Aircraft statistics

Aircraft statistics refer to each game's way of measuring the performance of playable aircraft. Measuring methods differ between games; for example, Ace Combat 04: Shattered Skies measures stats with bars, Ace Combat 5: The Unsung War indicates statistics with points in a 0-99 scale, and both Ace Combat 3: Electrosphere and Ace Combat 6: Fires of Liberation measures statistics with a pentagon and hexagon respectively.

Parameters[]

The Ace Combat series' games uses different parameters to measure each aircraft's statistics. Below are the most common parameters in the series.

Speed refers to an aircraft's forward movement speed. It is known as Power in Air Combat, Ace Combat 2, and Ace Combat 3: Electrosphere.
Defense measures an aircraft's damage threshold. The higher the stat, the more damage will be taken by the aircraft. Attackers often excel at defense.
Mobility indicates an aircraft's movement capabilities in a 3D space. This parameter is unrelated to Stability.
Stability measures the aircraft's capability to fly at low speeds without entering a stall. Aircraft with a high Stability parameter can fly at speeds of 120 mph without stalling. It also indicates how much the aircraft moves after the player stops giving a directional input. The higher the stability, the less the aircraft moves afterward.
Air-to-Air refers to an aircraft's air combat capabilities. The aircraft can lock-on airborne targets faster the higher the stat. In Ace Combat Infinity, the higher the stat, the more damaging the standard missiles can achieve on aerial targets.
Air-to-Ground indicates a particular plane's capability at air strikes. The aircraft can lock-on surface targets faster the higher the stat. In Infinity, the higher the stat, the more damaging the standard missiles can achieve on ground targets.

Attack is a stat exclusive to Air Combat (called Offense there) and Ace Combat 3. It refers to the aircraft's overall combat capabilities, which determines aircraft's missile carrying capacity.
Fire Power is a new statistic introduced in Ace Combat: Assault Horizon. Presumably, it refers to the aircraft's combat effectiveness similar to the aforementioned "Attack" stat.
Climbing capability is a parameter exclusive to Ace Combat 2, which measures how high an aircraft can go before stalling.
