The Tactical Datalink (also known as datalink or Data Link) system is a gameplay mechanic featured in Ace Combat Infinity. Its usage must be activated by an AWACS unit, and it activates specific bonuses for players depending on their equipped effect if they fly closely to their allies.
The datalink system works similarly to the Friendly Assist System from Ace Combat: Assault Horizon. While editing an Aircraft Set, players can choose a datalink effect that, when flying closely to another player while datalink is available, will take effect for that player. At the same time, the other player who is linked will have their own effect according to their Sortie Set.
The range of datalink connection is not certain, but modifications such as the Link Communications High Output Antenna can be used to increase the range.
In campaign missions including and after Great Migration, and in multiplayer missions, a notification will appear near the bottom of the HUD indicating that the player must standby for datalink connection. Once an AWACS activates the connection, the player must fly closely with an allied unit. While a datalink connection is active, the notification will inform the player who they are connected to, and the radar will show a blue line going from the player's aircraft to the aircraft of the player they are connected to.
