Under Stabilized Approach Criteria, stabilization is evaluated from how many feet above TDZE?

Under Stabilized Approach Criteria, stabilization is evaluated from how many feet above TDZE?

• A. 1000 feet
• B. 500 feet
• C. 2000 feet
• D. 0 feet

Answer: (A)

The key idea is when an instrument approach must be in a stable state on the final approach. Stabilized by about one thousand feet above the touchdown zone elevation means the aircraft should be on the correct flight path, in the proper landing configuration, and with appropriate airspeed and descent rate by the time you reach roughly one thousand feet above the TDZE. This gives you a safe window to verify everything and make any needed adjustments, or to execute a go-around if you aren’t stabilized. TDZE is the runway’s touchdown zone elevation, so being stabilized by that height ensures you can land smoothly and safely. The other options don’t align with this standard threshold: they’re either too low to allow safe correction, or unnecessarily high.
