Cabin altitude rounded to the nearest 50 feet is presented. If the cabin altitude
exceeds 8,750 ft, a CABIN ALTITUDE caution message appears and the numeric
digits turn amber. If the cabin altitude exceeds 10,000 ft, a CABIN ALTITUDE
warning message appears and the numeric digits turn red. At a cabin altitude of
12,750 ft an aural warning sounds every 15 seconds. To silence the aural warning,
one of the following conditions must be met:
A rate of descent of 1,800 feet per minute or greater.
A descent below 12,500 ft cabin altitude
NOTE:
A CABIN ALTITUDE warning message may indicate cabin depressurization.
RATE (FPM)
Cabin altitude rate of change rounded to the nearest 100 FPM (Feet Per Minute) is
presented. Should the cabin altitude rate be too high, the numeric digits turn amber.
The crew can select the cabin rate of climb or descent between 0 and 2,500 feet per
minute.
DP (PSI)
Differential pressure between cabin altitude and airplane altitude, rounded to the
