IHOG is now SHO

Standards for Helicopter OperationsThe book of standards that has governed the use and management of helicopters used by federal land management agencies has changed its name. The 2019 revision of the Interagency Helicopter Operations Guide (IHOG) is now titled Standards for Helicopter Operations (SHO).

The document, “…establishes the standards by which helicopter operations are to be conducted under the exclusive direction and operational control of federal, state and local agencies in the accomplishment of interagency fire suppression and natural resource aviation management.”

The SHO has been adopted by the USFS, BIA, BLM, and NPS as policy for all helicopter operations.

The last edition of the IHOG was published in June of 2016. The new SHO is dated May, 2019 and is expected to be revised in 2022.

Apparently there are no plans to officially print and distribute paper copies of the 319-page book and the four associated documents, but they can be downloaded at the National Wildfire Coordinating Group’s website.

The SHO was produced under the auspices of the NWCG and the National Interagency Aviation Committee, Interagency Helicopter Operations Guide Unit, and Interagency Helicopter Operations Subcommittee.
