iniBuilds F406 Caravan II for Microsoft Flight Simulator 2020 & 2024 v1.0.2 Released

[mattY]

iniBuilds F406 Caravan II V1.0.2 Update 🛩️
This update brings an extensive set of improvements and fixes across all major systems of the F406 Caravan II, with a strong focus on autopilot behaviour, electrical and start-up logic. Key avionics and flight system bugs have been resolved, while art and sound assets have been refined. The EFB also sees some welcome enhancements, including a new night mode checklist and additional user-requested features. 

This update can be downloaded via the iniManager.

Quality-of-Life Changes
V1.0.2 delivers several quality-of-life enhancements aimed at improving the overall user experience. Autopilot behaviour has been significantly refined, addressing multiple logic and mode interaction issues for smoother, more predictable operation. Engine start procedures have been brought closer to real-world behaviour, with corrected ITT response, igniter logic, and sound feedback. In addition, a few sound inconsistencies have been addressed, including improved switch interactions and engine startup audio. 

Autopilot Logic Updates
Autopilot logic has been updated to more accurately reflect the modeled system’s real-world behaviour. Notably, approach mode now requires the aircraft to be established on the localizer before capturing the glide slope, bringing the procedure in line with proper operating technique. Back course mode has also seen improvements, with updated logic and a more reliable controller to ensure accurate tracking.
Additionally, the initial autopilot engagement now captures and syncs the current vertical speed correctly, resulting in a much smoother transition into automated flight. The vertical speed controller itself has also been refined for improved stability and responsiveness.



Sound Refinement
Our partners at Echo19 have been hard at work refining the overall sound experience, taking on board feedback from the community. In this update, you’ll notice improvements to the engine start-up sequence and beta range sound profile, both of which now feel truer to life. Alongside these, a number of smaller adjustments have been made throughout the soundscape to boost immersion and bring the audio closer to the real aircraft.

Start Logic Updates
The engine start behaviour and sequence have been reworked to more accurately reflect real-world PT6 operations. This includes improved simulation of hot start scenarios, cooling dynamics, and the ignition sequence, complete with the distinctive ITT rise that defines PT6 engine starts. These changes bring a more authentic and rewarding engine start experience for those who enjoy flying by the book.

Thanks for your support on this project, it's an incredibly fun aircraft to work on and truly something different to what we're usually used to. Be sure to keep those user reported bugs and feedback coming in so we can continue to push updates that ensure real life accuracy!
