Are they to be considered crew members in case of calamities?

Maybe management pilots were considered observers not crew members. Although the FOM clearly stated that company pilots needed only a pilot cert and badge, but no medical.

But you can also do flight instruction without a medical, as long as the legally required crew compliment is present and qualified.

At Southwest, our sim instructors are not on our seniority list and by our contract, they aren't allowed to conduct any checking events - only training, and a good number of them no longer have their medical.

Our sim instructors have regular access to our jumpseats.

Looks like each company can decide who uses their own jumpseats...but what about using a different company's jumpseat.
