What best describes the stabilized approach criteria by 1000 ft above the touchdown zone?

• A. By 1000 ft HAT: lateral and vertical profile established; airspeed within 0 to +10 kt of approach speed; thrust levers above idle; sink rate no greater than 1000 ft/min; high-sink-rate briefing if required; aircraft fully configured for landing and BEFORE LANDING CHECKLIST complete
• B. By 1000 ft HAT: appropriate approach airspeed established with gust factor applied
• C. By 1000 ft HAT: flight spoilers 0
• D. By 1000 ft HAT: the landing gear must be down and flaps set to landing

Answer: (A)

Stabilized approach criteria by 1000 ft above the touchdown zone mean the aircraft is on a controlled, predictable flight path with all key parameters settled for landing. The airplane should have its lateral path aligned with the runway and its vertical descent on a stable profile, so you’re not constantly chasing speed or altitude. The speed should be right in the approach band, typically within a narrow margin of the target approach speed, with a tolerance like 0 to +10 kt to ensure you’re neither underspeed (which can lead to a stall) nor overspeed (which can compromise control). Power must be above idle to maintain energy and provide adequate maneuvering margin for a go-around if needed. Descent rate should be limited to a safe level, such as no more than about 1000 ft/min, to avoid abrupt or excessive descent that could destabilize the approach. If you anticipate or experience a high sink rate, you’ll brief and manage it rather than letting it go unchecked. Finally, the aircraft must be fully configured for landing, and the Before Landing Checklist should be complete, so gear, flaps, spoilers, and other critical systems are set and verified. Other options miss essential aspects: focusing only on airspeed with gust factors omits the need for a stable descent path and proper configuration; specifying spoilers or implying gear and flaps without the full stabilized criteria doesn’t ensure a safe, manageable approach path.
