If there are operators who do not set the Pumps ON until refueling finishes , it might be because of issues that resulted because of that , and I would like to be informed about it . My Previous operator had this as SOP with no explanation ( their entire OMB -SOP was the exact FCOM-SOP written with their own minor modifications so we very seldom bothered with the FCOM SOP. ) Now that I’m with a different operator I’d like to be sure exactly when I raise a topic , to have valid justifications for it .
