L/HIRF Protection System Properties

In non-LHSI projects (i.e., projects using one of the MSG-3 guidelines that do not support identification of L/HIRF Significant Items), the L/HIRF Protection System Properties window allows you describe an L/HIRF protection system used in the zone. These systems help to avoid, eliminate or reduce the consequences of a lightning/high intensity radiated field (L/HIRF) event.

To add a new protection system description, choose Zones > L/HIRF Protection > Add Protection System.

The following fields are available:

• General
  • Description: The name and/or description of the protection system.
  • Ref #: The protection system's reference number.
  • Location: The physical place on the aircraft where the protection system is located.
• Components
  • Internal LRU Components: The internal LRU components (line replaceable units) that are part of the protection system.
  • External Components: The external components that are part of the protection system.
• Protection Characteristics
  • Characteristics: The protection system's characteristics that might be susceptible to environmental deterioration and accidental damage.
  • Degradation: The ways that the protection system could be degraded and how the factors that could cause degradation might be detected.
• Other
  • Remarks: Any additional comments about the protection system.

• History provides information about when the record was created and last updated. If the history log has been activated at the project level, you can click the View Item History icon to open the Record History Log for the record.
