When I rode jump seat in the cockpit of air carriers the rule was no talking below 10,000 feet.
30 years as an ATC at the busiest single runway airport in the country.
Repeat daily...
Departure..."taxi into position and hold traffic 3 mile final expect immediate departure".
Arrival..."Caution wake turbulence 737 departing just prior to your arrival wind calm".
Always needed to have a plan B.
It's as close to flying as you can get without leaving the ground. lol
Never pursued my pilots license, prefer to do my flying on the ground.
