SOP 2 has "Rudder and Aileron Trim - FREE AND ZERO" as part of the Before Start checklist. But the FO doesn't pressurize the hydraulics until after the checklist is complete, so I'm not sure how to actually check that the aileron trim is free. Am I missing something?

In the Capt's (that's you) preflight flow, hydraulics are turned on.

Remember in SOP3, the user (the Capt/PF) does most of the work.  It's his or her show.

 

Did you mean to say SOP2? Because I am using SOP2. The FO does turn on the hydraulics after I complete the below-the-line check.

Why was thinking of SOP 3? Getting old hahaha

Maybe Dean can chip in if he's reading this.  He wrote the script for SOP2 based off his old airline he flew for.
