What is the magnetic heading for RWY 31 at EFTA?

The magnetic heading for Runway 31 at EFTA is 299°. This value is derived from the runway designation, which is based on the magnetic azimuth rounded to the nearest 10 degrees. In this case, the runway number '31' indicates that the centerline of the runway is oriented toward a magnetic heading of approximately 310°. However, because runway designations are rounded to the nearest number that could represent the general direction, Runway 31 corresponds to a heading of 310° which, when rounded, still conveys that the aircraft taking off or landing is generally heading towards that bearing. Hence, the closest magnetic heading that corresponds to Runway 31 is indeed 299°, reflecting a common approach to referencing airport runway headings.

Understanding runway designations in terms of magnetic headings is essential for pilots in order to align properly when taking off or landing, ensuring safe and efficient navigation in the airspace.
