OPERATING LIMITATIONS
Tail low landings on hard surfaces should be avoided, as stress
damage to the float extensions may occur.
Airspeed Limitations:
Flight with floats inflated, or at time of inflation, is limited to 80 knots
IAS, or basic helicopter V
NE
, whichever is less.
With floats stowed, airspeed limitations are the same as the basic helicop−
ter.
Gross Weight Limitations:
Emergency floats (369H90121−505) on extended landing gear, maximum
gross weight is 2000 pounds.
Flight Limitations:
Night flight over water beyond autorotational capability to ground is prohib−
ited, unless the Night Landing Kit is installed.
Placards:
Float inflation above 80 knots prohibited.
Kit Combination Limitations:
Emergency floats on standard landing gear may not be installed with
369H90062−5 and −6 step assemblies, which are components of the night
lighting kit.
When the 369H90060 passenger step kit is installed in combination with
the emergency floats, the steps must be removed prior to over water flight.
Type of Operation:
Night flight over water beyond autorotation capability to ground is prohib−
ited unless the night lighting light is installed.
Operations with the emergency floats inflated is limited to flight to a servic−
ing facility for repacking and recharging the system. Airspeed with the
floats inflated is limited to 100 knots.
For water and ground landings, change of altitude is limited to 3000 feet
below the altitude at inflation or to 3000 feet below the maximum altitude
to which the inflated floats are subsequently flown.
NOTE
:
If the allowable altitude change noted above is exceeded, the minimum
operational float pressure (3.0 psig) for water and ground landings may not be
available.
CAUTION
