In combination with the MCP (Mode Control Panel) and features such as VNAV and LNAV can you have in a CDU/FMC (Flight Management Computer), a flight (for)programming. This flight, you can then automatically fly from the beginning until the ‘threshold’ of the runway.

The database with navaids, airways, intersections, SIDS and STARS will be monthly up-to-date via the Navigraph-site so you always have the right route, SID and STAR flies.

The FlyEngravity CDU Version 2 comes with a 24V power adapter, 1 Ethernet cable, 3m and 6 painted Dzus replicas.


For the installation of the CDU in the CDU-bay has FlyEngravity a CDC bracket with which the CDU (s) can be mounted. This " CDC bracket I got with the purchase of the CDU. The assembly of the CDU in the bracket happened with the 6 Dzus replicas.


After the installation of the aluminum CDU ‘bracket’ + CDU in the CDU bay, one can start with the connections and the configuration of the CDU.

The CDU is connected to the front with the 24V-power cord comes in and the ethernet cable. The lower portion of the CDU is designed so that there is sufficient space for the connection of the different plugs. One might also notice that there is no VGA connection more is required ...



After the connection of the power cord into an electrical outlet light the FAIL light is just on and there begins a startup sequence of +- 15 seconds. During this startupsequentie the display is black. Afterwards, light the FAIL light again. The CDU is now ready for configuration.


Separate IP address to assign
The CDU is equipped with a processor and can be considered as a separate computer with its own IP address.

It is recommended to all pc's to equip with fixed IP addresses (LAN) and therefore also a free IP address to choose for the CDU.

Check all IP addresses in all the LAN computers and choose a new IP address for the CDU.



By pressing the EXEC key, you get a IPv4 control panel on the CDU display. This is the new IP-address.


After entering the IP address press again on the EXEC key where the IP address is stored in the memory of the CDU (e.g.


Then one can the ethernet cable be connected to a computer, switch, or router.

Configuration Prosim737
Start Prosim737 with the Prosim CDU.

In the Prosim CDU, click on the right mouse button where a screen pops up where you for the drivers, tab select.

In the section ‘Engravity V2 CDU’s’ you enter the IP address of the CDU, then press OK.

Restart the CDU and you're ‘Ready to Fly’.



The FlyEngravity CDU Version 2 it is a beautiful and realistic 737 replica. In comparison with Version 1, the CDU V2 made completely out of aluminum, to obtain a solid.


The black-and-white display (earlier white-gray) of V1 is now replaced by a high-contrast color screen. What black and white should be in the display is now really BLACK and WHITE. In doing so, the color display deep, rich colors. Beautiful!!!

With Version 2 is really getting used : Larger letters/numbers and the correct font, with figures such as one that can be found in a real 737. Wow !















I also having regard to any delays or delays but there is nothing to notice (latency or <0.1 Ms).

The keyboard is now equipped with ‘have tacticle switches " which you now clearly hear a click when pressing the button. The keyboard is also optional according to the wishes of the user (custom made).
As with V1, this CDU also equipped with a backlightverlichting. This backlightverlichting is now much more intense compared to V1. Also, is this light dimmable with a rotary encoder.


The connections and configuration are easy and anyone can be performed. Only one must be a little on the height of LAN settings and IP addresses. For a typical cockpitbouwer, no problem ...


The purchase price of this CDU V2 is the other side of the coin. Taking into account the official price is this expensive toy and it remains CDU for many B737-builders only a wet dream.


If the sell of my CDU V1, the necessary and the like (e.g. during the FSWeekend) and other extras, I'm still ‘cheap’ from ... 🙂


This member of FlyEngravity is a beautiful product and a superverbetering t.o.v. version 1. It makes a world of difference and is compared with the switch from a VW to a Ferrari...!!!





For the right-wing CDU (F/O side) I use a dummie.

Only the top with the buttons and plexiglass for the window. An aluminum plate on the back keeps everything together.

This CDU-dummy is on the right in the CDU bay is placed partially on the Lower Eicas’. The altitude level corresponds to that of the left-wing CDU (Capt).







This dummy is also FlyEngravity.
