All good points. "c" was handled occasionally by U.S. airlines by having ground school by the master, Dave Gwinn. Honeywell used Dave after his life at TWA. Unfortunately, Dave died too young.
I was trained on weather radar years ago by another master, Archie Trammell. His words ring in my ears decades later as I dodge the CB's.
Of course, next time I take the course I want to raise my hand and ask about those no-seeums in the subtropics.
