TM 1-1520-240-10            5-9-1/(5-9-2 blank) SECTION  IX.  ADDITIONAL LIMITATIONS 5-9-1.  Air-to-Ground Towing. Air-to-ground towing operations are prohibited. 5-9-2.  APU Operation. APU operation in flight is prohibited except during emer- gencies. 5-9-3.  Pitot Tube and AFCS Sideslip Port Anti-Icing Limitation. The PITOT switch shall not be on for more than 5 minutes on the ground. 5-9-4.  Windshield Heat. Windshield heat shall not be used above 24_C. 5-9-5.  Single Point Refueling. The maximum rate for pressure refueling is 300 gal/min at 55 psi. 5-9-6.  Extended Range Fuel System (ERFS). WARNING Installing  the  non-crashworthy/non  self sealing ERFS increases the potential for explosion   and   burn   injuries   during   a crash. Therefore, the number of personnel on board the helicopter should be kept to the minimum required to perform the re- quired mission. ERFS operation will be in accordance with existing Air Worthiness Release (AWR). 5-9-7.  Extended Range Fuel System II (ERFS II) The  following  paragraphs  contain  important  operating limits and restrictions that shall be observed during the operation of the ERFS II. Compliance with these limits will  allow  the  operator  to  safely  perform  the  assigned missions and derive the maximum utility from the ERFS II. a. The maximum capacity of one ERFS II tank as- sembly  is  825.5  US  Gallons.    The  usable  fuel  in  one ERFS II tank assembly is 800 US Gallons when single point pressure refueled. CAUTION Trying to pressure refuel the tanks without connecting the vent lines could overpres- surize the tanks.   b. The maximum pressure inside the ERFS II tank should not exceed 5 PSI. CAUTION Conducting   suction   defueling   at   pres- sures  greater  than  minus  11  PSI  could damage  the  internal  components  of  the ERFS II tank assembly. c. The maximum allowable suction defueling pres- sure is minus 11 PSI.
