    I mean, airplane brakes probably have about a 3% duty cycle (the percentage of time they’re in use), so they’re generally idle. For city driving, car brakes probably have about a 25% duty cycle.

    If those numbers are close to accurate, that means planes are using their brakes about 10x less than cars.

    BTW, I didn’t pull those plane numbers directly out of my ass, but they’re definitely a rough estimate. I’m figuring about 5 minutes of breaking time per flight, counting landing and during the taxi to and from the runway. And I’m assuming a 2.5 hour flight, figuring that could be close to an average flight time.
