What is the minimum altitude at which the speedbrake must be extended?

Explanation:
Extending speedbrakes is all about energy management during descent. Increasing drag with the speedbrakes helps you slow to the desired approach speed without having to pull too much or lose lift. The procedure specifies that you must have the speedbrakes extended no later than 500 feet above the ground. This provides enough time and margin to decelerate and stabilize the approach before you reach the final segment. Extending them later than 500 AGL would give you insufficient drag margin to meet the target airspeed and descent profile, while extending them too early (well above 500 AGL) would unnecessarily blunt performance and complicate speed control on the approach. Deploying at or by 500 AGL keeps you in proper energy management for a safe, stabilized approach.
