What is the minimum runway width for CRJ 900 operations?

The minimum runway width for CRJ 900 operations is indeed 100 feet. This specification ensures that the aircraft can safely maneuver and operate during takeoff and landing phases, particularly given its size and wingspan. This width helps accommodate the necessary clearance for the wings and prevents any potential for wingtip collisions with obstacles that might be present near the runway. It also plays a critical role in maintaining safe aircraft handling margins during taxiing and maneuvering on the runway. Adhering to this minimum runway width is important for the operational safety and efficiency of the CRJ 900.
