If you haven't done part 1 of this tutorial, you can find it here.

Step 1: Setting up the file structure

Before we start creating our mission, we need to get some files into place. Copy one of the default missions from the Missions folder into your own folder. Delete the .sbp .flt and .wx files. Edit the .htm files and update the images. These files contain all the background info you'll see in the FSX mission menu and the kneeboard.

Step 2: Creating the mission

In FSX bring up the object placement tool. Create a new mission and give it a name. Add 'ScenarioMetadata under 'MissionObject'. Fill in the values as explained in the video.

Step 3: Creating a flight

Create a new flight and initialize it how you want to start your mission (i.e. select the right aircraft, airport and weather). Save the flight.

Copy the .flt and .wx files into your mission folder and add the following entry to the .flt file.

[ObjectFile]
File=YourMissionName

Congratulations. You have just created your first mission. It doesn't do much yet, but it's all downhill from here!
