Aborted Take-Off Above 7,230 feet
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 ↓.

It is possible to manually override the automatic rate of change control limits, through the rate limit

+800 ft/min and −800 ft/min. The cabin rate will vary between these two limits as required to
maintain the pressurization schedule.

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.
The rate of descent is automatically limited to:
• 300 fpm if airplane vertical speed is ≤ +1428 fpm.
• 1260 fpm if airplane vertical speed is ≥ +6000 fpm.
• Between the above values the cabin rate of change is proportional to airplane vertical
speed.

During High Elevation Airfield operation, with CABIN ALT LEVEL HI advisory message
displayed, the cabin rate of change is automatically controlled by the CPC independent of CPC
RATE selection.
The rate of climb is automatically limited to:
• 540 fpm if airplane vertical speed is ≤ −2570 fpm.
• 1260 fpm if airplane vertical speed is ≥ −6000 fpm.
• Between the above values the cabin rate of change is proportional to airplaine vertical
speed.
The rate of descent is automatically limited to:
• 300 fpm if airplane vertical speed is ≤ +1428 fpm.
• 1260 fpm if airplane vertical speed is ≥ +6000 fpm.
• Between the above values the cabin rate of change is proportional to airplane vertical
speed.
Landing Elevation
Landing elevation information is transmitted by the FMS or from the manual selection on the
Pressurization Control Panel. The value used for pressurization control by the CPCs is displayed
on the STAT page.
