What is the minimum runway width for CRJ-700/900 & ERJ?

• A. 75 ft
• B. 80 ft
• C. 90 ft
• D. 70 ft

Answer: (B)

Runway width must provide enough clearance for the aircraft’s wingspan plus margins to prevent edge contact during takeoff and landing. For CRJ-700/900 and ERJ aircraft, the wingspan and required side clearances mean the smallest width that safely accommodates these jets is 80 feet. Runways narrower than that (such as 75 or 70 feet) don’t leave enough lateral room for the wings and nacelles, especially under crosswind or steering corrections, while a wider runway (90 feet) would still be acceptable but isn’t the minimum.
