According to Prop. 1 of Air Power, what does controlling the air typically lead to?

Controlling the air is fundamentally linked to achieving dominance over the battlefield, and one of the primary outcomes of air superiority is the ability to control surface operations. This dominance allows ground forces to maneuver and operate with reduced threat from enemy air assets. When the airspace is secure, land units can effectively conduct their missions without fear of aerial attacks disrupting their operations. Furthermore, this control enables better coordination and support from air assets, enhancing overall operational effectiveness. Securing air control essentially creates a favorable environment that impacts a wide range of military operations on the ground, making it a vital strategic objective in warfare.
