FAA Approved
NOTE
:
To account for anticipated variations in ambient
temperature or water
temperature at a scheduled
landing site, the following procedure should be
used
to maintain the minimum 2. 0 psig inflation
pressure.
For ambient (air) temperature or water temperature colder than the temperature
at initial inflation, float inflation pressure should be increased 0.5 psig (above) the
minimum 2.0 psig) for each 15
°
F decrease in temperature anticipated.
Example:
70
°
F Ambient temperature at time of inflation minus
45
°
F Anticipated water temperature at scheduled
landing sited equals
25
°
F Temperature decrease
Inflation pressure change to account for temperature
change
(25
°
B
15
°
) x 0.5 psig = 0.8 psig
Minimum float inflation pressure for this operation would be
2.0 psig + 0.8 psig = 2.8 psig
NOTE
:
Temperature increase will increase float inflation
pressure and need not be
considered.
Center of gravity (C.G. Envelope):
NOTE
:
The installation of the float kit contributes to
an aft shift of the C.G. For conditions
requiring pilot only operations, ballast will
be required in the utility stowage
compartment
or front seat. The operator should determine
the proper amount of
ballast required to
remain within the aft C. G. limit for the zero
fuel condition .
Placards:
Placards 1, and 2, are required when the utility floats are installed.
