- This page refers to the concept and functionality of aircraft tuning. For the lists of individual parts in each game, see the subpages Tuning/Ace Combat X, Tuning/Ace Combat: Joint Assault, Tuning/Assault Horizon Legacy, and Tuning/Ace Combat Infinity.
Aircraft tuning is a gameplay feature introduced in Ace Combat X: Skies of Deception. This feature allows players to modify their aircraft's statistics and capabilities to match their playstyle.
In each of the games before Ace Combat Infinity that utilized tuning, the system works fairly similarly. Parts are unlocked by completing missions or achieving certain objectives, and must later be purchased. The different parts are divided into five categories: Engine, Wing, Armor, Weapons, and Cockpit. Only one part per category can be equipped. Most parts have both positive and negative effects on an aircraft; for example, a heavy armor upgrade will raise defense and lower speed and mobility.
In Ace Combat X: Skies of Deception, the tuning options were limited to fictional aircraft except the Fenrir. Ace Combat: Joint Assault and Ace Combat: Assault Horizon Legacy expanded upon this concept, allowing all purchasable aircraft to be customized.
Ace Combat Infinity
The aircraft tuning system in Ace Combat Infinity works much differently than in previous games. Rather than five categories, parts are now divided into three: Body, Arms, and Miscellaneous. In addition, rather than only allowing one part per category, all aircraft can carry a maximum of 7 parts regardless of what category they belong to. Each part also consumes a certain amount of "part slots" that corresponds to its category; for example, a Body part will consume a certain number of Body slots. Each aircraft has different part slots per category.
The majority of available parts only provide positive effects. However, some parts added in July 2015 and afterward have included negative effects as well.
Some parts have multiple variants in different sizes. The tiers are Small (S), Lightweight (LW/SS), Medium (M), Large (L), and Extra Large (LL). Each larger variant is more effective than the one before it but (with the exception of Lightweight) takes up more slots. Only one variation of a part can be equipped at a time.
The number of an aircraft's part slots can be increased by upgrading the aircraft or repeatedly sortieing with it. All aircraft receive +2 part slots for each category at Lv.6, +1 at Lv.15, and +1 at Lv.20.
After each sortie, the aircraft used is granted Part Slot Expansion Points. The amount depends on mission performance and can be greatly boosted by using Forced Sortie (using multiple fuels at once; see table below). Once the required amount of points for the next expansion is met, +1 slot is added to each category, and leftover points are counted towards the next expansion. The required points per expansion depend on the category with the least slots.
The maximum allowed part slots per category is 38 at Lv.1-5, 40 at Lv.6-14, 41 at Lv.15-19, and 42 at Lv.20. If an aircraft's maximum allowed part slots have been achieved, part slot expansion points per sortie are converted into credits at a rate of 10 credits per point.
The bonus multipliers for Part Slot Expansion Points by using Forced Sortie are as follows:
|Fuel Used||Part Slot Exp Points|
- The XFA-27's Scarface MBS upgrade in Ace Combat X is a clear homage to the plane's distinctive ability to simultaneously launch 4 missiles in Ace Combat 2, while the namesake comes from the main character of Ace Combat 2, Scarface One. Unfortunately, the part is only featured in Ace Combat X.
