What information do Runway Distance Remaining signs provide?

Runway Distance Remaining signs are critical for pilots during takeoff and landing, as they provide information about the distance left on the runway in increments of 1,000 feet. This helps pilots make informed decisions regarding their operations during these critical phases of flight. Knowing how much runway remains allows for better assessments of stopping distance, particularly for aircraft that are landing or those preparing for an aborted takeoff.

The other options present information that is not indicated by Runway Distance Remaining signs. While distance to runway exits, time remaining before takeoff, and indications of weather conditions are important for flight safety and operations, they are communicated through different signs, markings, or instruments and are not the primary function of the Distance Remaining signs. This specificity is what makes option A the correct answer.
