I was release my works at MSFS forum before, you can check the thread :
https://forums.flightsimulator.com/t/autopilot-and-flight-model-reworks-for-boeing-747-8i/317624

This Boeing 747-8i mod contains
- Autopilot control function model rework
- Flight Characteristic adjustment
- Fuel Consumption adjustment 
- Ground Handling (about taxing) fix
- Landing/Taxing Light fix and (Slightly) improvement
- Start condition changes (about autopilot setting for mid-air depature)


The autopilot control function model was reworked to fix some annoying issues (e.g. zig-zag swaying and poor tracking performance and autopilot induced oscilliation behavior) of Asobo's default model and improve its performance (flight route rendezvous/tracking, attitude change and recovery). Also, flight characteristics and stability was adjusted to improve its handling, and fix inconsistency between modern and legacy flight model setting.

- (Improvement) Autopilot - Longitudinal stability about the glideslope approach improved.
- (Improvement) Autopilot - Airspeed control and accuracy improved.

Important 1 : Use with MODERN FLIGHT MODEL for AUTOPILOT reworks. My autopilot rework is suitable for modern flight model setting. But, also I tweaked flight characteristics for manual flight. (for both modern / legacy flight models)

Important 2 : ' Assisted Yoke ' option can be caused unintended behavior. Please turn off this option. (OPTIONS - ASSISTANCE - PILOTING - Assisted Yoke)

Important 3 : Do not use with another 747 mods, it can cause unstable or strange behavior. My mod NOT support another 747 mod compatibility in the present version. (Because my mod is under development progress now)

Important 4 : You can't use 747 related landing challenge with this rework mod because landing challenge compares scores between players. Also, my reworks provide different flight characteristics and stability (Maybe this is easier and comfortable than default 747). I think this is unfair to landing challenge competition, and can cause controversy about cheating or something. So, I change my mod settings. (Only for my mod, not a permanent change. You can use 747 landing challenge with default 747.)


- Installation : Just unzip and copy & paste into community folder.
(If it successfully installed, you can see the different words including ' by Ph.D KAiRi ' on the white sticker which is located on the left front side of cockpit windshield.)

- How to check the version after installation
   : Press MENU button in FMC and Press VERSION button.

- You can check the details in readme file.

Thanks for everyone and have a nice fight. :)
