A220.127.116.11. Mooring Points for Areas Not Covered Above. The following installation options
should be used to provide mooring points for rotary-wing aircraft parked on the following
pavements: existing rigid pavement less than 150 millimeters [6 inches] thick; existing rigid
pavement in a cracked or deteriorated condition; new or existing flexible pavement; turfed areas;
and other areas where appropriate.
A18.104.22.168.1. Installation Option 1, Mooring Pad. This option is the preferred installation
method, and allows for placement of a new concrete pad with a minimum thickness of 200
millimeters [8 inches]. The size of the pad should be a minimum of 7.3 meters [24 feet] wide
by 13.4 meters [44 feet] long. The length and width may be increased to match the existing
concrete joint pattern. The mooring pad, with six mooring points, is illustrated in Figure
A12.7. The mooring devices should be installed as illustrated in Figure A12.1, and the concrete
reinforced as illustrated in Figure A12.5.
