Control
The system A flight control switch (FLT CONTROL A) on the
flight control panel controls the system A flight control shutoff
valve. The system B flight control switch (FLT CONTROL B)
controls the system B flight control shutoff valve.
Operation
A 28v dc motor controls each flight control shutoff valve. The
valves are normally open which allow pressure from each
system to the flight controls. When you move the flight control
switch to the OFF position, the valve closes.
Monitor
When the valve is open, the indicator lever is in position 1.
When the valve closes, the indicator lever moves to position 2.

Purpose
The low pressure warning switch gives an amber light
indication when there is low system A or B pressure to the
flight control system.
Location
The low pressure switches are a part of each flight controls
hydraulic modular package.
The amber indicator lights are on the flight control panel on the
P5 forward overhead panel.
Power
The master dim and test (MD&T) system supplies power to the
lights.
Control
The low pressure light connects to the low pressure warning
switch only when the flight control switch is in the ON or OFF
positions. When the flight control switch is in the STDBY RUD
position, the standby rudder shutoff valve controls the low
pressure light through the valve position relay. See the standby
hydraulic system section for more information about the
standby rudder shutoff valve. (SECTION 29-22)
Operation
The low pressure switch is open when hydraulic pressure is
available to the flight controls. The switch closes when the
pressure is less than 1300 psi and opens when the pressure is
above 1600 psi. This supplies a ground to the low pressure light
when closed.
When the flight control switch is in the STDBY RUD position, the
low pressure warning switch is not connected to the low
pressure light. When the standby rudder shutoff valve is in the
closed position, the valve position relay provides a ground to
the low pressure light. When the standby rudder shutoff valve
moves to the open position, the valve position relay energizes
and removes the ground to the low pressure light.
Monitor
When the low pressure light comes on, the master caution and
the FLT CONT annunciator also come on.

General
This is the system A and B hydraulic distribution to the primary
flight controls. The pressure goes to the flight control hydraulic
modular package. Then it goes through the flight controls
shutoff valve. A low pressure warning switch monitors for low
pressure to the flight controls. Then the pressure goes to the
using components.
