What are the normal minimum runway length?

• A. 5400 ft
• B. 4800 ft
• C. 6000 ft
• D. 5200 ft

Answer: (A)

Normal minimum runway length is the planning figure used to ensure safe takeoff and landing under standard conditions, reflecting the runway space required for typical aircraft performance with standard margins. Five thousand four hundred feet is the baseline that accurately covers the majority of regional jet operations at normal weights and temperatures, providing enough room for the aircraft to reach takeoff speed, meet climb and obstacle clearance requirements, and stop safely if needed. The other lengths either don’t offer sufficient space for safe performance at common weights, or are longer than what’s usually necessary for normal operations, so they aren’t the standard baseline.
