What should pilots do if encountering undue delay after being told to "MAINTAIN RUNWAY HEADING"?

• A. Contact the RSU for clarification
• B. Initiate a turn toward the runway
• C. Immediately climb to 3000 feet
• D. Proceed to another runway

Answer: (A)

When pilots are instructed to "MAINTAIN RUNWAY HEADING," it means that they should keep their aircraft aligned with the runway's heading until further instructions are provided. If they encounter an undue delay after receiving this instruction, the appropriate course of action is to contact the RSU (Runway Supervisory Unit) or relevant air traffic control for clarification. This step ensures that pilots can obtain updated instructions and understand the reason for the delay, which is critical for maintaining situational awareness and safety.

By reaching out to the RSU, pilots can confirm whether they should continue holding their position or take any other actions, preventing any potential miscommunication or safety risks. Engaging directly with air traffic control is a fundamental practice in aviation, especially during periods of uncertainty or delay.
