Hoist Operations
When should the hoist brief be conducted and why?
The hoist brief should be completed once onscene, from an orbit or appropriate hover altitude that provides the crew an adequate vantage point to identify hazards and a suitable hoisting area.
When should the vessel brief be conducted and why?
Communications should be established as soon as possible and prior to arriving onscene in order to expedite the rendezvous and hoist.

True or false: With the BACKUP PUMP - ON and the RESCUE HOIST SWITCH - ALL, hoist control is available to pilots and crew, and SHEAR authority is available to all switches.
True
The ____ _______ _________ feature should be used during all hoisting operations to prevent inadvertent heading change.
