What is the standard elevation for a runway numbered 6?

Runways are numbered based on their magnetic heading rounded to the nearest ten degrees. A runway numbered "6" faces approximately 60 degrees magnetic. The standard elevation of a runway is essential because it indicates the height above mean sea level (MSL) at which that runway is located.

For a runway numbered 6, the correct standard elevation is tied to specific airport data and topographic surveys that determine the elevation at which the runway is constructed. The choice of 173 feet MSL likely corresponds to a specific airport or runway where this elevation has been established, reflecting the actual survey data at that location.

Understanding the elevation of a runway matters for pilots, particularly during takeoff and landing phases, where variations in runway elevation can affect performance calculations, such as takeoff roll and climb-out, as well as altitude adjustments during approaches. The other choices represent different elevations that do not correspond to the standard established for runway 6 at the specific airport in question.
