CABIN PRESS Control Panel
1. Outflow VALVE Indicator
Displays position of outflow valve during manual and automatic operation of
cabin pressure control system.
2. CABIN PRESS Manual Rate Selector
This selector is a momentary action, two speed rotary switch that adjusts the
position of the outflow valve when the system is in manual. The first detent
causes the valve to move slowly. The second detent causes the valve to move
faster towards DESC or CLIMB (open or closed). This allows for rapid
recovery from failure conditions as well as a fine tuning of cabin altitude rate
change.
3. CABIN PRESS SYSTEM SELECT Switch - amber
This is an alternate action switch that allows selection between manual and
auto modes.
There are 2 alternating auto channels. During auto operation, one of the auto
channels is not used. Each time auto is selected, the previous unused auto
channel is activated.
SELECT - Illuminates amber if the system is in manual with the switch in
auto.
