Abstract: A delimiter that can be arranged along the sides of a runway. The delimiter can be locked in an upright position for most normal operations. When the runway must be cleared of snow, an operator can lower the delimiters in place, either manually or by motor. After the runway has been cleared of snow, the delimiters can be raised again for use. Unlike the delimiters described above, these delimiters meet all aircraft regulation requirements. When collapsed, they do not protrude above the surface of the ground. The delimiters also have a shear mechanism that allows the raised portion of the delimiter to break off when struck. This shear mechanism protects aircraft by breaking away the upper portion of the delimiter.
