> Ratio of max power to average power is very low on the list of reasons why a gas turbine engined plane needs maintenance more frequently than a piston engined car. I meant for the comparison to be between an internal combustion engine in a car and an air-cooled piston engine in a plane, I should’ve clarified in my post. I’m amazed we even figured out how to make reliable gas turbines (single crystal blades still astound me) so any required maintenance makes sense, they operate at the edge of engineering in a way that most machines don’t.
