carriage. The 25.4 mm (one inch) clearance applies to the minimum clearance between all stores and mechanisms that move during normal aircraft operation, including bomb doors (and their swept volumes), door actuator systems (and their swept volumes), spoiler systems (and their swept volumes), and any other applicable mechanisms which may contact the stores in the bay. There should also be a 25.4 mm (one inch) clearance between the above aircraft parts and the volume stores sweep out during a trapeze suspension translation or a rotary suspension rotation.
4.3.3.2 Store to store clearance.
Same as 4.3.2.2.
4.3.3.2.1 U.S. Navy requirement.
The minimum requirement for clearance between internal stores is 63.5 mm (2.5 inches) to prevent contact between stores.
4.3.3.3 Store to suspension clearance.
Same as 4.3.2.3.
4.3.3.4 Trapeze and rotary suspension to aircraft clearance.
There should be 25.4 mm (one inch) clearance between the aircraft (bay structure, bay doors, door actuator systems, hydraulic equipment, electrical equipment, fuel lines, and any other equipment attached to the aircraft bays which the store could contact during captive carriage) and the volume the trapeze or rotary suspension (including the ejection rack) sweeps out during the full translation or rotation operation.
4.3.3.5 Intake duct clearance.
Same as 4.3.2.6.
4.3.3.6 Store arming control system clearance.
Same as 4.3.2.7.
4.3.3.7 Ejection store clearance.
Except for the closed bomb bay doors and side rails, no part of the aircraft nor any other obstructions (except required sway braces, displacing gear, etc., which are automatically removed from their obstructive positions as each store is released) shall lie within the clearance space envelope bounded by the imaginary plane surfaces defined as follows:
a. The plane tangent to the uppermost extremity of the store parallel to the armament roll axis and parallel to the pitch axis of the aircraft as shown on figure 2.
b. Four planes tangent to the foremost, rearmost, right, and left extremities of the store and parallel to the pitch axis of the store at an angle 10 degrees away from vertical, expanding in the direction of the ground as shown on figure 3.
