TM 1-1500-250-23 CHAPTER 2 HARDWARE AND AIRCRAFT REQUIREMENTS 2-1. Grid Pattern Layout and Mooring Point Strength. The grid pattern layout illustrating the 17 to 20 foot on center mooring points is depicted in figure 2-1. a. This pattern readily accommodates all the heli- copters in the army fleet and should be used as the stan- dard for new mooring installations. b. The strength of each mooring point should be capable of reacting to the design loads depicted in fig- ure 2-2. 2-2. Mooring Pad Marking. Marking the moor- ing pad to properly position the aircraft is recom- mended if the pad is to be used exclusively for one type of aircraft. 2-3. General Tools and Equipment. a. All aircraft will use polyester rope for rotor blade tie-down. Refer to table 2-1. (1) Tie-down OH-58D as specified in the ap- propriate aircraft Technical Manual. (2) Tie-down OH-58A/C as specified in the appropriate Technical Manual, except that two main ro- tor blade tie-down boots are required. (3) Tie-down AH-64 as specified in the ap- propriate Technical Manual. Ensure that the ropes are strong enough to allow the main rotor blades to be se- cured at the required locations. (4) Tie-down UH-60 as specified in the ap- propriate Technical Manual. (5) Tie-down AH-1 as specifiated in the ap- propriate Technical Manual. (6) Tie-down UH-1 as specifiated in the ap- propriate Technical Manual, except that a forward main rotor blade tie-down strap is required. (7) he-down CH-47 as specifed in the ap- propriate Technical Manual. b. Tie-down and Mooring Equipment. Refer to table 2-1. (1) Acquisition and maintenance of all re- quired tie-down and mooring equipment is the re- sponsibility of the aviation units. (2) The identified chain and chain adjuster shall be used as the primary mooring equipment for all helicopters when parked at their home installation and army policy (per paragraph 1 –6) requires moor- ing. Exceptions to the use of mooring chains is only approved under special circumstances where chain has proven to be undesirable such as the crossover mooring on the CH-47D. (3) Mooring chains and chain adjusters are not considered flyaway equipment. The 10,000 pound capacity polyester mooring strap with ratchet buckle, NSN 5340-01-233-3063, is the identified fly- away which may be used when aircraft deployed away from their home station require mooring and chains are not available. The CGU-lB, 5000 pound capacity ny- lon tie-down strap, NSN 1670-00-725-1437, is only authorized when hard stand mooring points available and the field mooring kit is used. are not Change 3 2-1
