220.127.116.11. Semi-Circular Pad. At aviation facilities used by large cargo aircraft and Aerial Ports
of Embarcation (APOE) and Aerial Ports of Debarcation (APOD), the hazardous cargo pad is a
semi circular pad as shown in Figure 6.26. The semi-circular pad is adequate for aircraft up to
and including the dimensions of the C-5.
18.104.22.168. Other Pad Size. The hazardous cargo pad geometric dimensions as shown in Figures
6.25 and 6.26 are minimum requirements. Hazardous cargo pads may be larger than these
dimensions if the design aircraft cannot maneuver on the pad. Sources for obtaining information
concerning minimum turning radii for various aircraft is presented in Army ETL 1110-3-394,
Aircraft Characteristics for Airfield-Heliport Design and Evaluation.
6.12.4. Access Taxiway. An access taxiway will be provided for access from the primary taxiway
to the hazardous cargo pad. The taxiway should be designed for the aircraft to taxi into the
hazardous cargo pad under its own power.
6.12.5. Tiedown and Grounding Points. Tiedowns/mooring points/tiedown mooring eyes must be
provided on each hazardous cargo pad. Grounding points must be provided on each hazardous cargo
pad. Tiedown and grounding points are further discussed in Attachment 12.
