Go-around should be initiated at what altitude when an abnormal condition is detected?

• A. 2,000' AGL
• B. 1,000' AGL
• C. 500' AGL
• D. 0' AGL

Answer: (B)

Go-around decisions are made to ensure you have enough airspace and performance margin to safely execute the missed approach. Initiating at 1,000 feet AGL gives you a stable window to configure the aircraft, establish the proper climb, and follow the missed-approach procedure without rushing or risking collision with terrain or other traffic. If you wait lower, there’s less room to recover from a misconfiguration or power issue and to establish a safe climb path. Ground contact is already possible below that altitude, so continuing descent with an abnormal condition becomes risky. Higher than 1,000 feet can unnecessarily delay the required maneuver and reduce the chance to regain a stabilized approach; and going all the way to the runway (0 feet AGL) would defeat the purpose of having a safe, controlled escape path.

So, 1,000 feet AGL provides the practical balance of prompt action and enough margin to fly a safe missed approach.
