What is the length of runway 18R at DFW airport?

The correct answer reflects the actual length of runway 18R at Dallas/Fort Worth International Airport (DFW), which is indeed 13,400 feet. This runway is one of the primary runways used for commercial aircraft operations at the airport, accommodating various types of aircraft, including larger international flights that require longer takeoff and landing distances due to weight and performance requirements.

Understanding the specific dimensions of runways is crucial for effective airport operations and aircraft management, including takeoff and landing procedures. The length of a runway must meet the operational needs of the airlines and aircraft using it, especially concerning safety and efficiency.

Additionally, the other choices reflect shorter or longer runway options that do not correspond to the specifications of runway 18R. For instance, while 10,000 feet and 12,000 feet might be typical for other runways, they are shorter than what is required for certain heavy aircraft operations. The 15,000 feet option exceeds typical runway lengths for commercial airports and does not apply to DFW's runway 18R. Thus, 13,400 feet is the accurate and relevant measurement for this particular runway.
