Surface-Effect Hovercraft. Turbine-powered,
surface-effect hovercraft can be fueled on the parking apron
with aircraft direct fueling systems. Use 200 gpm (13 L/s)
maximum fueling rate at 30 psig (207 kPa) nozzle pressure.
The fueling hardware components are similar to those required
for aircraft direct fueling with JP-5, except the fuel
so that the blast generated from the turbine engine does not
damage the direct fueling station components.
READY-ISSUE (OPERATING STORAGE) TANKS. Refer to
Section 8 of this handbook for information and guidelines
regarding operating storage tanks.
Refer to Section 9 of this
EQUIPMENT DESCRIPTIONS. The appropriate guide
specifications and/or standard design will provide specific
information for equipment selection. Make provisions to drain
equipment for maintenance. Provide hard piped drains when the
equipment holds more than 5 gallons (19 L) of fuel or when a
pipe which drains to the product recovery tank is within 12
feet (3.7 m).
Fuel Hoses. Ensure pressure hose connections
between the transfer piping and tank cars, trucks, and vessels
conform to API Bull 1529. Use sizes as required for design
flow rates. For hose flanges and nipples, use carbon steel,
except at aviation turbine fuel issue points, use brass,
stainless steel, or aluminum where metal parts contact the
Positive Displacement. Use flange-connected, cast
steel bodied (except aluminum or stainless steel if after the
desired pressure and flow rating for the applicable service
requirements. Ensure meter has temperature-compensation,
adjustable calibration, register and pre-set capabilities.
Ensure meter accessories are compatible with either the
mechanical or electronic support equipment selected. Provide
an accuracy of plus or minus 0.5 percent when used for custody
transfer. Consult the appropriate Service Headquarters for
