Which condition will cause the landing gear aural warning to not be silenced when the SLAT/FLAP lever is in a landing position (5 or FULL)?

• A. SLAT/FLAP lever in 5 or FULL regardless of thrust lever position and radio altitude
• B. SLAT/FLAP lever in 0-4 with radio altitude below 700 ft AGL and thrust below mid-range
• C. SLAT/FLAP lever in 5 or FULL with radio altitude above 1000 ft AGL
• D. SLAT/FLAP lever in 0-4 with radio altitude above 3000 ft AGL and thrust high

Answer: (A)

When the SLAT/FLAP lever is in a landing position (5 or FULL), the system treats this as a critical phase for landing readiness. In this state, the landing gear aural warning cannot be silenced by changing thrust or radio altitude; it will remain audible until the gear is down and locked or you take the required action. This ensures the crew cannot mute a potentially dangerous reminder during approach and landing. The other conditions depend on altitude or thrust but do not override the hardware interlock that keeps the warning sounding when flaps are in landing configuration.
