decrease? increase?
Alas, can't edit the comment anymore, and probably shouldn't anyway, considering the discussion it sparked.
i am a native and this confuses me constantly.
the windshield wipers in my car change their speed based on a UX showing an in increasingingly long bar. i can never tell if it represents time or 1/time until i futz with it.
Yes, you are right to be confused. You dont know the UX of car. Why did you think this was worth commenting?
> (the one closest to off or auto)
the on/off toggle is separate from the speed dial. there is no obvious (to me) directionality.
American cars in contrast have just one control: it starts with off, then does intervals, finally the shortest interval, then low speed and then high speed.
But your classification of European/American cars isn't accurate either. I drive an Italian car (well, but surprise, it's Fiat Chrysler) and the wiper controls makes sense, like what you refer as "American cars". Search for Mercedes Benz wiper controls on Youtube, that also makes sense. BMW's one is strange, the Ford one looks confusing but I didn't bother to look for a video.
I have driven car where the pictogram meant "amount of rain", the longer bar meaning more rain and therefore a shorter interval.
Thank you. I'll show myself out.
When inspection frequency gets too low, airplanes fail, leading to more frequent inspections.
When inspection frequency gets too high, airlines and authorities decide to save money, leading to less frequent inspections.
So the inspection schedules (somewhat) satisfy Hook's Law, and thus we should expect wavelike oscillations.
[Edit: The system also requires momentum. That's provided by labor unions agreements, maintenance contracts, and the time needed to change regulations.]
Thanks, I'll be waiting for you at the pub.
More often such aircraft are just retired. One defining difference between upstart airlines and "legacy" airlines is that the upstarts generally have new aircraft with lower inspection requirements. An interesting paper would address the inevitable evolution of new airlines as as their airframes age. When do they first try to transition to higher-profit services? When do they hit their first period of labor unrest? I theorize it is a function of aircraft age.
At least a few airlines don't ever buy aircraft. Instead they lease them with the intention of returning them moment they require more frequent inspections.
It's... complicated. Very complicated.
