A package is a group of one or more flights all working toward the same goal. The flights of the package can perform different tasks, at different times, and depart from different airports. For example, a strike mission attacking a factory will include a strike flight whose task is to attack the factory, but it can also include a SEAD flight to suppress any SAMs the package encounters, and an escort flight to protect the package from enemy aircraft. + +All of the planned ("fragged") packages of a coalition for the turn comprise the coalition's Air Tasking Order (ATO). + +## Mission timing + +Each package has an assigned time-over-target (TOT). The even corresponding to the TOT varies based on the flight. For strike and DEAD flights it represents the desired time for the weapon to hit the target (the AI cannot be given such precise attack commands, however), whereas for CAP it defines the start time of their patrol. + +Other mission waypoints, takeoff times, and mission start times will be planned based on the mission's TOT. Travel times to the target will be estimated, as will startup times and taxi times. + +Flights will have their takeoff delayed long enough that all flights can arrive at their target at the assigned time. + +## Rendezvous planning + +Some task types will rendezvous with the rest of the package before proceeding to the mission area. This is typically the case for strike/DEAD flights and their escorts. For these task types, additional waypoints will be added to the flight plan: + +A hold point will be added after the ascent point. Climb to altitude and orbit until the assigned departure time. Flights are planned with an assumed five minutes of hold time to allow for last minute preparations and to accommodate unexpected delays before takeoff. + +A join point is added after the hold point. At this point the flights will rendezvous with the rest of the package and head toward their target. The TOT of this waypoint is set the same for each flight. + +A split point is added after the egress point. This is where flights will split off from each other to head to RTB. + +## Task types + +Below is a list of all the currently available task types for flights. More will be added in future updates. Subscribe to [Issue 277](https://github.com/Khopa/dcs_liberation/issues/277) for updates. + +### BARCAP + +A BARCAP mission can be planned at any objective area, with the exception of front lines (for front line CAP, use TARCAP). Its purpose is to prevent enemy aircraft from entering the area. The flight will arrive at the target area at the package's TOT and begin a race-track pattern patrol and remain for a predefined amount of time (currently 30 minutes). The race-track will be oriented toward the nearest enemy airbase. + +### CAS + +A CAS mission can be planned at a front line. Its purpose is to provide support to ground forces. The flight will arrive at the target area at the package's TOT and begin searching for targets within a predefined range of the center of the front line. The flight will search for targets until it is either bingo or winchester. + +### DEAD + +A DEAD mission can be planned against enemy air defenses. Its purpose is to destroy enemy air defenses. The flight will rendezvous with the rest of its package and aim to have weapons on the target at the package's TOT. After releasing its weapons, the flight will RTB. + +### Escort + +An escort mission protects any other flights that are requesting an escort. Most mission types (CAP types are the exception) will request escorts for their mission. An escort will fly a flight plan similar to the rest of the package and RTB. + +Note that the escort flight will not remain in the target area even if the rest of the package does not complete its mission quickly. To assign long-term air-to-air defense, use a CAP flight. + +### SEAD + +A SEAD mission protects other flights from SAMs. In contrast to DEAD, it will engage air defenses near the target area and not just the target itself. The flight will rendezvous with the rest of its package and begin to search for and suppress any enemy air defenses within a predefined range. After releasing its weapons the flight will RTB. + +### Strike + +A strike mission can be planned against enemy ground targets. The flight will rendezvous with the rest of its package and release its weapons on the predefined location. Some bombers will carpet bomb an area in a single pass, but most will aim at multiple targets. After releasing its weapons, the flight will RTB. + +Note that strike packages are assigned coordinates to attack, not units. If the target moves the flight will not hit its target. + +### TARCAP + +A TARCAP can be assigned to a front line. TARCAP flights behave similarly to BARCAP except that it will only remain at the target area for as long as the members of the package that are requesting an escort plan to be there. If there are no other package members, the flight will patrol for a predefined amount of time (currently 30 minutes). \ No newline at end of file
