The LPWS defended altitude maximum is what value?

• A. 600 meters
• B. 1200 meters
• C. 900 meters
• D. 1500 meters

Answer: (C)

The idea being tested is how far a defense system can reliably detect and engage targets—the upper limit of its defense envelope. A defended altitude maximum comes from the system’s sensors and weapons working together: detect, track, and intercept must all be achievable with acceptable reliability. For this LPWS, that reliable ceiling is nine hundred meters. Up to that height, detection and engagement stay within the system’s capabilities; higher altitudes would push targets beyond what the sensors or interceptors can handle effectively. So, nine hundred meters is the maximum altitude the LPWS can defend.
