The information given on this page and other linked pages which is specific to <strong>Missions</strong> is <strong>obsolete for Microsoft Flight Simulator 2024</strong>. It will be updated in the future.

This section details the different files related to the files required by Microsoft Flight Simulator 2024 to create flight plans and other files required by aircraft, SimObjects, and for missions.

The files covered in this section are:

-   [Flight Plan XML](flight-plan-xml-properties/) (`*.PLN`)

-   [FLT Files](../flt-files/flt-file-properties/) (`*.FLT`)

-   [Mission XML](mission-xml-properties/) (`*XML`)

-   [Weather XML](weather-xml-properties/) (`*.WPR`)

-   [Event Trigger XML](event-trigger-xml-properties/) (`*.XML`)

{{< callout context="note" title="NOTE" icon="outline/bulb" >}}

Many of these files will be compiled into [SPB files](../../devmode/editors/project-editor/file-formats/spb-files/) when the package is compiled.

You can also find examples of the contents of these files from the following page:

-   [Flight, Weather and Event Examples](flight-weather-event-examples/)

-   [Training Flights](../../samples-tutorials/tutorials/creating-a-flight-training-mission/)


This section also covers the creation of packages for **World Photographer** missions through the use of *Travelbooks*:

-   [Travelbook Setup (World Photographer Missions)](travelbooks/travelbook-setup/)

-   [Travelbook Page XML Properties](travelbooks/travelbook-page-xml/)

-   [Travelbook Objective XML Properties](travelbooks/travelbook-objective-xml/)


### Note on Custom Content Mission Order

When you have custom content missions, for example a tutorial that is comprised of multiple missions, the order in which these are displayed to the user is important. As such, it's important to be aware of the way that files are ordered using the following simple rules:

-   Missions that have the [difficulty](../../../cfg-files/aircraft.cfg/#difficulty) parameter are going to be listed first in the list, where:
    -   These missions are sorted with the missions that have the lowest difficulty being llisted first. So, for example, a mission of difficulty 1 will above a mission of difficulty 2.
    -   If two missions have the *same* difficulty, then they are sorted alphabetically using the **translated** name of the mission.

-   Missions with *no* difficulty parameter setup will be at the *end* of the list after those that do have the parameter. These missions will be sorted *alphabetically* using the **translated** name of the mission.
