AIR CONDITIONING AND PRESSURIZATION
NOTE
This sequence is not active during manual pressurization operation.
When the airplane is in the climb, the CABIN ALT warning and CABIN ALT caution decrease proportionally to the airplane altitude. As soon as cabin altitude reaches 7,330 feet or airplane reaches 41,000 feet or above the CABIN ALT caution is reset to 8,200 feet and the CABIN ALT warning is reset to 9,000 feet.
If the Landing Elevation is switched to less than 7,230 feet before cabin altitude reaches 7,330 feet, CABIN ALT caution / CABIN ALT warning message may be displayed as the CPC is reverted to the normal message threshold of 8,200 feet and 9,000 feet respectively.

Volume 2 Flight Crew Operating Manual Rev 12, Aug 14, 2006
NOTE
This sequence is not active during manual pressurization operation.
The take-off is identical to normal take-off above 7,230 feet. When the airplane starts to descend, an aborted take-off sequence is initiated. The landing is similar to landing above 7,230 feet.
Rate Limit Selection
Cabin rate of change control is automatically controlled during ground and flight sequences. The airplane is normally flown with the rate limit selector set to NORM position. The automatic rate of change control is based upon +500 ft/min and .300 ft/min. The airplane cabin altitude rate will vary within these normal limits, to follow the pressurization schedule. The cabin rate is displayed on the STAT page. If the cabin is in a climb, the arrow will indicate ↑. If the cabin is in descent, the arrow will indicate ↓.
NORM: 500 ft/min up, 300 ft/min down.
FGF0210_020
It is possible to manually override the automatic rate of change control limits, through the rate limit selection on the PRESSURIZATION control panel. In the HIGH position, the rate limits are up to +800 ft/min and .800 ft/min. The cabin rate will vary between these two limits as required to maintain the pressurization schedule.
HIGH: 800 ft/min up, 800 ft/min down.
FGF0210_014
With Landing Elevation set to 5,674 feet or higher, the cabin rate of change is automatically controlled by the CPC independent of CPC RATE selection when the airplane is descending with cabin altitude higher than 5,674 feet.
Rev 12, Aug 14, 2006 Flight Crew Operating Manual Volume 2 CSP 700.5000.6 02.10.55
AIR CONDITIONING AND PRESSURIZATION
The rate of climb is automatically limited to:
.
540 fpm if airplane vertical speed is ≤ .1150 fpm.
.
2457 fpm if airplane vertical speed is ≥ .3450 fpm.
.
Between the above values the cabin rate of change is proportional to airplaine vertical speed.
