Working Title CJ4 v0.12



VNAV Climb should now be working correctly - we know that we've warned many people in past versions to turn it off if it isn't working, but at this point we believe it works as designed. As a refresher, in the CJ4, VNAV in climb is NOT A PATH. It simply provides protection for the pilot to not exceed an AT or AT OR BELOW constraint in the departure procedure. The protection exists ONLY for waypoints that are loaded into the FMC as part of a DEPARTURE PROCEDURE. If you add other waypoints beyond the DP, those constraints will not be respected as climb constraints.


  • Enabled APPR mode for ILS when tuned in PFD even when an approach is not loaded in the FMC.
  • Added custom vertical autopilot to manage altitude capture and hold modes. (note: the ALT button is now tied to H:WT_CJ4_AP_ALT_PRESSED and the emissive lvar is L:WT_CJ4_ALT_HOLD)
  • Added altitude capture for PTCH mode.
  • Added altitude capture for TO/GA modes.
  • Enabled ability to arm LNAV on the ground and set activation at 400' AGL.
  • Fixed bug with not being able to turn off the Flight Director when FMA modes are annunciated - the FD button will now disable all modes when being turned off, as long as the AP is not on.
  • Fixed bug that prevented VNAV button press from being read when APPR mode was active - now it is only force disabled when GP/GS have been captured and those are the active vertical modes.


  • Added PITCH REF value to the FMA when in PTCH mode.
  • PFD Baro preset bug fixed where improper units would sometimes display with the baro preset window open.
  • Fixed bugs with selected altitude < 0 or > 45,000; these values will not display AND the simvar values will not exceed those limits (you can't get stuck below 0 anymore).
  • Removed inaccurate feature of resetting the FMA modes upon landing - they will now remain in the last selected modes until the FD is turned off.


  • Improved map/terrain mask (thanks Slip!).
  • Improved ROSE/ARC display to better reflect the real aircraft.
  • Improved min wind vector/speed display.
  • Fixed bug where DES waypoint would appear even after it had been passed sometimes on the map.
  • Improved gps track bug on MFD/PFD and enable during ground ops.
  • Added ability for FMS Text VNAV window to display climb data even when no descent/arrival is picked, and also to show arrival/TOD data after climb constraints have passed.
  • Fixed the Range Banana (altitude intercept arc) on the PFD/MFD to only display the point where the SELECTED altitude will be intercepted, not the VNAV altitude.


  • Added runway slope calculations to Takeoff and Landing Ref pages - you can now enter a slope and the relevant TOFL/LFL number will adjust accordingly.
  • Added landing factor distance selection on Approach Ref page - you can now select the landing factor.
  • Added ability to enter custom/new pax weight on PERF INIT page using format "/XXX" or "5/XXX" and the pax weight value is persistent.
  • Added ability to enter Gross Weight on PERF INIT page to override ZFW and/or Pax/Cargo inputs.
  • Fixed bug where the final approach fix calculation in LNAV sometimes chose the missed approach waypoint as the FAF.
  • Fixed bug that sometimes caused the departure runway to be undefined (black FMC screen) after flight plan import.
  • Adjusted DIRTO and Vertical Direct page and capabilities to fix bug not allowing a second vertical direct, not allowing a vertical direct to a current direct to waypoint.
  • Added ability to select any vertical waypoint with a constraint for a direct to; when constraints are A/B or A/ the altitude targeted will be the ABOVE value.
  • Fixed bug causing VREF/VAPP display error in FMC in certain circumstances.
  • Removed departure runway altitude from flight plan and LEGS page.


  • Fixed bug that would prevent a climb in cases where there is no SID, but a STAR exists and has constraints.
  • Adjusted VNAV FMS Text window to display descent data as soon as the last departure constraint is passed, instead of waiting until the departure procedure has been completely flown.
  • Fixed bug with missing some A/B or A/ constraints in the first descent segment in some rare cases.
  • Changed behavior of path smoothing to cause the first descent segment to always be at the requested VPA in the VNAV DESCENT setup page.
  • Fixed bug with VNAV calculations after a DIR TO.
  • Adjusted behavior after FPLN change is made that adjusts the PATH; if the new PATH causes an out-of-activation range problem, AP mode changes to PTCH.
  • Fixed bug where after PATH arms in an ABOVE PATH intercept situation, PATH won't disarm even if you deviate from intercept parameters.
  • Extensive debugging and fixing of obscure/non-normal cases.


  • Adjusted idle thrust.
  • Adjusted 75% thrust error in thrust table.


  • Adjusted behavior of the panel light knob to replicate the function of the knob in the real aircraft - full on is DAY setting, and this is the ONLY setting to get daytime charts.

Working Title CJ4 v0.11.3


  • Fixed bug with Pilot Waypoint storage that could cause errors for users adding waypoints to the data store for the first time
  • Fixed missing STAR transition legs when selecting a VFR runway for landing instead of a published approach
  • Fixed a bug with the autopilot update loop that could occasionally cause LNAV or VNAV to stop responding
  • Made adjustments to LNAV turn anticipation in certain turn types
  • Fixed bug that prevented the correct hold entry type from being updated when changing inbound course and turn direction
  • Fixed bug where AP dives to pre-select altitude when VNAV is disabled while in PATH mode
  • Fix behavior when a flight plan change causes PATH recalculation while in PATH mode - will now go to ALT and attempt to re-arm PATH

Working Title CJ4 v0.11.2


  • Implemented charts dark/night mode (activated when panel lights are off or at full [daytime mode] and are otherwise night mode)
  • Added ability to store up to 20 pilot waypoints (IDX->DATABASE)
  • Added ability to type pilot waypoint idents in LEGS, DIR and FPLN pages

  • Fixes for TOD problems, including showing a TOD when in an approach and missing when in cruise
  • Fixed VNAV FPTA error that sometimes could cause LNAV to stop responding
  • Added CHECK SPEED message that will show when your speed is >20kts than the current restriction (remember speed constraints are not automatically loaded from nav data and must be manually entered)
  • Further enhancement of terrain colors for the TERR map option; adds curve points above and below aircraft based on aircraft AGL altitude.
  • Cleanup of some small FMC bugs, including missing Working... messages for some screens.
  • Improved duplicate detection methods when importing flight plans (fewer duplicates will flag)
  • Removed 'select waypoint' page being triggered during an import if there are no exact duplicates
  • Refined TOD rounding on MFD in VNAV WINDOW

Working Title CJ4 v0.11.1

Known Issues

  • PITCH mode will not level off at an altitude and it can have some quirky behaviors. This is currently a sim AP issue.
  • 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. You must uninstall them or remove their panel.cfg from the livery folder. This is a limitation of the Asobo livery system.
  • Autopilot modes cannot be triggered via keybindings or controllers and must currently be triggered in the cockpit with the mouse. External binding applications are adding support for LVars and HEvents.
  • 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 handflying the approach with the given lateral and vertical guidance.
  • If for whatever reason, you find that VNAV is not behaving as expected, try and turn it off and on again.

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.

Navigational items not currently implemented but scheduled for future updates

  • Holds and procedure turns
  • FMC INTC CRS capability
  • VNAV Vertical Direct-To Fix
  • Manual Point/Bearing or Point/Bearing/Distance fixes
  • Route offsets
  • LNAV/VNAV approaches. Currently all RNAV approaches use LPV in APPR mode due to no minimums type information in the available navdata.
  • Going direct-to on the LEGS page does not give you an EXEC option, it will automatically execute.


Installation is easy, simply copy the workingtitle-aircraft-cj4 folder inside the zip file to your MSFS Community folder. Important: Due to some file location changes in the latest MSFS version, it is mandatory that you fully delete the previous workingtitle-aircraft-cj4 folder before copying this release.

  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.

    1. u dont read manuel u dont hear atc

  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.

  6. I am having a devil of a time with flight plans and need some help:

    - How do I get FS2020 to load a file plan from a file on disk and consider it to be IFR? It always wants to convert everything it loads from a file to a VFR Direct flight plan. I'm using .PLN files generated by a converter (fpc.kognise.dev) using input from SkyVector Garmin .FPL files that SkyVector exports. Even if I change the XML value making it "IFR", FS2020 still loads the plan as VFR Direct and there are no usable leg waypoints. And once loaded, you cannot convert a VFR plan to IFR using the World Map interface. It always computes a new route when you select either of the IFR options. That's not what I want.

    - How do I convince the CJ4 FMS to load an IFR flight plan from a file (it will be the same file FS2020 loads)? From the Route Menu, the <FPLN LOAD (GAME) key seems to be taking its input from whatever FS2020 has in its little brain, and when FS2020 thinks it has a VFR Direct flight plan CJ4 doesn't load any leg waypoints only the starting and ending airports. None of the other keys on the Route Menu are active, so there doesn't seem to be a way to load a flight plan file from the disk.

  7. pos ils autopliot dont work.just like hole simultator is bugy pos game for idiots

  8. Well kudos to all for the great work ! Becoming one of my favorite airplanes. It does seem a bit quirky in terms of the AP, since there is a 2nd NAV button... Im so curious about how MSFS seems not to have assignments (keystrokes) for the equivalent VS as the COCKPIT VS button. It would be great to know how to assign a KB sequence to turn on the 2nd NAV and the VS bug from MSFS button assignments. EX; when I use the rotary knob to select VS on Bravo Throttle I dont get the VS BUG in the Citation CJ4? I have to select VS in the cockpit. I tried changing the binding to other VS related but no luck... I also notice discontinuity in almost every flight plan, thats new for me, Who in the AIR FORCE came up with that word (just continuity would work), Im just sayin.
