aircraft conditions and aircraft system status. Messages are normally
displayed on Tile 4 on the MFD; however, in the event of an MFD failure CAS
messages are displayed on the PFD in composite mode. Visual alerts are provided
on the master warning and master caution light button on the autopilot control panel.
Aural alerts are also provided. CAS messages are categorized according to the
severity of the condition, and are displayed in the message window with the most
recent messages (within a categorization) presented at the top of the list. The aural
components of CAS are voice messages and alert tones that are transmitted to the
crew headphones and speakers. A single concentric knob located on the upper right
side of the MFD is used to select and acknowledge CAS messages.
15.7.1 CAS Message Classifications & Hierarchy
CLASSIFICATION
There are four classifications of CAS messages: warning, caution, advisory, and
status.
Warning Messages. A red warning message alerts conditions that require
immediate flight crew awareness and response. Examples include aircraft or
systems in a hazardous configuration and serious system failures.
Caution Messages. An amber caution message alerts conditions that require
immediate flight crew awareness and subsequent flight crew response.
Examples include malfunctions or failures which could result in a hazardous
airplane condition.
Advisory Messages. A white advisory message alerts conditions that require
flight crew awareness and may require subsequent flight crew response.
Examples include a system malfunction or failure leading to a loss of redundancy
or degradation of a system.
