The Interagency Helicopter Operations Guide Unit (IHOGU) manages the content of the NWCG Interagency Helicopter Operations Guide (PMS 510), which promotes the safe, cost-efficient and effective aviation services in support of agency and interagency helicopter operations. Primary objectives of the guide include:

  • Define and standardize national, interagency helicopter management and operational procedures for helicopter users from participating agencies.
  • Through standardization, facilitate the ability of personnel from different agencies to work cooperatively on incidents or projects.
  • Provide a framework within which areas, regions, states, and local units can provide supplemental site-specific guidance.
