    EFIS (Electronic Flight Information System)

    The EFIS is the Electronic Flight Information System which actually consists of several units, mostly digital displays as the PFD, the NG (NGD) and the EICAS but in order to control these, there is also a control module and this module is the one that I have tested. To see the usage of this module within FSX I have tested it using the default B737 and the PMDG B737NGX.

    The EFIS is a replica of the real EFIS found in the Boeing B737 aircraft with a few exceptions - the version that I have tested is the EL-series which is a light version of the original EFIS in regards of usage/appearance, but in regards of functions they are identical.

    CPflight has created both the EL version and the PRO version which is a 100% replica of the real EFIS, but my test is only done on the EL version. The main difference is the rotating switches where the left and right rotator in the PRO/real version is dual rotators and in the EL version they are single rotators with a push button. Also the two center rotator switches are different but that is only the knob. Here below are two images of the EFIS for the B737 where the left version is the PRO version and the right one is the EL version.


    The functions which are used with the dual rotator switches are also possible using the EL version. Here you just need to push and hold the push button within the rotator switch at the same time you turn the rotator to either the left of right. This function will apply the same changes as if you were using the secondary rotator (outer ring).

    The EFIS consists of several rotator switches, several pushbuttons and two toggle switches which all controls input and views on the PFD, NG(D) and the EICAS displays.

    Top Left Rotator is the MINS function that adjusts the minimum altitude. This is controlled by rotating the rotator to either the left or right. This rotator can also select if it should according to either Radio or Barometric altitude.

    Top Right Rotator is the BARO controller that controls which "format" the display will be in as e.g. IN or HPA. This is the barometric measurement / air pressure measured in either inches/millimeters mercury or Hecto Pascal which is used for e.g. the altitude indicator. The rotator is also used to adjust the barometric altitude setting.

    Bottom Left rotator is the Mode Selector that is directly connected to the NG(D) display and here the pilot can change the display to show various views as e.g. VOR and MAP etc.

    Bottom Right rotator is the Range Selector which is used together with the Mode Selector rotator. The Range Selector is also directly connected to the NG(D) display and adjusts the range displayed in the NG(D).

    The two toggle switches control the view of the relative information of the selected station as either VOR1/2 or ADF1/2. Both toggle switches are ON/OFF/ON switches meaning that the center position is an OFF position.

    In between the two top rotator switches there are located two pushbuttons - the FPV and the MTRS. They are both directly connected to the PDF and the FPV shows the Flight Path Vector while the MTRS enables the pilot to get the PFD altitude readout also in meters and not just feet. This is indicated by adding a small colored box with the meters indication on top of the feet indication in the right column of the PFD.

    The last part of the EFIS control unit is the line of buttons at the bottom of the panel. In total there are here 7 buttons that again are connected directly to the NG(D). They control functions as various views of stations, airports, waypoints etc. within the selected range in the NG(D) display and more - to get the full overview please view the EFIS Wiki.


    Connecting and installing this module was easy - again if the MCP is already installed including drivers etc. then there is no need for additional drivers. It truly is just a simple plug and play module that when connected instantly worked perfectly.

    The connection is the DC chain that is connected directly to the MCP and since I have other console modules also connected in the DC chain - these were connected to the second DC plug on the back side of the EFIS.

    The back side of the EFIS consists of two DC plugs - they both work the same way, so it doesn't matter which plug you connect the EFIS to the MCP with and vice versa with the DC string to the console modules. If I only connected one EFIS to the MCP without the console modules I would not need any additional power supply, but if I were to add both the CPT and the F/O EFIS to the MCP, this would only work if I added a power supply to the MCP.

    In my setup I have not connected a power supply to the MCP even though I have connected the string of console modules to the EFIS and MCP, but this works perfectly because I have connected the power supply to the BRT modules instead - they are then able to supply my complete DC chain with sufficient power.

    Furthermore the EFIS's back side also has a small jumper that as default is set to CPT. This means that the EFIS is now working as the captains EFIS and not the F/O's EFIS. To change this is very simple - just take out the jumper and place it as the F/O instead (move it one step to the right). However the jumper is not a switch which is why you need to pull it out, move to the right and put it back in.

      Nice review.
      I miss the information about the TCAS test function of the transponder, does it work or doesn't it?
      About the stab trim and flood panels: they are exactly like the real thing, the airline orders their own version so you always get different versions in different airlines.

      Hi, yes I did a follow-up on the stab trim and found that they are actually very realistic. It seems that there just are several versions and what CPFlights did, was the newest version and what I found during the test was an older version. This however does not change my rating since the BRT modules are mostly eye candy.

      The TCAS - I am not sure what you mean, but I can say that all rotator switches, toggle switches and the push button all activates the corresponding button/switch in the virtual ATC when using PMDG737NGX. But some really nice modules for sure which bring a lot to the flightsim experience in my opinion.
