aircraft must not be hot refueled until it undergoes at
least one normal (cold) refueling operation to show
that the jettison valves are closed.
Aircraft will not be positioned such that jet exhaust
is directed at another aircraft on the hot refueling
pad.
Temperature sensitive substances (temp sticks)
have caused damage to some aircraft brake assembly
pressure plate antioxidant coatings. Refer to
MDS Specific technical orders for guidance.
NOTE
For simultaneous hot refueling operations, aircraft
will not enter the hot refueling pad unless it can
immediately egress, if necessary. Fire department
must be notified whenever hot refueling is to be
accomplished. Refer to Paragraph 6.4 and Table
3-1.
b. A hot brake check will be performed. The A-10, C-5,
C-17, C-130, C-141, E-4, F-15, and HH-60 aircraft are
exempted because of the location, direction, and distance
of the fuel vent outlets from the aircraft landing
gear brake assemblies. The brake temperature should
not exceed 750 °F. Temperature can be measured by
temperature sensitive substances (temp sticks) or by
infrared heat sensors. The aircraft hot brake checks will
be accomplished prior to entering the hot refueling
area. Aircraft with suspected or known hot brakes will
not enter the hot refueling pad. The external fuel tanks
will be safed prior to entering the hot refueling area.
d. The Hot Refueling Supervisor (HRS) will ensure the
fuel servicing equipment outlet nozzle is connected and
the deadman control valve is hand-held. The HRS will
maintain intercom contact with the pilot plus visual
contact with the hot pad supervisor, hot refueling crewman,
and fuels equipment operator; if capable, the HRS
should also be on intercom with the hot refueling
crewman. The HRS will observe the aircrew to ensure
they maintain their hands up and/or out of the cockpit
instrumentation area.
e. The fuels equipment operator will use standard checklists
developed for preoperative inspection check of the
fuel servicing equipment. Upon pressurization of the
fuel servicing equipment, the equipment operator and
all ground crewmen will check the system for malfunction
or leaks. If no leaks are detected, the ground
crewmen will signal the HRS that fuel transfer can
begin.
f. On aircraft equipped with the capability to pre-check
the refuel high level shutoff valves, the valves will be
prechecked at the beginning of the hot refueling operation.
Malfunction of any component of the fuel servicing
equipment is cause to immediately shut down
the equipment until the defect is repaired.
g. When the fuel servicing is completed, the aircraft fuel
servicing supervisor will advise the pilot that the single
point nozzle and bond wire have been disconnected.
The aircraft HRS will then marshall the aircraft out of
the area.
c. Aircraft systems can be left operating, but do not allow
transmitting on aircraft radar units nor HF radios.
