What is the minimum centerline separation required for simultaneous takeoffs from parallel runways?

• A. 1000 feet
• B. 1500 feet
• C. 2500 feet
• D. 3000 feet

Answer: (C)

The minimum centerline separation required for simultaneous takeoffs from parallel runways is 2500 feet. This distance is established to ensure safe operations by accounting for the potential effects of wake turbulence generated by departing aircraft. Wake turbulence can cause significant disturbances, especially to smaller aircraft that may follow closely behind larger ones. By maintaining a distance of 2500 feet between the centerlines of parallel runways, air traffic control can effectively mitigate the risks associated with wake turbulence, thereby enhancing safety for all aircraft involved in takeoff operations. This requirement is particularly critical when considering the types of aircraft utilizing the runways and their operational characteristics.
