Working Title CJ4 v0.12.5

Welcome to the Working Title CJ4 v0.12.5. This version brings compatibility for MSFS Sim Update 4, as well as a number of other enhancements and small fixes, including traffic display (TFC) that will show the new SU4 SimConnect injected traffic from online services like VATSIM and IVAO. TCAS Control options are also available in the FMS, but TA/RA advisories have not yet been implemented.

In this release we also have a number of community submissions. Thanks to everyone, as always, for your contributions! We really love working with you all.


Please, please, please read the guide for instructions on using features. A lot of hard work went into writing the guide and the Discord channels are clogged with questions that are readily answered in the guide.



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.

⚠️ Known Issues

  • In the latest versions of Navigraph data, some “lettered” or non-runway-specific approaches now appear as something like RNAV A - 00 and do not allow the selection of a landing runway, preventing using the Approach Refs page - this is something we will be working to address in the future.
  • Some external applications that use the GPS/Flight plan SimVars may not function correctly or as expected when FP Sync is off.
  • Loading and saving flights can have bad results.
  • Custom liveries can render FADEC inoperative if they ship with a panel.cfg. Painters should reference our new Repainter’s Guide for solutions.
  • Autopilot modes cannot be triggered via key bindings or controllers and must currently be triggered in the cockpit with the mouse. External binding applications are adding support for LVars and HEvents. Used SimVars are documented in our Guide on SimVars.
  • Sometimes a heading to altitude instruction on takeoff will display further than the first RNAV fix on an RNAV departure procedure; in these cases the workaround is to cross-check the DP chart and remove the erroneous waypoint either by deleting the heading to altitude fix or dropping the first RNAV fix onto the magenta line in the LEGS page.
  • Due to sim autopilot bank rate limitations, the aircraft may overshoot on certain RNP approaches with tight turns. If you encounter this, we recommend hand flying the approach with the given lateral and vertical guidance.
