5.9 System Mounting Interface Loads

PARAMETERMINTYPMAXUNIT
Maximum load to be applied to the electrical interface area(2)1334N
Maximum load to be applied to the Datum A interface area(1)(2)712N
Maximum load to be applied to the thermal interface area(2)200N
(1) Combined loads of the thermal and electrical interface areas in excess of the Datum A load shall be evenly distributed outside the Datum A area (1334+200 – Datum A), or the combined loads of the thermal and electrical areas reduced.
(2) Uniformly distributed within area shown in Figure 5-13.
