Minimum Speed: 500 knots
Minimum Altitude: None
Extended use of the speedbrake at low speed or high altitude can cause your speed to drop to the stall point.
• You're flying straight and level (1).
• Extend your speedbrake. Notice how your speed drops to approximately 75 percent of its original level (2).
• Remove the speedbrake and notice how the plane quickly accelerates to its previous speed (3).
The speed brake is used often in combat to slow your speed in a hurry without slowing down the engine. It's frequently used to avoid overshooting an opponent. Once you've practiced this maneuver, you can try a speedbrake extension in a turn. Your speed will fall much faster due to the added drag of the turn.
Use the speedbrake to quickly decelerate.
