#Experimental Drag and Drop
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.

Update/Changes in V0.75 (DEC 25, 2020) - Merry Christmas
: (Improvement) Legacy flight model reworked.
: (Add) FMC - ECON SPD, TRANS ALT, TRANS SPD Function added
: (Add) FMC - VNAV - ' Extra Page ' - TOD Calculator page added
: (Fix) FMC 2, 3 interation issue after patch 1.12.13.0 fixed.
: (Fix) Upper EICAS - Wrong Stabilizer trim indicators fixed.
: (Fix) FMC black issue related A320NX mod fixed.
: (Revised) Default cockpit view setting revised.
: (Revised) Default cruise altitude setting revised.
: (Revised) FMC pages revised to support new patch version.
: (Revised) File size and version information revised.
: (Miscs) Now you can choose normal version / loading screen version.
: (Miscs) Loading screen before flight changed.   - Loading Screen Version Only!

Update/Changes in V0.74 Hotfix 1 (DEC 05, 2020)

- MOD Folder and Zip file renamed
  : I realized the current mod folder name is too long and it can cause an unzip error in some cases.

Update/Changes in V0.74 (DEC 02, 2020)
- (Improvement) Autopilot - Longitudinal stability about the glideslope approach improved.
- (Improvement) Autopilot - Airspeed control and accuracy improved.
- (Improvement) Autopilot - ILS auto-approach and landing performance improved.
- (Add) FMC - FMC COMM and PROG pages added.
- (Adjustment) Some flight characteristics adjusted.
- (Miscs) File size and version information revised.


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. :)

---------------------------

Known Issue in V0.75 
- Turn On/Off Logic of Mode Control Panel Logic (Turn on/off light and etc) is now working properly
  : After update 1.12.13.0 patch, Asobo's default MCP logic is changed. It's under investigating now.

  • Version 0.72 November 25, 2020

    *Changelog - V0.72

    - (Improvement) Autopilot - Altitude control improved
    - (Improvement) Autopilot - VS mode accuracy improved
    - (Fix) Autopilot - Pitch Oscillation Behavior after update #7 Fixed (1.11.6.0)
    - (Adjustment) Autopilot - Parameters of Longitudinal Attitude adjusted for update #7 (1.11.6.0)
    - (Adjustment) New Fuel Consumption Parameters adjusted for testing
    - (Adjustment) Some flight characteristics adjusted.

    After update #7 (1.11.6.0), my previous rework version may be caused pitch oscillation behaviors in some flight condition. I think this unintended behavior is caused from game-core design changes in update #7. Especially, 747-8i's stabilizer deflection speed from autopilot's trim control is drastically increased by update #7.
    Therefore, I redesigned my autopilot control models and other characteristics. :)

    Hey Kairi. Liking the mod so far. Just curious, is there somewhere in the FMC does it show remaining trip details? The progress page seems wonky still, but that info would be helpful. Thanks.

    Thanks for your comment.
    You mean trip details like a remained distance and waypoints?
    In my case, I had referred that informations from LEGS and PROG pages of FMC with ND (Navigation Display, right-side of PFD). :)

    Thanks for the reply. I was thinking something more along the lines of entire trip, something that tells me distance until runway???

    flight was fine until final approach when it went totally off the rails trying to find the LOC. Fix for this? or anyone else had the same issue?

    Thanks for your comment.
    About LOC off track issue...other user report about similar issues in a few weeks ago, and I was already tested some conditions.
    Have you installed the A320NX mod in your community folder?
    I think ' Waypoint.js ' and ' WaypointLoader.js ' files in A320NX mod cause that issue because they use old version before the DEC 2020 update. (It located in A32NX/html_ui/Pages/VCockpit/Instruments/FlightElements/ folder.)

    Nice work, any chance of IRS Alignment etc in the next update? That's the only thing I miss really from Salty's 747.

    Thanks for your comment.
    My major is aerospace engineering, not programing or coding. Therefore, I'm studying about javascript code and others in my spare time, but still very very novice stage. This means I can't guarantee about IRS simulation.
    Honestly speaking, now I'm working on my flight model overhaul to improve flight experience.

    Its amazing!

    Only problem i have is when the plane is near fully load(98% cargo and 50% fuel) when im at 38k feet or more,the AOA is near 9 degrees,do you know if its a bug? Thanks for the mod :D

    Thank you for your comment.
    Higher AOA in high altitude is normal behavior, because air density of high altitude is lower than low altitude. I'll explain about this for you.
    The level flight means lift generation is same as its weight, and it expresses as equation 1,

    L = W ---------- (equation 1)

    Also, lift is related to air density, speed, wing area, lift coefficient, and this can express as equation 2,

    L = 1/2 * ρ * v² * S * CL ---------- (equation 2)

    If airplane maintains level flight, it also can express as equation 3,

    W = L = 1/2 * ρ * v² * S * CL ---------- (equation 3)

    In 38,000 feet like your situation above question, weight (W), speed (v), wing area (S) is same, but air density is 27.1% level sea level, and it means ρ above equation decreased to 0.27ρ. It means overall lift is decreased and it can't maintains its level flight.

    W =/= L = 1/2 * 0.27ρ * v² * S * CL ---------- (equation 4)

    If you can't change your weight, speed and wing area condition, you need to increase another aerodynamic parameter like lift coefficient (CL), and it related with shape of airfoil and angle of attack. This can explain why AOA is higher than low altitude for maintaining level flight.

    However, I will improve my 747-8i flight model more better, because now I have understood better about the flight model structure by experience about my F-15 rework.

    I stumbled upon this mod while browsing earlier and thought I'd give it a whirl. Well - Salty might have added some cockpit functionality and 1 or 2 other things, but this mod actually makes the 747 flyable! I tested with a very short hop from Manchester to Gatwick from Cold & Dark, every step of the flight went smoothly and I never once had any issues with my FMS, LNAV, VNAV, etc. I am really impressed, thanks for your efforts! I read in an earlier comment that you said you're quite a novice with programming - I really hope you are able to further develop or engage with maybe other developers to piggyback off your first stab, because I think you've nailed a lot of the problems currently experienced on the default aircraft. Looking forward to future updates :)

    Thanks for your comment. Now I studying about javascript code to add FPV(Flight Path Vector) symbol functions and fix or rework about other functions what relate to flight of PFD screen in my spare time. Honestly speaking, I'm pretty stuck in this progress now and need more time to real life, but I'll doing my best for 747. Salute! :)

    Thanks for your comment. You mean checklist functions in the toolbar? If it is, you can use default 747's checklist function with my mod.
