Each of the float assemblies, two on each side of the helicopter, are stowed deflated
and folded in compact packages attached to the airframe. The stowed floats are
aerodynamically covered with hard plastic fairings for protection and to minimize drag,
and cause no airspeed penalty. Two floats are mounted under the forward cabin, and
two are attached at the ends of the wings. Compressed dry nitrogen gas stored in a
composite bottle can be released by a dual action valve (electrical / mechanical) into
a manifold piping system to inflate all four floats. The standard location for the gas
bottle is the aft end of the baggage compartment.
The primary (electrical) actuation system consists of four immersion switch assemblies
mounted on the belly of the helicopter. Activation will occur when the system is armed ,
and any two of the switches are submerged in water, a solenoid valve releases the
compressed nitrogen gas, to "pop out" and inflate each of the floats. Arming of the
system is accomplished with a pedestal mounted switch EMER FLOATS, which
illuminates the FLOATS ARMED IIDS advisory message. Arming is required whenever
conducting take off or landings over water, or when operating in close proximity to the
waters surface. A back up mechanical release "T" handle EMER FLOATS PULL is
located on the pedestal for manual pilot activation if the electrical system should fail.
This system is not dependent on electric power, and to prevent accidental activation,
the EMER FLOATS PULL handle is guarded by a spring loaded transparent plastic
cover.
