ProSim737 CDU

Main Page > ProSim737 Manual > ProSim737 CDU

ProSim737 CDU is the module that simulates the Control Display Unit. Both pilots have a CDU at their displosal, and the units are situated on the right (Captains' CDU) and left (First Officers' CDU) hand side of the lower EICAS display.

The CDU allows pilots to mainly interact with the Flight Management Computer (FMC) and with the Datalink communication systems (ACARS & CPDLC).

The ProSim737 CDU module does not contain actual FMS logic. It is merely a module to access the Flight Management System (FMS) contained in the ProSim737 Systems module. Like all other modules of the ProSim737 suite, it is possible to run ProSimCDU from any computer connected to the same network as ProSim737 Systems.

For every hardware CDU connected, a separate folder containing all files from ProSim737 CDU must be created, if both the captain and first officer's CDU's are connected to the same computer.

ProSim737 v3 CDU Main Menu

This is the basic main menu of the ProSim737 V3 CDU. With LSK1L, the FMC may be accessed. By pressing LSK6R, the MAINT menu is accessed.

1 Software

1.1 Installation

The ProSim738 CDU module can have multiple instances on the same computer, but must be in separate folders. Simply copy and rename the first folder to, for example 'ProSim738 CDU - CAPT' and the second one to 'ProSim738 CDU - FO'. Each folder will have its own configuration file.

1.2 Configuration

The are a host of configuration options available in order to personally adjust the software. The configuration of ProSim737 - CDU has been divided into three tabs:

1.2.1 Options

On this tab, general options of the CDU module can be modified to your requirements.

ProSim737 server: If running ProSim737 CDU on a different computer than ProSim737 Systems, the IP address of the computer running ProSim737 Systems must be filled in. For more information, please refer to the Initial Setup page of this wiki.

Fonts: If required, it is possible to change the size and font used by the ProSim737 CDU module. A very realistic font comes included with the ProSim737 CDU module. Sometimes hardware manufacturers advise a change to the font size. Please consult your hardware's manual for correct sizes.

When using a hardware CDU, the following options are advised to

turn on:

• Start full screen
• Stay on top
• Hide mouse cursor
• Allow remote computer shutdown
• Use color.

Turn off:

• Show frame
• Show border

Set 'CDU Role' to the required setting: Standalone, Captain or First Officer.

1.2.3 Screen Layout

ProSim737 v3 CDU Configuration - Screen layout tab

Instructions can be found on this tab on how to adjust the screen layout in order to adjust the software display the desired hardware display. The lines can be lined up on the display with the hardware unit Line Select Keys. Use the 'Reset Layout' button to return to 'factory settings'. See the 'Adjusting for hardware CDU' paragraph below for more information.

1.2.4 Adjusting for hardware CDU

For CDU hardware unites connecting the display through VGA or DisplayPort, it might be required to manually adjust the size of the CDU software display. First, right-click on the CDU display, and then click 'Line Setup Mode'. A yellow box is shown, indicating the line currently selected to be modified. By clicking on the left line select keys, a different line can be selected to adjust. LSK1R is used to select the menu line (line displaying the pages' name at the top) while LSK6R is used to select the scratchpad at the very bottom of the display.

To modify the lines to suit the desired hardware display, use the following keys on your keyboard:

U / D	Up / Down
L / R	Left / Right
W / S	Widen / Shorten

1.2.5 ProSimUtils

ProSimUtils (PSU) is a utility developed by Humberto Miguel, who is a developer for ProSim-AR's. It is a free add-on, which simulates two datalink systems: ACARS & CPDLC For more information and support on PSU, please visit the dedicated subforum on the ProSim-AR Forums.

1.3 Maintenance Menu

The Maintenance menu is a submenu accessible through the CDU, which in real-life is used by avionic engineers to access several systems of the 737. In ProSim737, this menu is used to access several functionalities related to simulation.

1.3.1 Pauze & Freeze

The Pauze (LSK1L) will pauze the complete simulator, and acts as a alternative to pressing the 'P'-key on your keyboard. Click the line select key again to un-pause the simulator. The Freeze (LSK2L) will pause the simulator, but will allow adjustments to roll and pitch without changing position.

1.3.2 Sim Rate

By pressing LSK3L the simulation rate can be adjusted. Options are 'normal', '2x' and '4x'. This will decrease the real world time required to perform a flight, but might cause a blurred effect and other negative effects.

1.3.3 COM/NAV

LSK4L will open the COM/NAV page, which gives an overview of all communication and navigation radio's and the frequencies currently dialed in. This also includes the transponder. It is possible to change frequencies by using the numbers on the numeric keypad of the CDU.

1.3.4 Reset FMS

This will reset the FMS (FMC) to a clean state. Note that this will undo any changes made to the FMS, such as performance data, route, etc. Press LSK5L once to activate.

1.3.5 Ground service

The Ground Service menu allows the performance of several tasks concerning ground operations:

LSK1R will turn on or turn off the ground power. When ProSim737 has been configured to start in cold and dark state, ground power will be connected by default. This option can be changed in the ProSim737 Instructor Operating Station.

LSK2R gives you the option to turn the ground air conditioning on or off. By default, this option is set to off.

LSK3R will start the pushback. The direction (Straight, Left, Right) of the pushback may be changed by pressing LSK4R until the desired direction has been selected in green.

LSK5R will open the refueling menu. Use the numeric keypad of the CDU to enter the desired amount of fuel in KG or LB (depending on the configuration in the Instructor Operating Station) and then transfer it to the desired tank by pressing the correct LSK. Finally, press LSK2R 'REQUEST' to start the refueling.
