If suitable landmarks are not available for a departing aircraft, what must happen before takeoff?

• A. Wait for clearance
• B. Ensure the runway is clear
• C. Wait until the preceding departure has become airborne
• D. Contact the tower for verification

Answer: (C)

In the context of air traffic control and departing aircraft procedures, if suitable landmarks are not available for navigation, it is essential to wait until the preceding departure has become airborne. This ensures that the runway is clear and that it is safe for the next aircraft to take off. This practice enhances safety by preventing potential conflicts on the runway and provides a systematic flow of departures.

Waiting for the preceding aircraft to take off provides a clear indication that the runway is both unoccupied and that the airspace ahead is clear, allowing subsequent departures to proceed safely. It is crucial in maintaining orderly traffic flow and minimizing the risk of collisions or accidents during the departure phase, especially when visual references (landmarks) are limited.
