How does "hotel mode" work?

Hotel mode, a unique capability of the C-130J propulsion system that
provides for safer ground loading and unloading operations, was
demonstrated in recent tests at MCAS Cherry Point, North Carolina.
This capability puts the C-130J propellers in feathered position,
which reduces both propeller blast and engine exhaust heat and,
consequently, the amount of dust, dirt, and debris being kicked up
behind the aircraft. The engines remain running in this mode enabling
the pilot to spool them quickly up to military power.
