automatic function to work, you must first set it to auto and then re-select the aircraft type from the IDENT
page.
Example:
Press the MENU key twice. This will bring up a special user menu of extra settings. These items are not
normally seen on the aircraft by pilots. They would be used in a software maintenance situation and in a
similar way we use them to set specific user options for the CDU software. Press the LSK key next to
DISPLAY. Then select the LSK key next to the option KEY CONFIG. This will then switch to AUTO from
MANUAL or vice versa.
Navigate back to the IDENT page (INIT REF -> INDEX). Now re-select your
aircraft type from the Ident LSK option. The CDU will be refreshed and the
new keyboard layout will be shown. In this example the 747-400 CDU key
layout has been generated. This is more than just a graphical adjustment.
Some keys are different and will offer different navigation functions. If you
are likely to switch between aircraft types often, you may wish to leave the
above display option in AUTO. If you are using hardware with your CDU,
and your hardware is unlikely to change then you should set the function
to MANUAL again once you have the keyboard layout that you require for
your specific layout. This will reduce the chances of a hardware / software
keyboard miss-match in the future operation of the CDU.

Step 3 IRS Position
The CDU needs to know where it is in the world
just like the CDU on the actual aircraft. If you do
not set the CDU position then parts of the Glass
Cockpit Displays will be blanked out from view
with Amber warning flags ATT and MAP. This is a
safety feature of the GC if a position uncertainty
occurs whilst the aircraft is on the ground.
To set the CDU position, press the LSK key that is
next to the INDEX option (bottom right). Then select the LSK opposite the POS option. Now the position
page will appear.
You can either enter a specific airport code in the REF AIRPORT or you can press the LSK next to the REF
AIRPORT line and the CDU will detect the current airport from MSFS. The LAT and LONG will appear
opposite. Select the LSK to bring the new LAT and LONG into the Scratch Pad. Then press the LSK next to
SET IRS POS and the new LAT and LONG will be taken into the IRS position and set. Now the CDU will
have a fix and the Glass Cockpit display warning flag indicators ATT and MAP will disappear.

Step 4 Additional Settings CDU
The CDU has additional settings that can be selected from the settings page. The following are required to
be set for your own preference. This only needs to be done once unless you decide to change these
options at a later date.
• Auto Tune NAVS, this will tune the NAV radios automatically, this can be a ON / OFF selection
• FAF, the range of the Final Approach Fix can be entered here
• MIN AGL LNAV, the minimum altitude for LNAV engagement
• TIME, select either system or MSFS Zulu time
• MESSAGES, this will turn on or off messages that the FMC produces in the Scratch Pad
• QNH, select your preference
• FUEL, select your preference
• PREFLIGHT, if set to on will require a full Pre-Flight Set-up of the CDU
• FLUSH, will flush all data from the CDU after the aircraft has landed or upon each re-start of the
CDU.
The CDU is now in a basic configuration for use.
Other user settings that can be select are self explanatory:
• NAV/COM/XPDR, you can enter radio frequencies
• EFIS selectors can alter GC displays via the CDU
• SPD PROTECT, artificial simulated flap and speed protection
• EXTRAS, simulator rate and freeze modes
If you require to reset or gather information about your current NETDIR status, this can be done by going
to the INDEX page of the CDU, and selecting MAINT. Then select the NETDIR option.

Step 5 Flare Altitude CDU
If running the CDU the flare altitude must be set. If you do not change a/c types then this only needs to be
set once. The flare altitude will determine at what point on an Auto Land the aircraft will start the Flare.
The flare altitude will probably be set at 30 by default; you may want to change this value depending on
what a/c type you are using.
From the INDEX page select MAINT. From this page select the LSK for A/T. In the A/T page if you want to
assign a new flare value, enter it into the scratch pad, and then enter this value by pressing the LSK next to
the FLARE AGL setting. The new value will be added.
