>> "... lower peak power would be needed..."

While it is true that you "nail the throttle" during takeoff in a little general aviation Cessna, the same is not true of jet-powered heavy metal. The big planes that account for most passenger miles are limited by engine noise regulations and scaring passengers, and run the engines at a fraction of peak power during takeoff.

You can find implausible-looking-but-true videos of big ungainly airplanes taking off near the edge of the flight envelope in ways that look very surprising.
