2026.8.20 V2.4.0

## FlyByWire A32NX (MSFS) INTERFACE SUPPORT [NEW]

- Added hardware interface support for the FlyByWire A32NX, covering the overhead panel (OVHD), the glareshield (GLARE — FCU, Captain and First Officer EFIS control panels, and the Captain and First Officer warning panels), the main instrument panel (MIP — ISIS, clock, landing gear panel and braking controls), the pedestal (PED — ECAM control panel, RMP 1 / 2, ACP 1 / 2, weather radar panel, ATC/TCAS panel, MCDU 1 / 2 and the throttle quadrant) and the flight controls (sidesticks / rudder pedals / nosewheel tiller / brakes). Hardware switches, knobs, encoders, displays, indicator lights and panel integral lighting are all synchronized bidirectionally with the virtual cockpit.

## Fenix A319 / A320 / A321 INTERFACE MODIFY

- Fixed a series of display faults caused by interruptions of the MSFS data stream in flight (RMP and FCU displays going blank or flickering, dimmed integral lighting, erratic indicator lights and similar symptoms).

- Fixed an issue where hardware switch positions (such as the ADIRS pushbuttons and the parking brake handle) were not automatically synchronized to the virtual cockpit when iFSim.Ready was started before MSFS and Fenix. Switch operations carried out while the connection is being established are no longer lost either.

- Fixed two issues with the barometric reference (BARO REF) window on the EFIS control panel: the First Officer window mirrored the Captain window and could not be set independently, and the value was displayed incorrectly in inches of mercury (inHg), previously showing a fixed value of about 0.30 instead of the actual setting such as 29.92.

- Fixed an issue where the RMP displayed the course (CRS) in an incorrect format in VOR and LS modes.

## ProSim A320 (Prepar3D) INTERFACE MODIFY

- Fixed an issue where the dimming controls had no effect on most cockpit lights and panel integral lighting.

Note:

1. We recommend installing the MobiFlight WASM (WebAssembly) module before driving the FlyByWire A32NX with iFSim.Ready hardware. Many of the cockpit switches, knobs and pushbuttons in the FlyByWire A32NX are operated through events and variables internal to the aircraft, which the standard MSFS interface available to external applications cannot trigger directly. The MobiFlight WASM module runs inside the simulator process and gives external applications a channel through which those operations can be carried out. Without it, a large number of controls on the overhead panel, ISIS, FCU and elsewhere will not operate the virtual cockpit — they produce no response at all and no error is reported, while every signal that works through the standard MSFS interface is unaffected. Please complete the installation before starting MSFS. This interface was developed and tested against the FlyByWire A32NX Stable release v0.14.0, and we recommend using that version or a compatible one.

2. This update modifies the signal mapping configuration files `profile/FenixA319_A320_A321.xml` and `profile/ProSimA320.xml`. The installer does not overwrite configuration files that already exist. If you have installed iFSim.Ready before, please back up and delete these two files from the installation directory before reinstalling; otherwise some of the Fenix and ProSim A320 fixes will not take effect.

## JeeHell FMGS A320 (Prepar3D) INTERFACE SUPPORT [NEW]

- Added full hardware interface support for the JeeHell A320FMGS aircraft model, covering the pedestal (PED), main instrument panel (MIP), glareshield (GLARE), overhead panel (OVHD), flight controls (sidestick / rudder pedals / nosewheel tiller / brakes) and circuit breaker (CB) panels.

- Communicates with FMGS through the JeeHell SDKPRO, and keeps an FSUIPC auxiliary channel for the few discrete commands that SDKPRO does not support (e.g. the flap handle detents).

## ToLiss A319 / A320 / A321 INTERFACE MODIFY

- Added support for the ToLiss A319 and A321 aircraft models. All three variants are now integrated into a single interface DLL (`Aircraft_ToLiss319_320_321_XPlane.dll`), and iFSim.Ready automatically detects which variant is loaded, with no manual switching required.

- Fixed an issue where `Aircraft_ToLiss319_320_321_XPlane.dll` would not automatically reconnect after X-Plane was closed and restarted.

- Fixed an issue where, with the aircraft on the ground, the pedestal trim wheel motor could be driven by mistake and even run all the way to the maximum nose-up (11UP) position. Auto-trim is now gated by the ECAM flight phase: the hardware trim wheel is driven only during the in-flight auto-trim phase, and no longer turns on the ground or during manual trimming.

- The parking brake handle in the virtual cockpit is now driven by both the hardware parking brake ON and OFF signals together, instead of by the hardware parking brake ON signal alone as before.

## Fenix A319 / A320 / A321 INTERFACE MODIFY

- Fixed an intermittent crash of iFSim.Ready caused by misaligned data received when the connection between iFSim.Ready and MSFS became abnormal or briefly dropped during flight.

- Fixed an issue where the Fenix interface module kept attempting to auto-reconnect while MSFS was not running, causing the memory usage of iFSim.Ready to grow slowly.

- Fixed an issue where the flap/slat handle detent was misidentified when the handle was moved slowly (the previous signal filtering would discard the final sample taken when the handle came to rest, leaving the detent stuck on the previous position).

- The parking brake handle in the virtual cockpit is now driven by both the hardware parking brake ON and OFF signals together, instead of by the hardware parking brake ON signal alone as before.

Note:

1. This update renames and adds Profile files: `FenixA320.xml` is renamed to `FenixA319_A320_A321.xml`, `ToLissA320.xml` is renamed to `ToLissA319_A320_A321.xml`, and `JeeHell_FMGS_A320.xml` is newly added. We strongly recommend uninstalling the previous version of iFSim.Ready before installing V2.3.0. If you have customized any profile, please back up and delete your old profile files first so that iFSim.Ready loads the latest default profile.

2. This update renames the ToLiss aircraft DLL from `Aircraft_ToLiss_320_XPlane.dll` to `Aircraft_ToLiss319_320_321_XPlane.dll`. The installer will automatically remove the legacy file.

3. To use the JeeHell FMGS A320 model, you must first install JeeHell A320FMGS and FSUIPC, then deploy the CModule (`iFSimReady_FMGS.dll`) bundled with iFSim.Ready into the FMGS Hardware Modules directory. See the accompanying setup manual for detailed steps.

## Fenix A319 / A320 / A321 INTERFACE MODIFY

- Fixed an issue where the pedestal TQ trim wheel rotated in a "stepped / not smooth" manner during auto-trim, noticeably less fluid than in V2.1.5 (V2.2.0 regression, customer feedback #4). The smoothness from V2.1.5 has been restored.

- Fixed an issue where the PED.TCAS CODE Display always showed 0000 instead of the actual XPDR CODE in the Fenix virtual cockpit (V2.2.0 regression, customer feedback #3).

## iFSim.Ready

- Fixed incorrect detent values for the throttle quadrant (TQ) left and right throttle levers (CL / FLX MCT detents) in the A320_calibration.xml and C919_calibration.xml calibration files shipped with the V2.2.0 installer (customer feedback #2).

Note:

1. This update modifies the `FenixA320.xml` profile, A320_calibration.xml and C919_calibration.xml files. If iFSim.Ready V2.2.0 is already installed on the machine, you must first uninstall iFSim.Ready V2.2.0 and then install iFSim.Ready V2.2.1, in order to pick up the corrected `FenixA320.xml`, A320_calibration.xml and C919_calibration.xml files.

## Fenix A319 / A320 / A321 INTERFACE MODIFY

- Integrated the Fenix A319, A320 and A321 aircraft models into a single interface DLL (`Aircraft_Fenix319_320_321_msfs.dll`). iFSim.Ready automatically detects which variant is loaded by reading the aircraft TITLE pushed from MSFS, no manual switching required.

- Added auto-resync of hardware switches, knobs and levers to the virtual cockpit after the aircraft is reloaded inside MSFS.

- Fixed an intermittent issue (especially during Fenix cold start and taxi-to-runway phase) where the entire pedestal backlight would suddenly turn off, dimming knobs would stop responding, and digital displays on the pedestal would disappear, requiring users to STOP and START iFSim.Ready to recover. The DLL now detects this condition automatically and self-recovers without any user action.

- Fixed an issue where pedestal dimming knobs (e.g. PED.INTEG LT MIP&PED Knob) would intermittently lose responsiveness during gameplay and require repeated operation to stay synchronized with Fenix.

- Fixed an issue where pedestal dimming knobs (e.g. PED.INTEG LT MIP&PED Knob) could not fully extinguish the hardware backlight when turned to OFF (a faint glow remained).

- Fixed intermittent failures of core pedestal controls (PED.PARKING brake, PED.FLAP Handle, PED.TQ MASTER / MODE) where users had to re-actuate the control to restore function.

- Fixed an issue where the "SPEED BRK" warning would intermittently pop up during Fenix flight while the speedbrake handle was at the RET (un-armed) position.

- Fixed an issue where the speedbrake handle had a "dead zone" against the virtual cockpit — the user had to push back slightly after pulling for both motions to align.

- Fixed an issue where pressing the OVHD.ADIRS.IR2 or IR3 button incorrectly affected the opposite IR switch in the virtual cockpit.

- Fixed an issue where the GLARE.EFIS L STD.PUSH / PULL display state was not latched after the button was released.

- Fixed an issue where the GLARE.EFIS R ADF1 / ADF2 / VOR1 / VOR2 three-position switches could not return to the OFF middle position after release.

- Fixed an issue where all overhead annunciator lights stayed on after exiting the OVHD.INT LT.ANN LT light test.

- Fixed value-range errors on the OVHD.AIR.AFT CABIN / COCKPIT / FWD CABIN cabin temperature knobs and the PED.CARGO AFT TEMP cargo temperature knob, which caused the virtual cockpit knobs not to track the hardware knobs.

- Fixed a value-range error on the PED.WX.TILT radar tilt knob.

- Fixed an issue where the GLARE.INTEG LT and GLARE.DISPLAY BRT knobs could not control the FCU integral panel backlight and digit brightness in the virtual cockpit.

- Fixed an issue where the MIP.CAPT / COPI.LOUD SPEAKER volume knobs could not control the corresponding virtual cockpit knobs.

- Fixed an issue where the MIP.CAPT / COPI.ND Outer knobs could not control the ND outer ring zoom in the virtual cockpit.

- Fixed an issue where the MIP.CAPT / COPI.CONSOLE FLOOR three-position switches could not change the floor light position in the virtual cockpit.

- Added the PED.GRAVITY GEAR EXTN Handle (gravity gear extension handle) signal interface.

- Added the PED.DOOR [OPEN] / [FAULT] cockpit door indicator interface.

- Fixed an issue where the OVHD.READING LT L / R reading lights did not follow the virtual cockpit reading-light brightness.

- Fixed an issue where the GLARE.READING LT L / R reading lights did not follow the virtual cockpit reading-light brightness.

- Fixed an issue where the GLARE.FLOOD LT MIP L / R and OVHD.FLOOD LT PED flood lights did not follow the virtual cockpit brightness.

- Fixed an issue where the GLARE.INTEG LT integral panel backlight did not follow the virtual cockpit brightness.

- Fixed an issue where the CONSOLE FLOOR LT L / R PWM did not follow the corresponding virtual cockpit switch position.

- Fixed an issue where the MIP.LDG DOWN red landing-gear warning light did not illuminate.

- Fixed an issue where the GLARE.FCU.ALT LVLCH LABEL and GLARE.FCU.LAT LABEL did not illuminate when the FCU was powered.

- Fixed an issue where the GLARE.EFIS L / R.QFE LABEL and OVHD.TOILET [OCCPD] / [DOT] did not illuminate during the light test.

Note:

- This update renames the existing "Aircraft_FenixA320_msfs.dll" to "Aircraft_Fenix319_320_321_msfs.dll". The installer will automatically remove the legacy "Aircraft_FenixA320_msfs.dll" file.
- This update modifies and extends some signal mappings in "FenixA320.xml". We strongly recommend backing up and deleting any existing customized profile so that iFSim.Ready loads the latest default profile (location: "<install dir>\profile\FenixA320.xml"). When iFSim.Ready installs or updates, it will not overwrite an existing profile file in the install directory.

Fixed an issue where X-Plane would crash after establishing a communication connection with iFSim.Ready in X-Plane 12.4.1 and higher version.

Note:
For this update, you must click the "Set iFSimReadyXPPlugin To X-Plane" button located on the OPTIONS -> SYSTEM page within iFSim.Ready to update the iFSimReadyXPPlugin plugin located in your X-Plane installation directory (X-Plane Install Path\Resources\plugins).
