PART I
GENERAL
The MDHI Emergency Float Kit, consists of inflatable bag−type floats intended
for use in emergency landings only, during over−water operation. It is fur"
nished with squib−actuated valves and with steel pressure vessels.
The floats are normally carried in the stowed configuration, mounted as a com"
pact package on top of each skid. A press−to−test indicator light is provided to
check the condition of the electrical actuation circuits for each float. This indi"
cator is located on the caution and warning indicator panel. The circuit break"
er is located at the bottom of the circuit breaker panel. A recessed switch is
provided on the cyclic stick for the pilot to initiate inflation when required.
The switch activates valves allowing air or nitrogen stored in pressure vessels
within the float packages to inflate the floats.
An optional Night Landing Kit is available consisting of dual belly mounted
sealed beam lights, a circuit breaker, and a three position switch installed on
the collective control. Forward position illuminates the standard nose mounted
landing light; center position is off; and aft position illuminates the belly
lights. Night flight over water is permitted with the night landing light kit in"
stalled.
