Hover Stability Airframe

 is a performance slot boost available to all and the Valkyrie. It is unlocked and upgraded using Certification Points.

While fitted, a hover stability airframe improves the aircraft's ability to get into and maneuver while hovering, improving the aircraft's airbrakes. Fighters receive an improvement to their vertical thrusters, whereas when fit to a Valkyrie the airframe also increases the aircraft's yaw rate and downwards thrust—the ability of the aircraft to dive. At rank 3, it also allows the Valkyrie to hover stationary without losing altitude.
