Find the Procedure Guide you want to add to your step in an Aero, Recurring Aero or Template Checklist
Look for the Procedure ID in the View button.
Open the Aero, Recurring Aero, or Checklist Template that you want to add the Procedure Guide to. Type the ID number in either the SOP ID column or the LIB ID column, depending on whether it's a procedure you created on your own (SOP) or a procedure that is part of the Aero Library (LIB).
The procedure will appear as a clickable link in the "Do Task" screen. Either an "i" for an SOP or a book for a LIB.
