What struck me is how relatively simple most of these incidents are to mitigate. Admittedly I may have heard the speaker incorrectly but it sounds like in general getting the pack off at the first sign of odor is the trick to nipping this in the bud. The APU problem seems more insidious. What about a CO detector in the cockpit? Seems fairly easy to do.

Seems we should all have a fairly easy checklist of O2 Masks on, suspected pack off, wait three minutes and check if the smell went away. If not switch packs. It sounded like it is unlikely to be coming from both engines at the same time.

As a guy brand new to the bus I will definitely be keeping this in mind, though it sounds like all planes but the 787 could be susceptible.
