Which runway designators does EFTA utilize?

The correct answer pertains to the specific orientation and numerical designation associated with the runway system at EFTA, which is the Al Bateen Executive Airport in Abu Dhabi, UAE. In aviation, runway designators are determined based on the compass heading that the runway aligns with. Each runway is given a number that corresponds to the nearest ten-degree magnetic azimuth, rounded down.

Runway 13 corresponds to a magnetic heading of approximately 130 degrees, and Runway 31 corresponds to a heading of about 310 degrees. This pairing indicates that the two runways can accommodate traffic in opposite directions, which is essential for managing airport operations and ensuring safety. This is particularly relevant for an executive airport like EFTA, where traffic patterns might require efficient use of available runways for landing and takeoff.

In contrast, the other runway designators listed in the choices pertain to different compass headings and do not align with what is utilized at EFTA. Therefore, recognizing the specific runway designations associated with Al Bateen Executive Airport is crucial for understanding how airport operations are structured and managed in relation to its geographic orientation.
