If a runway distance remaining sign displays the number 6, how much runway is left for the pilot?

In aviation, runway distance remaining signs provide critical information to pilots about how much runway they have left on a particular runway. Typically, these signs display distances in hundreds of feet. Therefore, when a sign shows the number 6, it indicates that there are 600 feet of runway remaining.

The sign conveys this information clearly to ensure that pilots can make informed decisions regarding landing, takeoff, and any necessary abort procedures. The use of hundreds of feet allows for straightforward interpretation—each number corresponds directly to its value in hundreds. Hence, in this case, the number 6 signifies 600 feet of usable runway left.

Understanding this allows pilots to assess their landing and takeoff scenarios appropriately, ensuring safety and efficacy in their operations. The other options, while numerically valid, do not follow the standard practice of runway distance notation and thus would not be correct interpretations of the sign displayed.
