most pilots probably don't know how any specific plane's engine works further than what inputs give what outcomes and a few edgecases. larger aircrafts have most of their functions abstracted away with some models effectively pretending to act like older ones to ship them out faster (commercial pilots have to be certified per plane iirc, so more familiar plane = quicker recertification), which has led to a couple disasters recently as the 'emulation' isn't exact. this is still a huge net benefit as larger planes are far more complicated than a little cessna and much harder to control with all that momentum, mass, and airflow.
