Lesson Overview
Welcome to Module 6 of the Flight Sim Mastery Academy.
This module focuses on the iniBuilds A350 Airliner, a modern long-haul Airbus aircraft available for both Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024. The product includes detailed flight-management, navigation, display, performance and aircraft-system simulations, together with built-in SimBrief and Navigraph functionality.
The A350 is significantly more complex than a default aircraft. It contains:
- Large high-resolution cockpit displays.
- Advanced Airbus flight-management systems.
- Electronic checklists.
- An Onboard Information System, or OIS.
- Detailed fuel, electrical and hydraulic simulation.
- Long-haul performance calculations.
- Integrated charts and airport-navigation functions.
- High-resolution cockpit, exterior and cabin assets.
This lesson provides a practical gate-to-gate introduction. It does not attempt to reproduce every real-world airline procedure or abnormal checklist. Students will instead learn how to install the aircraft correctly, configure the essential options, complete a normal flight and test its effect on simulator performance.

STEP 1 – INSTALLATION
Installing the iniBuilds A350
1. Confirm Your Simulator Version
Before installation, identify whether you use:
- Microsoft Flight Simulator 2020.
- Microsoft Flight Simulator 2024.
- Both simulators.
The iniBuilds A350 is sold for both MSFS 2020 and MSFS 2024, but each simulator has its own package location and Community Folder. Do not manually move one simulator’s installed package into the other.
Students using both simulators should record:
MSFS 2020 Community Folder:
MSFS 2024 Community Folder:
Aircraft version installed in each simulator:
2. Create an iniBuilds Account
Create or sign into the official iniBuilds Store account.
Use the same account for:
- Purchasing the aircraft.
- Accessing iniManager.
- Downloading updates.
- Installing liveries.
- Accessing support.
Check that the correct email address and account are used before purchasing.
3. Install iniManager V2
iniManager is the official application used to install and update owned iniBuilds products. It provides one-click product installation and automatically manages new product versions when they are released.
Installation Procedure
- Close Microsoft Flight Simulator.
- Download iniManager V2 from the official iniBuilds website.
- Run the installer.
- Sign into the iniBuilds Store account.
- Open iniManager Settings.
- Allow the application to scan for simulator folders.
- Confirm the MSFS 2020 Community Folder.
- Confirm the MSFS 2024 Community Folder.
- Correct any custom paths manually if the automatic scan is wrong.
- Save the configuration.
Do not continue until the path shown for the selected simulator is correct.
4. Purchase and Download the A350
Inside the iniBuilds Store or iniManager:
- Locate the iniBuilds A350 Airliner.
- Confirm the product supports your simulator.
- Complete the purchase.
- Open iniManager.
- Select the correct simulator.
- Locate the A350 under owned products.
- Select Install.
- Confirm the installation location.
- Allow the complete download to finish.
- Do not launch the simulator while the installation is active.
The A350 contains a substantial amount of modelling, systems and texture data, so the download and installation may take longer than a simple aircraft package.
5. Confirm Adequate Storage
Before installing, confirm:
- The simulator is installed on an SSD or NVMe SSD where possible.
- The drive has sufficient free space.
- The Community Folder is not stored on a slow HDD.
- Windows has room for temporary installation files.
- The drive is not almost full.
Fast storage is especially valuable with a detailed wide-body aircraft because the simulator must load:
- Cockpit textures.
- Cabin assets.
- Exterior textures.
- Display files.
- Sounds.
- Systems modules.
- Livery files.
6. Aircraft Updates
iniBuilds distributes A350 updates through iniManager.
Recent updates have included refinements to:
- FMGS navigation.
- VNAV.
- Autoflight.
- ECAM.
- Thrust logic.
- Memory handling.
- WASM performance.
- General stability.
Update Procedure
- Close MSFS.
- Open iniManager.
- Select the correct simulator.
- Select the A350.
- Check whether an update is available.
- Read the release notes.
- Install the update.
- Confirm the new version number.
- Restart iniManager if required.
- Complete a short test flight before beginning a long-haul operation.
Do not update the aircraft immediately before an important VATSIM flight without testing it first.
7. Installing Liveries
iniManager can install supported A350 liveries directly into the simulator’s Community Folder. Official guidance recommends setting the correct simulator path and then selecting Install on the required livery.
Livery Installation Procedure
- Open iniManager.
- Select the correct simulator.
- Open the A350 livery section.
- Choose the airline and aircraft variant.
- Confirm simulator compatibility.
- Select Install.
- Allow the download to complete.
- Launch MSFS.
- Confirm the livery appears under the A350.
- Inspect it for missing textures or incorrect components.
Avoid:
- Installing the same livery twice.
- Keeping an older version active.
- Using an A350-900 livery on an incompatible variant.
- Copying MSFS 2020 liveries into MSFS 2024 without confirmation.
- Installing unrelated A350 liveries made for another developer’s aircraft.
8. Optional Livery and Cabin Components
The A350 supports aircraft-specific interior and exterior configurations associated with liveries. This can include airline-specific cabin or exterior equipment selections.
Because these options add extra assets, students should begin with:
- The default aircraft livery.
- The default cabin configuration.
- No optional custom cabin packs.
Once the aircraft is confirmed stable, add custom livery components individually.
9. SimBrief Aircraft Profile
Use the correct SimBrief aircraft type for the exact model being flown.
Typical A350 codes include:
- A359 – Airbus A350-900.
- A35K – Airbus A350-1000.
Use an iniBuilds-specific airframe when available.
Confirm:
- Aircraft variant.
- Engine type.
- Passenger configuration.
- Operating empty weight.
- Maximum weights.
- Fuel capacity.
- Units.
- Registration.
Do not use a generic A350-900 profile while flying the A350-1000. The variants have different:
- Weights.
- Capacity.
- Fuel burn.
- Take-off performance.
- Landing performance.
10. SimBrief Pilot Identification
Depending on the current integration, the aircraft may request the numerical SimBrief Pilot ID rather than only the account username.
Record both:
SimBrief username:
SimBrief Pilot ID:
The Pilot ID can be found in SimBrief account settings under the user’s SimBrief data.
11. Navigraph Integration
The A350 supports integrated SimBrief flight-plan retrieval and Navigraph navigation data. The product includes bundled base navigation data, while current database updates require a Navigraph subscription.
Navigraph authentication is handled through the integrated Navigraph system within the aircraft.
Setup
- Open the A350 OIS.
- Locate the Navigraph or account-linking page.
- Begin the authentication process.
- Follow the code or browser instructions.
- Authorise the A350.
- Return to the cockpit.
- Confirm charts and navigation services are available.
- Compare the aircraft AIRAC cycle with SimBrief.
An AIRAC mismatch can cause:
- Missing waypoints.
- Missing SIDs.
- Missing STARs.
- Invalid airway messages.
- Different approach procedures.
12. Community Folder Management
The A350 package and its liveries may add several folders to the Community Folder.
After installation:
- Record the main A350 package name.
- Record installed livery folders.
- Remove old versions.
- Check that no duplicate manual installation exists.
- Keep MSFS 2020 and MSFS 2024 files separate.
- Use Add-ons Linker only if the aircraft works correctly with linked packages.
- Do not rename core A350 package folders unless official instructions permit it.
For troubleshooting, create a dedicated profile containing:
- Core A350 package.
- One default or official livery.
- Required navigation integration.
- No unrelated airports or utilities.
13. First Installation Test
Load the aircraft using:
- A default airport.
- A large parking stand.

Confirm:
- The aircraft appears in the menu.
- The cockpit loads.
- The displays initialise.
- The OIS loads.
- The aircraft responds to switches.
- No WASM or system error appears.
- No CTD occurs.
Allow the aircraft several moments to initialise before interacting with it.
STEP 2 – CONFIGURATION AND NORMAL FLIGHT
Part A – OIS and Aircraft Configuration
14. Understanding the OIS
The A350 uses an Onboard Information System, or OIS, rather than a simple tablet.
It may provide access to:
- Aircraft settings.
- SimBrief.
- Charts.
- Flight operations.
- Payload.
- Fuel.
- Performance calculations.
- Ground services.
- Checklists.
- Navigation information.
- Aircraft configuration.
The OIS also supports deeper SimBrief flight-planning functionality through its Flight Operations Plan area.
15. Initial OIS Setup
Review:
- Units.
- SimBrief Pilot ID.
- Navigraph account.
- Brightness.
- Aircraft state.
- Performance settings.
- Cabin options.
- Ground services.
- Sound settings.
- Loading options.
Keep the same units across:
- SimBrief.
- OIS.
- MFD flight-management pages.

16. Performance Options
The exact options may vary by product version, but students should review any settings controlling:
- Cabin detail.
- Texture quality.
- Display quality.
- Display refresh.
- Exterior equipment.
- Interior equipment.
- Aircraft effects.
- Sound or cabin systems.
Begin with the default profile.
Change a performance option only when:
- The aircraft is GPU limited.
- VRAM usage is close to capacity.
- Displays are not updating smoothly.
- The cabin causes excessive loading.
- The airport and aircraft combination is too demanding.
Change one setting at a time.
17. Display Settings
The A350 contains several large, detailed displays.
Check:
- Display brightness.
- OIS brightness.
- Navigation-display range.

- Navigation maps active.
- Charts open.
- OIS open.
- External view.
This helps identify how much workload comes from cockpit display rendering.
18. Throttle Calibration
The A350 uses Airbus-style throttle detents.
Typical positions include:
- Reverse.
- Idle.
- Climb.
- Flex/MCT.
- TOGA.
Calibration Procedure

- Move them to CL.
- Save the climb detent.
- Move them to FLEX/MCT.
- Save the detent.
- Move them to TOGA.
- Save the final detent.
- Apply the configuration.
- Move through every position slowly.
Confirm the virtual aircraft displays the correct detent at each physical position.
Incorrect calibration may cause:
- Thrust levers failing to reach CL.
- Autothrust not operating correctly.
- FLEX or TOGA activating unexpectedly.
- Reverse thrust failing.
- Engines producing different thrust.
19. Flight Controls
Check:
- Pitch.
- Roll.
- Rudder.
- Throttle 1.
- Throttle 2.

Lesson Summary
You have now installed, configured, flown and tested the iniBuilds A350.
Remember:
- Use iniManager to install and update the aircraft.
- Keep MSFS 2020 and MSFS 2024 packages separate.
- Use the correct A359 or A35K SimBrief airframe.
- Keep the aircraft updated because recent versions include FMGS, autoflight, memory and WASM stability improvements.
- Authenticate Navigraph through the aircraft’s integrated system.
- Verify every imported SimBrief value.
- Calibrate Airbus throttle detents carefully.
- Use one coordinated fuel and payload system.
- Monitor the Flight Mode Annunciator after every automation selection.
- Manage long-haul fuel against the OFP.
- Expect the A350 to use more RAM, VRAM and processing power than a narrow-body aircraft.
- Test the default livery and airport before blaming the aircraft.
- Monitor memory throughout long flights rather than only at departure.
- Reinstall the aircraft only after controlled troubleshooting fails.
