What is the correct procedure to follow when encountering a steady green light while on taxi?

When you encounter a steady green light while taxiing, it signifies that you are clear for departure from the runway. This light indicates to the pilot that they have received explicit clearance from air traffic control to take off, confirming that the runway is clear and it is safe to proceed with the departure.

This procedure is crucial for safe operations at the airport and ensures that pilots follow proper communication protocols with air traffic control to avoid any potential hazards. In this context, the other choices do not reflect the correct action for a steady green light during taxiing. Preparing for takeoff or positioning the aircraft for takeoff would be premature actions without the explicit clearance indicated by the green light. Also, simply proceeding onto the runway does not adequately account for the necessary communication with air traffic control. Therefore, understanding the meaning of a steady green light is essential for safe flight operations and adherence to standard protocols.
