What is the full meaning of the term RH in a runway context?

In the context of air traffic control and runway terminology, RH stands for Runway Heading. This designation is crucial as it refers to the compass direction in which the runway is oriented, measured in degrees from true north. For instance, if a runway is designated as 27, it indicates that the runway is oriented towards a heading of 270 degrees, or west.

Understanding runway headings is essential for pilots and air traffic controllers when it comes to takeoff, landing, and navigation within the airport environment. Accurate knowledge of runway headings helps in ensuring safe and efficient aircraft operations, particularly during critical phases of flight such as landing and taxiing.

Other options like Runway Height, Runway Hazard, and Runway Hub are not standard terms within aviation and do not accurately convey the meaning associated with runway designations, making them less relevant in this context.
