You say you did not train as crew.
Now you say you are a member of crew but not a crew member.
Tortuous linguistics at best.
As said before, here on PPRuNe we use the definitions commonly used in most airlines around the world.
Cockpit crew = pilots
Cabin crew = flight attendants
Together they form
a crew:
- definition 1: the personnel working aboard a ship or an airplane.
- definition 2: a group of people working together to perform a joint function.
