smoke/fumes removal B737
 

This checklist divides after the initial recall items in a pack(s) on packs off section.

The first part I can figure out, and is a follow up from air conditioning smoke/fumes or electrical smoke/fumes or fire.

The second one I find a bit harder to get, where in the QRH or and inflight emergencies do you turn off the packs off?

and open the window?

any suggestions?

and another thing (maybe my QRH is out of date) why does the "classic" have recall items and the NG not?
