Which item is NOT part of the 1000 ft HAT stabilized approach criteria?

• A. Landing gear down
• B. Flaps in final landing configuration
• C. Sink rate greater than 1500 ft/min
• D. Thrust levers above idle

Answer: (C)

At 1000 ft above the threshold, a stabilized approach means the aircraft is in a proper landing configuration and prepared to continue smoothly to landing. That includes having the landing gear down and flaps set to the final landing configuration, and keeping the thrust levers above idle to maintain the appropriate airspeed and control authority for a safe approach. A controlled sink rate is also expected, but it’s limited to a practical, safe value—typically not something extreme. Describing a sink rate greater than 1500 ft/min does not fit the stabilization criteria, because such a high sink rate would indicate an unstable approach and would not be part of the acceptable stabilized profile. Therefore, the statement about a sink rate greater than 1500 ft/min is not part of the 1000 ft HAT stabilized approach criteria. The other items reflect the required configuration by that point: gear down, flaps in landing configuration, and maintaining thrust above idle to keep proper speed and control.
