RequirementMethodStatus The payload must not exceed a weight of 1.45 Kgm.Design, Test The payload must conform to the WFF “no volt requirement” Design, Test The payload center of gravity (CG) shall be within 1 cubic inch of the geometric centroid of the payload canister. Design, Analysis The allowable static envelope of the payload is a cylinder with a diameter of 9.2” (23.37 cm) and a height of 9.4” (23.87 cm). Design The payload will record data the entire flightDesign, Analysis
