What is the minimum altitude for flight spoiler deployment?

• A. 500 ft AGL
• B. 1,000 ft AGL
• C. 1,500 ft AGL
• D. 2,000 ft AGL

Answer: (B)

Spoilers are used to spoil lift and add drag, which changes the aircraft’s flight path quickly. Deploying them at a safe minimum altitude gives you enough room to manage airspeed, maintain control, and, if needed, execute a go-around or adjust your descent without getting into trouble close to the ground. One thousand feet above ground level provides this safety margin: deploy them lower, like five hundred feet, and you’ve got far less time and room to recover if the maneuver doesn’t go as planned. Higher altitudes, such as one and a half or two thousand feet, aren’t the minimum required; they’re more conservative margins, but the question asks for the minimum altitude needed.
