The ‘avionics’ are all radio modules that are located in the pedestal (After Electronic panel).

Avionics refers to the electronic systems on board. The word avionics is a combination of aviation and electronics.

This includes radios and systems for communications, navigation, sensors, indicators, and e.g. weerradars.

Which systems can be found in the avionics pedestal of the B737-800 :

  • COM 1 VHF
  • COM 2 VHF
  • COM 3 VHF (backup)
  • NAV 1
  • NAV 2
  • ADF 1
  • ADF 2
  • Transponder
  • Audio Panel
  • Cargo Fire Panel
  • WX Radar Panels
  • Rudder & Aileron Trim, Cockpit Panel
  • Fire Panel
  • Data Printer
  • Selcal Panel

The different radio modules and setup of the pedestal varies from airline to airline. Each company has its own setup and number.



Nowadays, there are several suppliers of radio modules. The front runners are CPFlight/FlyEngravity, Flight Deck Solutions, Opencockpits, Simworld and Sismo Solutions.

Where you buy depends on the superb, interfacing and the realism that it strives for.

For me, it was pretty easy to make a choice. I already had the MCP/Efis and ICS of CPFlight. So the logical choice was to go with CPFlight/FlyEngravity (CPFlight makes the electronics and FlyEngravity the panels).
The CPFlight-radio modules are tailored to the CPFlight MCP/Efis and of course also on the ICS (Integrated Circuit System).

An important reason is also the realism of the modules. Everything is actually made of nice material and they are all very nicely finished. The backlighting is also wonderful to see.

Each module is well packed in a box and comes with a 5-pin cable and 4 DZUS's with bolts + mini-manual.











The ‘Avionics’, which I my pedestal have equipped is the standard setup of CPFlight. I also have a bit of a ‘lookalike’ running of the Ryanair Boeings (see photos).

  • Aluminum cover plate large (1x);
  • Aluminum cover plate medium (2x);
  • Decals;
  • Handles with (2x);
  • Intercom panel;
  • Additional switches on the ‘cover plates’.


What I have omitted is the Selcal panel, the HF modules and the Data (Acars) printer.
Selcal and HF I'm not going to use. The printouts of Acars information, I also do not use since this info is already to be found in the CDU (Prosim).

Cover plates (cover plates)

These cover plates serve to make the openings in the racks, which are not filled with radio modules, to cover.
The three ‘cover plates’ I use the ‘large’ version to use as ‘mouse pad’. With a small wireless mouse gives this a ‘cover plate’ enough surface for the mouse movements.








In a homecockpit, we are working now, once with computers and so is a mouse with a keyboard is not the way to think. One mouse and one keyboard to be used for the different cockpitcomputers and this via’ Input Director’.

The small and flat keyboard has its place in the checklisthouder in addition to the TQ.

The 2 " medium cover plates’ for the installation of additional potentiometers with buttons and press - and rockers. And also for confirming some decals.
The various additional switches are useful for configuring additional features in FS. Always useful to have at hand.


The decals are again copied from the Ryanair in-boxes (boxes for the Neighbors). This to add a little extra finish.








One decal indicates the registration number of the aircraft and this in ‘club colours’ of the Wildcats – Flight Sim Club 27Sqn (White-blue-black).








The other decal shall specify the Cat III rating.








I also have an extra decal for the Fire Panel. This was not yet provided at the CPFlight Fire Panel.

Handles with

On the two medium, cover plates, there is an stainless steel handvatje placed (Gamma).








They give the ‘lookalike’ of a Ryanair-pedestal and they are also convenient to the 2 outer racks (with modules) from the pedestal to the lifts.








Intercom panel

Since the ASP module of CPFlight is not equipped of an intercom system (Comms between Cpt and F/o) I go this.








Further information regarding this intercom System is to be found on the following page : http://www.flightdeck737.be/hardware/avionics-pedestal/intercom/



The mounting of the various modules and panels in the pedestal happens very easily.








In the pedestal be 3 ‘racks’ (FlyEngravity). This aluminum inbouwracks rest on a metal or wooden frame around the inside of the pedestal. This framework is slightly lower than the outer edges of the pedestal.








These ‘racks’ close to each other and are embedded between the outer edges of the pedestal. By the raised edges of the pedestal, they can not shift or from the pedestal to get to.

The ‘Fire Panel’ is built into the front compartment of the pedestal.



One can make the ‘racks’ if necessary, screw together, but that is not necessary. When they are not stuck together they are also easily separate from the pedestal lifts.

The ‘racks’ are provided with pre-drilled holes. So it is only the radio modules/panels into the holes to screw in with ‘aluminium aircraft fasteners replicas’ (DZUS).

This DZUS's are supplied as standard with each module. They should all be painted in Boeing grey.

The radio modules can then have additional hold with to the rear a nut, but that is not necessary.


The ‘racks’ do not belong to the CPFlight-radio modules and must separately be purchased from FlyEngravity.

Around the pedestal the aluminiumkleur of the ‘racks’ do not let parting with the Boeing-gray of the radio modules I've used the ‘racks’ are also in a grey color.










Connecting the radio modules is again a ‘simple comme bonjour’.

With the delivery of the modules, each module is equipped with a 5-pin cable. On the back of each module there are 2 inputs are provided for a 5-pin cable.

Each module is daisy-chain connected to each other. Any of the 2 inputs is ok.

The Flood/Panel Bright module has 4 inputs for a 5-pin cable.








The far right goes in the direction of the MCP/Efis, or in my case to the ‘main board’ of the ICS system. To this connection there is an additional 5-pin cable, 3 m with the standard package delivered.








On the ICS system (main board) 2 inputs are provided for a 5-pin cable.
One of them was already occupied by the MCP/Efis. The second input is intended for the radio modules (coming of the Flood/Panel bright module).








The 3 remaining 5-pin inputs (Out1, Out2, Out3) will be connected to the first radio module of each montagerack in the pedestal.

One of the last radio modules can then be connected to the Fire Panel.


In double modules such as VHF, NAV and ADF must on the back be chosen which module if 1 or 2 should act. It is necessary a jumper on the back to move (position 1 or 2).
In the ASP-modules, this is not necessary. Which are each linked with a flat cable.



The two Audio Selector Panels (ASP) are connected with a flat cable.








The WX and the Cargo module with a flat cable, connected to each other.








Ditto for the Flood/Panel Bright module and the Stab Trim/Cockpit-panel. The Flood/Panel Bright module has a separate power supply is needed. This ‘DC power supply’ should also be a standard for Flood/Panel Bright module.

Furthermore, the Flood/Panel Bright module on the rear on a ‘terminal block’, which internally is connected with a built-in standard potentiometer 0.5 W, and this for the control of the Flood Light. This potentiometer is completely independent and separate from the whole circuit.
To the FLOOD-light in the FWD Overhead to make it work, and this together with the FLOOD CPFLight module is sufficient for some minor technical adjustments.
More info about this : http://www.flightdeck737.be/pc/flood-light/

The Stab Trim/Cockpit By-panel on the back and a 2-pin terminal block for the connection of a switch. This can be the light on the front " CABIN BY UNLOCKED power on and off.











When the CPFlight-radio modules are connected to the MCP/Efis or ICS is there to continue the configuration no action is required. Everything is done automatically via the MCP/Efis connection.

If the CPFlight-radio modules are connected to a separate USB connection and not via the CPFlight MCP/Efis, it is necessary to be in the Prosim-configuratietab this separate connection box.



To the idea of Henk Timmermans and René Hoep I have a protective cover (sleeve) made to be on the pedestal. This to the pedestal to protect it from dust and falling objects. Good idea of who the guests !

The yellow/black tape (on the board) I have met in a legerstock, the image ‘No Step’ is searched via Google and printed out on glossy photo paper. The handles with the Range.
