The CRJ series of airplanes actually have a very understandable message system called Engine Indicating Crew Alerting System or EICAS. The panels are located in the middle of the display consoles.
There are four types of messages: Warning, Caution, Advisory, and Status that can be displayed to the pilot. Each type of message has a different importance to it and are represented in different colors.
Warning and Caution Messages are displayed on ED1.
Warning Messages
- Warning messages are in red text and are conditions requiring IMMEDIATE action
- They are always accompanied by a triple chime, flashing the MASTER WARNING lights, and possibly an aural/voice message
- Check the QRH to resolve the condition or call maintenance if you are not sure
- Posted in chronological order on top of ED1
- Warning messages can only be removed by correcting the condition that caused the message.
- If there are more than 24 messages, only the most recent 24 messages will displayed.
- Warning messages cannot be paged through or boxed.
Caution Messages
- Caution messages are yellow text and are conditions requiring CORRECTIVE action
- ALWAYS accompanied by a single chime and flashing MASTER CAUTION lights
- Check the QRH to resolve the condition or call maintenance if you are not sure
- Listed in chronological order, but ALWAYS below WARNING messages
- Can be boxed/removed on the ground with both engines stabilized at IDLE and < 1 page of messages
- Can be boxed/removed in flight with 1 engine running
- Boxed message indication on EICAS – MSGS
- Page through multiple pages using EICAS Control Panel (ECP) CAS button
- If new CAUTION occurs while boxed – the new CAUTION message appears ABOVE boxed MSGS
Advisory and Status Messages are displayed on ED2.
Advisory Messages
-
Advisory Messages are green text and show that a safe condition exists like “Fuel Pumps On”
-
System response or acknowledgement messages
-
Removed by de-selecting a switch or system like when turning the Fuel Pumps off
Status Messages
-
Status Messages are white text and indicate abnormal conditions or low priority failures
-
Check the QRH to resolve condition or call maintenance if you are not sure
-
Can be removed/boxed/paged
-
ECP STAT button will page through status messages if more than 1 page
-
Upon reaching the last page, STAT will then box messages
-
New STATUS message will un-box all status messages
I will talk about when Warning and Caution Messages are inhibited in my next entry.
Till next time…
