Which indication represents the runway heading in ATC terminology?

The indication that represents the runway heading in Air Traffic Control (ATC) terminology is RH. In aviation, runway headings are typically expressed in degrees, representing the compass direction a runway is aligned with. The prefix "R" stands for "runway," and "H" indicates "heading." Therefore, RH effectively communicates that it refers to the heading of the runway, which is crucial for pilots and air traffic controllers when discussing lift-off and landing directions, ensuring safe and efficient operations.

Other options do not correlate correctly with the terminology used in ATC. For example, RA might suggest something related to an approach (like "Radar Approach"), while RP is not commonly associated with runway metrics. RR could denote other operational aspects but does not specifically indicate runway heading. Understanding these distinctions is important for clear communication in aviation operations.
