The system monitors the carbon
monoxide content in the air in the
cockpit and generates an alert
under the following conditions –
•
If the carbon monoxide
concentration reaches 50 parts per
million (PPM) or more, an alert is
generated within 3.5 minutes
• The alert delay is reduced at
higher concentrations of carbon monoxide. At 400 PPM, the alert is nearly
instantaneous.
•
The alert is displayed on the pilot’s instrument panel MFD. An audio warning is also
generated that is supplied to the pilot’s headset.
The alert will stay ‘ON’ on the pilot’s instrument panel MFD until the level of CO
concentration drops below 50 PPM.
In addition to the warning being displayed on the MFD, the large, green lamp on the face
of the FMS 650 will turn yellow within three and half minutes if the CO level is detected
to be in the region of 50 to 100 PPM. If the level crosses 101 PPM, the lamp will turn red
without any delay.
7.0 Cabin Altitude monitoring and warning
FMS65X and 85X has an in-built pressure sensor that monitors the cabin altitude of the
cockpit. As the cabin altitude increases, the system becomes more sensitive to the
presence of CO in the cockpit. Besides this, the system warns the pilot if the cabin
altitude exceeds preset values. The indications are as given below –
