What is the actual heading of runway 36 at Oshkosh/Wittman Regional (OSH) airport?

The correct answer reflects the runway's heading in degrees, which is typically expressed in whole numbers representing its magnetic orientation. Runways are designated by the number that corresponds to their heading rounded to the nearest 10 degrees. Since runway 36 indicates a heading of 360 degrees, this means the runway aligns nearly directly with magnetic north.

The option listed as 360° is conceptually the same as stating the heading as 0° (north) because they point in the same direction. However, in aviation, runways typically drop the '0' for simplicity, hence runway 36 is the designation used rather than runway 360 or runway 0.

Thus, the heading of runway 36 at Oshkosh/Wittman Regional Airport is indeed 360°, which is the appropriate way to understand that runway's orientation. The other options either represent incorrect values or inaccurately convey what the runway's heading number conveys in its standard nomenclature.
