What is the immediate action on an asymmetric approach when runway obstruction occurs after ACA(H)?

• A. You are committed to land
• B. Acquire new speed and altitude
• C. Proceed to alternate runway
• D. Review weather and continue

Answer: (A)

When one engine is inoperative on final, energy and performance margins are tight. ACA(H) marks a point where you’ve assessed the approach and the available energy for a go-around if needed. If a runway obstruction is encountered after this point, the ability to perform a safe missed approach is severely limited because the aircraft’s climb capability with one engine out is reduced, and you don’t have much height to safely execute the maneuver or clear the obstacle. The obstacle clearance path for a go-around cannot be guaranteed from this stage. Therefore, the safest immediate action is to commit to landing on the available runway if it is in sight and you can maintain the required approach criteria. Trying to go-around or divert at this moment would introduce a high risk of collision with the obstruction or loss of control due to asymmetric thrust and limited performance near the ground.
