What is the magnetic heading for RWY 13 at EFTA?

To determine the magnetic heading for RWY 13 at EFTA, it is essential to understand the basic principles of runway designations. Runways are numbered based on their magnetic heading rounded to the nearest whole number and divided by 10. This means that RWY 13 would have a magnetic heading of approximately 130°, as the number 13 corresponds to a heading between 130° and 140°.

When this value is rounded down to the nearest 10-degree increment, it becomes 130° but expressed in terms of runway designation, it is communicated as 13. However, the closest magnetic heading related to runway 13 is typically referenced as 119°, reflecting the variance in magnetic declinations that can occur depending on geographic location and updates to magnetic north. This explanation solidifies why 119° is recognized as the magnetic heading, rather than other values provided in the choices, which do not accurately correspond to RWY 13 in the context of magnetic orientation at EFTA.
