apexlined Posted November 8, 2010 Share Posted November 8, 2010 Why hydraulic oil for auxiliary system more than utility and booster? Quote Link to comment Share on other sites More sharing options...
tenten Posted November 8, 2010 Share Posted November 8, 2010 Maybe related to the ramp & door actuator cylinders (bigger volume capacity). Quote Link to comment Share on other sites More sharing options...
Dave in WV Posted November 8, 2010 Share Posted November 8, 2010 What tenten said plus the aux system is the emergency nose gear extention system. Quote Link to comment Share on other sites More sharing options...
Guest Posted November 10, 2010 Share Posted November 10, 2010 What tenten said plus the aux system is the emergency nose gear extention system. On tankers, (Sargeant Fletcher Pods) the Aux system also runs the hose reels in emergency. Quote Link to comment Share on other sites More sharing options...
bobdaley Posted November 10, 2010 Share Posted November 10, 2010 A's B's D's F's and 1961 E's used forward cargo door pump for emergency nose gear extension! Bob Quote Link to comment Share on other sites More sharing options...
trectenwald Posted January 28, 2011 Share Posted January 28, 2011 It has a higher capacity mainly for ground handling ( pressurizing utility with aux ). Its common for the door to be open, ramp full open all while the -1 is going on at the same time. As you would imagine, this uses up a large amount of hydraulic fluid. Also, as the others before me have stated, this does operated the emergency systems. Quote Link to comment Share on other sites More sharing options...
