FUNCTION

- Alerts crew of operational problem or system malfunction on Central Warning Panel - CWP

CWP also known as:

- EICAS - Engine Indicating & Crew Alerting System - Boeing

Or,

- ECAM - Electronic Centralised Aircraft Monitoring - Airbus

- Replaces the Flight Engineer

DEGREES OF WARNINGS Colours (with the G1000, you should be all over this by now!)

- Warnings - Master warning

- Cautions - Master Caution

- Advisories

- Operating normally

- Status messages

OPERATING PRINCIPLE - Older School Shown

Centralised display, Insty Panel Eyebrow

- "MASTER WARNING" lights

- "MASTER CAUTION" lights

- Specific system malfunction lights grouped on a Central Warning Panel (CWP) screen. (Older - separate panel with ladder lights)

- Aural alert, flashing lights, or inverse cursor is stopped when reset button pressed

- Warning on CWP & "MASTER" light remains until corrected

- Redundancy achieved by multiple units: Two or more systems of Vehicle Monitoring Modules or Modular Avionics Units, and/or the use of DC and AC systems

ECAM and EICAS Systems Page and CAS Panel

Displays most A/C systems status

Inhibiting is sometimes necessary to remove unwanted alerts, particularly on the ground

ECAM and EICAS ALERTS

Visual Alerts - lights as previously discussed

Aural Alerts:

- WARNINGS - Bell, voice, siren & wailer sound until corrected or inhibited

- CAUTIONS - voice, beeper & clacker sound until corrected or inhibited

Tactile Alerts - Stall warning, "stick shaker" with "stick pusher" (190.351)

INHIBITING

- To prevent distraction

- Some functions auto-inhibited during engine start

- Some functions auto-inhibited at take-off through a time or height envelope

- Master Caution/Warning reset switch will cancel the master light and resets it for future warnings

- Except for Autopilot disconnect, Takeoff and landing Config, and Overspeed

- Remember the CWP panel alert will stay there

The Central Warning System is intrinsically linked to the communications management system and will feed aural warnings to the crew
