Creating Custom Missions

YSFlight contains a mission definition that makes it possible to create a mission where an F-16 is on the runway and is being approached by a Mig-29 at 20 miles distance.

The definition file contains the following (without the comments). This file is inside the /ysflight/mission folder and is named f16vsmig29.yfs. The aircraft inside the file can be edited, saved as another file and it will appear in the menu.

The position of the attacking aircraft at present cannot be set.

The following modification moves the attacker more out to sea. The position CLOSEBY_GROUNDTARGET was added by inspecting the menu for create new flight. The underscore item has to be added, as it is not obvious.

Positions for starting the mission can be found by starting a flight and selecting the start positions, a cross highlights that location on the map. Locations can be chosen within that map or 'field' as it is called in YSFlight.
