Front 3

What is a DFS and how does it effect DLSS equipment?

Back 3

Specifications are engineered requirements such as type of materials,dimensional clearances, electrical values, vibration levels, flow rates and physicalarrangements to which components are purchased, installed, tested and maintained.
All DLSS are designed and constructed to specific technical physical requirements. It isimperative that every effort be made to maintain all systems and components to their
designed specifications. There are, on occasion, those situations in which the applicable specifications can not be met and the system or component is controlled with a departure from specification. To maintain a precise control of any DLSS technical configuration, all deviations must be recorded and approved by the proper recertification authority.
