Learn how FSX missions use objectives and triggers, where built-in and downloaded missions live, and why a mission may not appear in the menu.
FSX missions are scripted flights that combine a briefing, objectives, triggers, voice prompts and success or failure conditions. In FSX and FSX: Steam Edition, open Missions from the main menu to browse the included scenarios. More missions can be added as downloads, usually under the simulator’s Missions folder.
Where do I find built-in missions in FSX?
Built-in missions are selected from the Missions option on the FSX opening screen, rather than through Free Flight.
- Open Missions: Select the Missions section from the main menu.
- Browse or filter: Use the category and skill-level filters to narrow the list, or clear them if a mission appears to be missing.
- Read the briefing: Check the aircraft, location, estimated duration and any special instructions.
- Start it from the mission screen: This loads the flight together with its objectives, triggers, dialogue and scoring logic.
The included selection depends on the edition and expansion content installed. FSX: Steam Edition includes Acceleration content, while a boxed Standard or Deluxe installation without Acceleration may not meet the requirements of every mission.
How do FSX missions work while you are flying?
An FSX mission works by loading a prepared flight and an accompanying script that monitors what happens in the simulator.
Triggers can react to entering a defined area, reaching an altitude, waiting for a set time, operating a control or completing another objective. Those triggers can display instructions, play audio, change weather, move AI traffic, introduce failures or advance the mission to its next stage.
A mission is therefore not just a saved .FLT file. The saved flight supplies the starting situation, but the mission XML and supporting files provide the objectives and event logic. Opening the flight file directly through Free Flight may load the aircraft and location without starting the actual mission.
Why can a mission fail after a safe landing?
Landing safely does not guarantee success because FSX checks the scripted completion conditions, not simply whether the aircraft reached the ground.
You may need to land at a specified airport, stop inside a marked area, set the parking brake or wait for the final instruction. Skipping a waypoint, changing aircraft, using slew mode or moving too quickly through a timed section can prevent an expected trigger from firing. When guidance seems to stop, review the objective text and return to the last instructed position rather than heading straight for the destination.
Where are FSX mission files stored?
Mission content is stored inside the simulator installation, normally in this relative location:
<FSX installation folder>\Missions\<category>\<mission folder>\
The precise installation path varies because both boxed FSX and Steam libraries can be installed on different drives. For Steam Edition, use Steam’s command for browsing the game’s local files and open the Missions folder from there. If boxed FSX and Steam Edition are both installed, check that you are looking at the folder belonging to the copy you actually run.
A complete mission folder may contain a saved flight, weather data, mission XML, briefing material, images and audio. Some packages also include separate reward or supporting files whose destinations are specified by the author.
Where can I download more FSX missions?
Additional scenarios are available in our collection of downloadable FSX missions, covering training flights, emergencies, challenges and story-driven operations.
Packages vary considerably. For example, this guided scenario with custom audio, objectives and map support shows how much more a mission can contain than an ordinary saved flight. Check each download for required aircraft, scenery and Acceleration content before installing it.
Installation normally means extracting the package and placing its mission folder beneath the correct category, but optional rewards and supporting files may have separate destinations. Our step-by-step mission installation instructions cover the full procedure without duplicating it here.
Why does an installed mission not appear?
A missing mission is usually caused by its folder structure, filters, requirements or installation location.
- The archive is still compressed: FSX cannot load a mission directly from a ZIP or similar archive.
- There is an extra nested folder: Some archives unpack into an outer package directory. The folder containing the actual mission files must sit at the expected level beneath
Missions. - It was copied into the wrong FSX installation: This is common when boxed and Steam editions coexist.
- A menu filter is hiding it: Clear category and skill filters before reinstalling anything.
- Required content is absent: A mission built for Acceleration or a particular add-on may not load correctly without it.
- It is only a saved flight: A package without mission scripting belongs under saved flights rather than the Missions menu.
Do not place mission folders in SimObjects\Airplanes or Addon Scenery. Those locations are for aircraft and scenery, not mission scripts.
Can I create my own FSX missions?
You can create FSX missions, but doing so requires more than saving a flight because objectives, triggers and events must be defined in mission XML.
Creators commonly prepare the starting flight, position mission objects, build trigger logic and then add briefings, audio and optional rewards. Our tutorial explaining FSX mission structure and event logic is the appropriate starting point for understanding how those parts fit together.
