World Update I: Japan Content

The centerpiece of patch 1.9.3.0 is the comprehensive overhaul of Japan, available for free through the in-game Marketplace after installing the base patch.

Enhanced Mapping: Features upgraded digital elevation mapping across the entire country.

3D Photogrammetry: Six cities received high-resolution 3D details: Tokyo, Sendai, Takamatsu, Tokushima, Utsunomiya, and Yokohama.

Hand-crafted Airports: Six airports were meticulously recreated: Hachijojima (RJTH) Kerama (ROKR) Kushiro (RJCK) Nagasaki (RJFU) Shimojishima (RORS) Suwanosejima (RJX8)

Landmarks & Architecture: Over 20 custom landmarks and points of interest (POIs) were added, including World Heritage sites, shrines, and skyscrapers, along with localized pagoda-style architecture.

New Activities: Includes new Landing Challenges set in Japan to test pilot precision. Core Game Improvements and Fixes

Beyond Japan-specific content, version 1.9.3.0 addressed several technical issues and added global enhancements: Microsoft Flight Simulator 2020 patch 1.9.3.0

Released on September 29, 2020, Patch 1.9.3.0 for Microsoft Flight Simulator

was a pivotal update that introduced the first major region-specific overhaul, World Update I: Japan, alongside critical stability and aerodynamic fixes. World Update I: Japan

The centerpiece of this patch was the free Japan content bundle, which required a separate manual download from the in-game Marketplace after the main client update.

Visual Enhancements: Introduced high-resolution digital elevation mapping across the entire country and new photogrammetry for six major cities: .

Handcrafted Locations: Added six handcrafted airports (such as Shimojishima Hachijojima

) and nearly two dozen landmarks, including Mt. Fuji and the Great Seto Bridge. Microsoft released Patch 1

New Activities: Featured three new Landing Challenges set at Japanese airports to test pilot skills in specific regional conditions. Aerodynamics and Engine Fixes

The patch addressed several fundamental flight model issues that had been present since the game's launch:

Ground Physics: Tweaked braking power to reflect more realistic braking distances and fixed collision bugs that occurred at negative altitudes.

Fuel Systems: Fixed a mass-calculation error related to fuel consumption for certain planes and resolved a crash issue for aircraft without a fuel leak system.

Gyroscopic Stability: Introduced a new setting in the SDK allowing for finer control over aircraft stability. General Improvements & Bug Fixes

UI Updates: The Sensitivity screen—which was previously bugged for many—was restored to work correctly. It also improved manual cache management and the liveries selection menu.

Environmental Tweaks: Improved ocean rendering (waves and foam) and edited water masks to display actual aerial imagery near shores, though some users reported these were still missing in certain areas. Managed Speed Descent: The "Open Descent" mode now

Weather: Resolved a bug where wind gradients would not function correctly near the ground in live weather and added more accurate lightning triggers.

Marketplace: Fine-tuned the rating system and added a version history for items, allowing players to see when third-party content was last updated. Community Feedback and Issues

While the update was praised for its visual fidelity, it faced criticism for introducing new bugs: AI Control Aircraft no longer works after 1.9.3.0 patch

Airbus A320neo

Managed Speed Descent: The "Open Descent" mode now respects the speed constraint entered in the MCDU (Multi-function Control and Display Unit).
Flap Load Relief: The aircraft will now automatically retract flaps to 1+F from 2 if exceeding VFE (Velocity of Flap Extension) by 5 knots, matching real Airbus logic.
ECAM (Electronic Centralized Aircraft Monitor): False "BRAKES HOT" warnings on taxi out are gone.

Pre-patch checklist (to avoid problems)

Back up community folder: copy %AppData%\Microsoft Flight Simulator\Packages\Community to another location.
Note any third-party addons and check their support pages for compatibility notes.
Update GPU drivers (NVIDIA/AMD) to latest stable release.
Save your flight (or fly back to an airport) before applying update to avoid corrupted quicksaves.

Overview

Patch 1.9.3.0 marked a significant step in Asobo Studio’s ongoing effort to stabilize and refine Microsoft Flight Simulator following its August 2020 launch. While not as large as the later “Sim Update” releases, this patch focused heavily on fixing critical bugs, reducing crashes, and improving overall performance, especially for users with lower-end hardware.

The Headline Numbers: What Changed?

Before diving into the weeds, here is the high-level summary of patch 1.9.3.0:

Version Number: 1.9.3.0
Build Number: 1.9.5.0 (in some launcher logs)
Primary Focus: Stability, UI fixes, Multiplayer synchronization, ATC logic
Aircraft Specifics: Boeing 747-8i "Dreamliner" fixes, Airbus A320neo system tweaks
Simconnect: Major overhaul for third-party add-on compatibility

World & Scenery

Elevation data fix: Resolved “cliff” and “floating airport” issues at several smaller airstrips, particularly in mountainous regions.
Photogrammetry streaming: Improved caching of Bing Maps data, reducing blurry textures on final approach.

Visual Fidelity: The World Update

While technically a separate download, Patch 1.9.3.0 was released in tandem with World Update VII: Australia. This update showcased the capabilities of the new patch.

Photogrammetry: Major Australian cities like Sydney, Melbourne, and Brisbane were rendered in stunning 3D detail.
Hand-Crafted Airports: Four new high-detail airports were added.
Landmarks: Famous sites like the Great Barrier Reef and Uluru received special attention.

This update proved that the engine could handle massive streaming data more efficiently than before, thanks to the optimizations in the patch itself.

Installation & verifying version

Launch the Xbox app (Windows Store) or Steam client you use.
Let the updater download and install automatically; do not force-close the launcher mid-update.
In the Sim, go to Options → General → About to confirm the build number (should read 1.9.3.0).

7. Airports & Scenery

Fixed runway elevation bumps at several hand-crafted airports.
Better AI aircraft parking logic (reduced clipping).
Improved night lighting visibility from altitude.
