When I started learning to fly, with the Civil Air Patrol just in a Cessna-172 my first instructor was a retired commercial pilot.Aftet some of the first things you learn after ground school in the air after basic flights, are things like, stalls and how to handle spins, and what to do with engine failures/restarts/emergencies like that. You should navigate and assess everything first, then communicate, be it with passengers and ATC. My favorite advice though was, once you are no longer essentisl task-satursted, if ypu are fly a commercial aircraft, and can give a message to passengers, use your best 'Mission Control Houston' NASA tone of voice, nothing will reassure people more than that very calm, collected voice that sounds like everything is going to be fine, no matter what.
