SOPs
Coming back to the thread, you'll realize that, more often than not, if a lot of pilots are deviating from the laid down SOPs, then it's probably an indication that it's either impractical or flawed in some way.One needs to find out what those reasons are and change the SOP accordingly if required.
Another parallel document explaining the rationale behind the SOP would help get everyone on board. Or at least allow for some discussion to achieve a better SOP.
Quite a few times checklists/SOPs are influenced by local regulatory requirements or sometimes due to legacy of previous types flown in the company. In either case if the rationale is clear and logical, it's easy to adopt. Of course, a lot of us find it difficult to unlearn a checklist/procedure we followed in a previous company and continue doing it that way in a new setup (except on checkrides maybe!)
