INDICATION AND MESSAGING
(Continued)
NOTE
When the amber A-ICE FLUID LO annunciator comes ON
cross-check the anti-ice fluid quantity indication (A-ICE
GAL) to verify a low fluid level condition exists. This system
is designed to trigger the annunciator when anti-ice fluid
quantity reaches two (2) U.S. gallons.
The red A-ICE PRESS LOW annunciator is tied to the two low pressure
sensors in the tail of the airplane. A low pressure condition on either
sensor will trigger the red A-ICE PRESS LOW annunciator, indicating
that system pressure is too low for normal system operation and may
be indicative of potential substandard ice protection performance.
In BACKUP mode, the red A-ICE PRESS LOW annunciator is armed
immediately upon selecting BACKUP ON. If a low pressure condition
exists, the red A-ICE PRESS LOW annunciator will display immediately
on both PFDs warning the crew to exit icing conditions immediately.
NOTE
With BACKUP selected ON, the red A-ICE PRESS LOW
annunciator will momentarily appear and remain ON until
system pressure is sufficient to inhibit the annunciator.
The red A-ICE PRESS LOW annunciator is inhibited for a period of
time in both PRIMARY modes of NORM and HIGH. When HIGH is
selected, any red A-ICE PRESS LOW annunciator will be inhibited for
15 seconds. After the 15 second period, any low pressure condition will
trigger the red A-ICE PRESS LOW annunciator. Selecting PRIMARY
OFF will reset the CAS inhibiting functions.
