When you close the throttle plates on the engine it can no longer pull air in large amounts and the fuel injectors shut off to cut most. At around 70 psi you will get the low air audible warning. Air brakes and spoilers are flight control surfaces that create additional aerodynamic drag when deployed into the path of air flowing around the aircraft.
