I haven't had a picture ID since I left the commuter airline in New Mexico that I was Chief Pilot at. That ID was issued by the Albuquerque airport authority, per US TSA regulations for air carriers and flight crews and it allowed me onto the airline ramp so I could do my job. It was also accepted by Phoenix Sky Harbor airport authority.
Many US charter and fractional companies issue Flight Crew picture ID's which helps them gain access to the General Aviation ramps at larger airports. However, it does NOT allow them access to the Air Carrier ramps around the terminals.
Does that help answer your question, Frank?
And BTW... the only Dumb Question in aviation is the one that wasn't asked.
