Chapter 11: Communication & Navigation › Installation of Communication & Navigation Equipment › Vibration Isolation
amplitude and frequency of vibration of the aircraft structure will vary considerably with the type of aircraft. Avionics equipment is sensitive to mechanical shock and vibration and is normally shock mounted to provide some protection against in-flight vibration ... landing shock. Special shock mounted racks are often used to isolate avionics equipment from vibrating structure. [Figure 11-158] Such mounts should provide adequate isolation over the entire range of expected vibration frequencies. When installing shock mounts, assure that…

Each installation should also be planned to allow easy access for inspection, maintenance, and exchange of units. The installation of avionics equipment is partially mechanical, involving sheet metal work to mount units, racks, antennas, and controls. Routing of the interconnecting ... cables, antenna leads, etc. is also an important part of the installation process. When selecting a location for the equipment, use the area(s) designated by the airframe manufacturer or the STC. If such information is not available, select…
