### AIRPLANE GRAPHIC <a href="#airplane-graphic" id="airplane-graphic"></a>

* Static display that shows the location of flight control surfaces and status of the flight control actuators.

### SURFACE POSITION STATUS <a href="#surface-position-status" id="surface-position-status"></a>

* Displays the surface position and status.

### FLIGHT CONTROL SYSTEM STATUS ANNUNCIATIONS <a href="#flight-control-system-status-annunciations" id="flight-control-system-status-annunciations"></a>

* Status annunciations are shown in a table format for three surfaces.

### ACTUATOR STATUS ANNUNCIATION <a href="#actuator-status-annunciation" id="actuator-status-annunciation"></a>

* The rudder has two actuators, upper and lower. Each left and right elevator surfaces have two actuators, inboard and outboard.

### AXES MODE ANNUNCIATION <a href="#axes-mode-annunciation" id="axes-mode-annunciation"></a>

* Axes mode annunciations are shown for the rudder, left and right elevator.

### HYDRAULIC SYSTEM SOURCE ANNUNCIATION <a href="#hydraulic-system-source-annunciation" id="hydraulic-system-source-annunciation"></a>

* Hydraulic system source annunciations are shown for the rudder, left and right elevator.

### PBIT REMAINING TIME READOUT <a href="#pbit-remaining-time-readout" id="pbit-remaining-time-readout"></a>

* Digital remaining time readout displays the hours until the electrical and hydraulic PBIT expire.
* Electrical PBIT is automatically performed during power up after the airplane is powered by any AC source and takes approximately 3 minutes to complete.
  * Will be interrupted if any electric hydraulic pump is turned ON, if the Flight Control Mode Buttons are cycled or if AC power is interrupted while the test is running.
* Hydraulic PBIT is performed automatically only on the ground when all 3 hydraulic systems are pressurized and takes approximately 1 minute to complete.
  * Will be interrupted if any flight control surface is moved.
  * PBIT is not performed if the temperature within the hydraulic reservoir is lower than 10 degrees Celsius.
