Prior to creating an entry for the "Simulated Flight", you will need to create a Logbook aircraft instance for the Simulator. You can do this by navigating to More > Logbook > Aircraft in ForeFlight Mobile and then tap on the + symbol at the top right.
By default, when the aircraft is created the Equipment Type will be listed as "Aircraft"
Tap Equipment Type and change the "Aircraft" Equipment Type to one of the Simulator options:

Once all details for the newly created simulator have been filled out, you can then create the flight entry and reference the Full Flight Simulator (FFS), Flight Training Device (FTD), Basic Aircraft Training Device (BATD), or Advanced Aviation Training Device (AATD) in the Aircraft field.
