Possible Failure Modes:
Failure Mode | Probability | Severity | Mitigation |
AV Bay structure fails to support weight of electronics | Low | High | Use aluminum bottom bulkhead and fiberglass mounting plates |
Metal interferes with electronics or antennas | Medium | Medium | Proper placement of components on mounting plates, multiple ground stations |
Vibrations create issues with electronics | Low | Medium | Use vibration damping attachments for mounting plates |
