## 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.
