Which magnetic heading corresponds to RWY 31 at EFTA?

The correct magnetic heading corresponding to Runway 31 at EFTA is 299°. This is determined by analyzing the runway designation, which typically comprises the runway's magnetic azimuth rounded to the nearest 10 degrees.

Runway numbers are derived from the magnetic heading, with runway 31 indicating that the runway is oriented approximately towards 310 degrees magnetic. When rounded to the nearest whole number, the azimuth is represented as runway 31. The magnetic headings in the choices provided are 119°, 199°, 219°, and 299°, of which only 299° aligns with the standard convention regarding runway designations.

In the context of maneuvering and navigation, understanding magnetic headings is crucial for pilots to ensure proper alignment during takeoff and landing, as well as in maintaining situational awareness during flight operations around the airport environment.
