What is the turning radius required for a 180-degree turn in a CRJ900?

The turning radius required for a 180-degree turn in a CRJ900 is 80 feet. This value is crucial for pilots to know, as it directly impacts taxiing and maneuvering around airports, particularly in constrained areas or during ground operations.

Understanding the turning radius helps pilots plan their movements on the ground, ensuring they can safely navigate tight spaces without risking collision with other aircraft, taxiway boundaries, or terminal structures. An accurate turning radius is also essential for compliance with airport guidelines and regulations, facilitating safe and efficient aircraft handling.

The other options represent turning radii that are not consistent with the CRJ900's specifications and could lead to underestimating the space needed for a complete turn, which could contribute to potential safety hazards during ground operations.
