V.0.9.1 Key Features

Welcome to the Working Title CJ4 v0.9.1. This is a hotfix release for 0.9.0 to fix the most pressing issues that came up after release.


  • Fixed issue where ATC window did not refresh electrical system status properly
  • Fixed issue where map lines would be improperly drawn in certain situations and zoom factors
  • Fixed issue where after flying one hold, LNAV would not fly any additional holds
  • Fixed issue where LNAV would skip to the last hold if holds were on back-to-back legs

V.0.9.0 Key Features

Welcome to the Working Title CJ4 v0.9.0. We have a number of features we're excited to deliver, including an amazing flight model overhaul by Metzgergva, who has a large number of professional flight models under his belt, including Aerosoft's upcoming CRJ. We think it's a joy to handfly now, and we can't wait for your feedback. We've also added the ability to program holds into the FMC, which is a major feature to anyone who likes to fly online, and brings us just that much closer to the real plane. Other fantastic features include flight director lateral guidance and crosshairs option, TOGA mode, user waypoints, dual comm support, map enhancements, and a number of other things.


Installation is easy, simply copy the workingtitle-aircraft-cj4 folder inside the zip file to your MSFS Community folder.

Important: We recommend that you fully delete the previous workingtitle-aircraft-cj4 folder before copying this release.

Default Livery Conflicts

The alternate default liveries that now ship with MSFS are not compatible with the CJ4 yet at this time. They currently ship with panel.cfg files that do not include our FADEC module. Please use the standard livery or a known compatible 3rd party or community livery.

Remarks to flight plan synchronization between the Game and FMS

The FP SYNC option is one way: it updates the simulator flight plan from the FMC. To load a plan into the FMS you can either enter it manually or use the FPLN RECALL (GAME/SB) option in IDX -> PAGE2 -> ROUTE MENU

Due to the increased accuracy and capabilities of the FMC managed flight plan, you may find that the sync to the game does not always work as expected or does not reflect the FMC flight plan exactly.

V.0.9.1 Fixed

6/Post a Comment/Comments

  1. When I click on the download now it takes me to another page and wants me to download a setup.exe file. I just want to get the cj4 mod.

  2. cierra esa pagina, es publicidad.
    sigue dándole a descargar y bajaras un archivo rar de 74mb

  3. I need help, now with every flight the text "no flight plan" appears on all screens. Even when I obviously set the flight plan before the flight

    1. You need to import the flight plan either from simbrief or from game. IDX (index)-->FLT PLAN (second page).

  4. I am having a problem that the sim tells me that I can not use the comms because the radio is not switched on when I start from a dark cockpit.

  5. Thanks to the developer for this! The latest fix (.91) seems to have solved the issues I was having, and the plane feels much better to fly by hand too. I hope you can keep working on this, and updating it every time Microsoft changes things.
