    The GAD 29/29B and GAD 13 are the LRUs installed by this STC that require chassis bonding. Sections 4.5, 4.5.1, 4.5.2, 4.5.3 present data on acceptable methods of electrical bonding for the GAD 29/29B and GAD 13. For G5 and GMU 11 bonding strap requirements and associated installations, refer to section 4.5.4 and 4.5.5.
  • Page 99 The instrument panel must be of metal construction so that remotely mounted units have a metal ground reference back to the other G5 interfacing equipment mounted on the instrument panel. For metal aircraft the latter is achieved inherently through the metallic aircraft structure. For composite aircraft a ground plane (or reference) may need to be created to achieve a comparable ground.
