Is there an MSFS 2024 mission editor, and how do I create missions?

Microsoft Flight Simulator 2024 has no simple player-facing mission editor for building Career jobs or challenges from its menus. On Windows PC, creators can use Developer Mode and the SDK to build packaged activities, but this is development work. For most simmers, a prepared flight plan and written objectives are the practical alternative.

What does MSFS 2024 offer instead of a mission editor?

MSFS 2024 separates playable missions from its content-authoring tools. The jobs displayed on the Career mission map belong to the simulator’s own progression system; players cannot open, edit or publish those jobs. Our explanation of how Career jobs, qualifications and progression work covers that system in more detail.

Developer Mode includes Project Editor and related SDK tools, but Project Editor is primarily a project and package manager—not an FSX-style, point-and-click mission builder. It can be used as part of an activity-development workflow where the installed SDK exposes the required activity type, assets and logic.

How do I create a custom mission with the MSFS 2024 SDK?

A structured custom mission requires a Windows PC development project built around an activity format supported by the installed MSFS 2024 SDK.

1. Define the mission before opening the tools. Write down the aircraft, starting position, route, weather, objectives, success conditions and failure conditions. Decide whether automated scoring or triggers are actually necessary; if not, a prepared scenario is much easier to maintain.
2. Install the SDK and enable Developer Mode. Follow our PC SDK installation and first-project workflow, then use the separate instructions for enabling Developer Mode and opening Project Editor.
3. Create a project and package. Use Project Editor to define the package, then choose an activity type that the installed SDK explicitly supports. If the SDK does not expose the kind of activity you need, adding invented metadata will not turn it into a Career mission.
4. Build the scenario. Set the route, departure state, environmental conditions and required scenery or objects. Add objectives, triggers and completion logic only through interfaces documented for that activity type; the available controls can differ between SDK releases and activity formats.
5. Control the dependencies. Prefer included aircraft and standard airports unless your audience is told exactly which add-ons are required. A mission tied to an unavailable aircraft, livery or scenery package may fail to load or behave differently for another user.
6. Test every branch. Start from a clean simulator session and verify normal completion, deliberate failure, restarts and different assistance settings. Check boundary conditions around altitude, speed, location and timing rather than testing only the ideal flight.
7. Build and test the installable package. The output package—not the editable source project—is what should be tested as a normal add-on. Resolve build errors and remove duplicate older builds before distributing it.

The SDK does not grant access to Career’s economy, company management, certifications, reputation or procedural job generation. Legacy FSX mission files are not a drop-in format for MSFS 2024 either.

Can I create an MSFS 2024 mission without the SDK?

Yes, but it will be a mission-like scenario rather than an automatically tracked activity. This is usually the better choice for training flights, group events and challenges that do not need scripted triggers.

• Specify the aircraft, airport, runway or parking position and payload.
• Provide a flight plan or route with any altitude and speed restrictions.
• State the weather, time, fuel limit and permitted assistance options.
• Write measurable objectives such as landing within a defined area, holding a target altitude or arriving with minimum fuel remaining.
• Include reset instructions in case a saved flight does not restore every cockpit or systems state correctly.

The same approach works well for instruction: our guide to building custom training exercises without a simple lesson editor explains how to package the briefing and flight setup clearly.

Why does my custom mission not appear or complete?

Most failed custom activities come down to packaging, dependencies or trigger assumptions rather than the route itself.

• Looking in the Career map: third-party activity packages do not become Career jobs or contribute to Career progression.
• Testing the source project: build the installable package and test that output, not merely the files in the development workspace.
• Using an unsupported activity type: Project Editor can package supported content, but it cannot make an undocumented activity format work.
• Missing dependencies: retest with only the required packages enabled and confirm that every referenced aircraft, object and scenery asset is available.
• A trigger never fires: check units, altitude reference, geographic radius, object names and the order of prerequisite conditions. Give location triggers enough tolerance for normal flying variation.
• Two builds are installed: remove obsolete copies before testing; duplicate package identities or stale files can make the simulator load the wrong version.

Can missions be created on Xbox or PlayStation?

No. The MSFS 2024 SDK and Developer Mode authoring workflow require the Windows PC version, and consoles cannot sideload arbitrary PC development packages. A package built for PC does not automatically become installable on Xbox, PS5 or PS5 Pro; console distribution requires a supported official route and the relevant platform checks.
