I'm not exactly sure how it worked in practice, but if it's anything like simple aircraft engines with carbs, there's a mixture control that you'd use in addition to the throttle to control air intake.

When you're engine braking—like when you downshift and let off the gas—the ECU often cuts off fuel to the cylinders. The throttle valve is also closed. In this scenario, your RPMs are maintained by the car's forward motion, which is connected through the drivetrain back to the engine.

So yeah, you're not using any fuel in that case, but you're still turning the engine over. The wheels are essentially driving the engine instead of the other way around. That's how you can have RPMs but no fuel flow during engine braking. The energy to keep the engine turning is coming from the car's inertia.

A common example would be going downhill. You downshift to a lower gear, take your foot off the gas, and let the engine do the work to help slow you down. You'll see the tachometer showing RPMs, but fuel flow is minimal or even cut off, thanks to our friend the ECU.

Any reason why y'all as a community don't like this content? Is it because it's old? I indicated that in the title. I think it captures an interesting historical time and reminds us of things we take for granted now a days.

I'd say this is a lot more niche than Reddit and I'm a lot more likely to have someone in common with other people interested in FOSS/federated networks.

Do you have a graphics card or are you using the extensions on a CPU?

Any one have any information about why the wing came off? Was the pilot maneuvering out of the legal envelope?

I think I like this guide much better:

Sorry, I meant to mention in the scenario that you were already in climb out phase and potentially close to running out of runway if you try to land straight ahead.

One thing I found interesting here was a comment on the YT video from a CFI who taught his students rejected takeoffs using this method to successfully execute them in an emergency setting. However, they did it for a hitting a goose with the wing. Obviously I wasn't there so I couldn't see what happens and make the call, but what are y'alls thoughts on that? It seems like it would be better to keep flying and maybe do a lap in the pattern instead of risking running out of runway and rejecting the take off.

Here's a video with some more related comment. https://www.youtube.com/watch?v=UoMJcOrgcEw
