Gear up warning conditions include altitude below 10,000 ft, airspeed under 210 KCAS, and throttles below what percent RPM?

Gear up warning conditions include altitude below 10,000 ft, airspeed under 210 KCAS, and throttles below what percent RPM?

• A. 90% RPM
• B. 96% RPM
• C. 92% RPM
• D. 98% RPM

Answer: (B)

Gear up warning logic is designed to alert you when you’re in a low-altitude, low-speed phase and there’s a realistic risk you haven’t completed a safe gear retraction. The warning uses three inputs: your altitude, your airspeed, and how hard the engines are working (throttle position). The idea is to avoid nuisance warnings during high-thrust maneuvers while still giving you a heads-up if you’re near the ground with insufficient power to climb or accelerate. The throttle threshold here is 96% RPM. If you’re below 10,000 ft and your airspeed is under 210 KCAS, and your throttles are below 96% RPM, the system will generate the gear warning. Once throttles are at or above 96%, the warning is suppressed, because you could be in a high-thrust situation (like a go-around or climb) where delaying gear retraction is acceptable or expected, and a warning would be a distraction. The other numbers would shift that balance either too early or too late: a much lower threshold would produce warnings too often at modest power, while a higher threshold (like 98%) would fail to warn in scenarios where high thrust is not present but gear might still be down. The 96% threshold best matches the goal of warning you when you’re near the ground with limited thrust, without interfering during high-thrust situations.
