Elevator Feel Computer Inputs
The elevator feel computer receives pressure from hydraulic
system A and system B, pitot pressure from the pitot tubes, and
mechanical input from the stabilizer.
The elevator feel computer uses pitot pressure and stabilizer
input to control hydraulic pressure to the dual feel actuator in
the feel and centering unit. The feel force of the feel and
centering unit increases as the airspeed increases.

Elevator Feel Shift Module
During a stall, the elevator feel shift module (EFSM) provides
850 psi system A pressure to the elevator feel computer and the
dual feel actuator. This causes the feel force of the control
column and the feel and centering unit to increase.
See the stall warning system section for more information about
the elevator feel shift module operation. (SECTION 27-32)

Elevator Tab
When the TE flaps are up, the elevator tab balances the
elevator. As the elevator moves, the tab moves in a direction
that is opposite to the elevator direction.

Elevator Tab Control Mechanism
When the TE flaps are not up, the elevator tab control
mechanism changes the function of the elevator tab. This
causes the elevator tab to move in the same direction that the
elevator moves.

General
These are the components of the elevator and tab control
system:
* Control columns (2)
* Elevator forward control quadrants (2)
* EA and EB; left and right body cables
* Elevator aft control quadrants (2)
* Elevator input torque tube
* Elevator power control units (2)
* Elevator output torque tube
* Elevators (2)
* Elevator feel computer
* Elevator feel and centering unit
* Balance panels (6) and tabs (2)
* Elevator tab control mechanism
* Neutral shift rods (2).
Control Columns
The control columns move the elevator forward quadrant and
the elevator control cables.
If a jam occurs in one column, a breakout mechanism allows
elevator input by the other column.
During stabilizer electric trim operation, if the pilot moves the
control column in the opposite direction, the column cutout
switches make the stabilizer electric trim stop.
Elevator Forward Control Quadrants
The elevator forward control quadrants connect to the control
columns and transmit pilot forces through control cables to the
elevator input torque tube.
Elevator Control Cables
The elevator left and right body control cables EA and EB move
the elevator aft control quadrant, which provides an input to the
elevator input torque tube.
Elevator Input Torque Tube
Pilot, autopilot, and flight control computer inputs move the
elevator input torque tube. The elevator input torque tube
moves the elevator PCU input pogos.
Elevator Power Control Units
The two elevator power control units (PCUs) move the elevator
output torque tube. The PCU rod end is fixed and the housing
moves the elevator output torque tube. Input from the input
torque tube is transmitted through input pogos to the PCUs.
Elevator Output Torque Tube
The output torque tube moves the elevators through the
elevator control rods.
