## 5.1 COMPONENT COMPATIBILITY: 

## 5.2 COMPONENT QUALIFICATION BY GROUP: 

The component manufacturer shall provide a means of determining compatibility and shall provide specific guidance to ensure that form, fit and function of all components, as assembled, are within acceptable limits for each individual component and the assembly as a whole. 

Components may be qualified as a group consisting of a range of scaled sizes. Separate elements of the component design may be linearly scaled at different rates as specified in the component drawings provided that fit, form, and function are not adversely affected. For canopies, the range may consist of scaled sizes to a maximum area of three times the smallest size.
