In the example scenario, on which runway did Lear 102KM land?

• A. Runway 28R
• B. Runway 28L
• C. Runway 9
• D. Runway 18

Answer: (A)

Runway numbers show the magnetic direction of the landing approach, and letters like L and R identify which of parallel runways with the same heading you’re using. A designation of 28 means the runway is oriented roughly toward 280 degrees. When there are two parallel runways, they’re labeled 28L and 28R to tell them apart—the R being the right-hand one when you’re facing toward the 280-degree direction.

In this scenario, the Lear 102KM landed on the right-hand runway with that 280-degree heading, so the 28R designation is the correct match. The other options would correspond to different headings (for example, 090 degrees for a 9 heading, or 180 degrees for a southbound approach) or, in the same heading, the left-hand counterpart, which doesn’t fit the described landing.
