Section III. TECHNICAL PRINCIPLES OF OPERATION
1-13. OPERATIONS.
a. Overall aircraft fuel management is the
responsibility of the aircraft commander and is
accomplished by utilizing the fuel management control
panel and fuel quantity indicator in the cockpit.
b. The ERFS has capabilities which enable the
aircraft commander to select single or multiple tanks at
his discretion. The transfer of fuel from the 600 gallon
tanks to replenish fuel in the aircraft's main fuel tanks is
accomplished by the operator activating the FMCP
switches. This is a self-contained pumping system
which utilizes the aircraft's 28 V dc UH and R/H utility
receptacles at station 260.
1-14. OPERATING INSTRUCTIONS. Operating
instructions and use of operator controls and indicators
can be found in Chapter 2.
1-15. PERFORMANCE DATA. Refer to Table 1-2.
1-16. SAFETY, CARE, AND HANDLING. Warnings
and cautions are stated as applicable throughout this
manual.
1-17. SAFETY HAZARDS. Installation of the ERFS
increases the exposure of the aircraft and crew to fire
hazards. However, if personnel use reasonable caution
and safety practices as prescribed in this manual, the
ERFS is an airworthy system.
