Aircraft Tree

The Aircraft Tree is a system of tuning featured in Ace Combat Infinity. It allows players to "research" further technologies to unlock aircraft or aircraft parts.

Description
The tree is split into ten tiers, ranging from Tier 0 to Tier 9. Tiers are locked depending on your rank: Further information on these ranks is unavailable, pending the game's full release.
 * Warrant Officer - Up to Tier 2
 * Second Lieutenant - Up to Tier 4

Technologies in further tiers also require certain items from previous tiers to have been fully researched and then purchased before research can begin on these higher-tier technologies. These pre-requisites are listed below, but Infinity does provide a visual diagram to assist in seeing the pre-requisites for certain techs.

Technology

 * -|Tier 0=All items in this tier are automatically unlocked and purchased at level 1.


 * -|Tier 1=All items in this tier require the F-4E Phantom II and the Su-25TM Frogfoot to be purchased. Since they are given to the player for free, all items in this tier are automatically unlocked, but must be researched before they can be purchased and used.
