and 28 GPM (51.3 pounds per second net change). During roll 

 damping operation the rate is controlled proportionally. In eill other 

 modes of operation, maximum rate is used. 



Variation of BG Is accomplished by transferring from the 

 reservoir to the two list tanks. Roll damping is eiccompllshed by 

 transferring between list tanks for list angles less than 22,5 degrees 

 and between reservoir and the appropriate list tank for list angles 

 greater than 22,5 degrees,
