The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.

Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.

Trains used levers for the throttle.
As do many airplanes, in fact Cessna-style plunger throttle controls are relatively unusual.
The knobs on airplane throttles or thrust levers are also seldom spherical; it has happened but most are cylindrical. There's a whole section in FAR 23 that talks about how they have to be oriented in the cockpit, the shape and color of the knobs/handles etc. so pilots can tell them apart at a glance/by feel. For instance, when you first climb into a Cessna Skyhawk the position of the flap lever in front of the copilot's left knee feels kind of strange, almost everything is conveniently placed for the pilot, but the flaps are way over there. law requires the flap control to be to the right of the cockpit centerline, the gear lever must be to the left, but a Skyhawk has fixed gear.
You often hear steam engineers say "put the throttle on the ceiling" meaning apply full power. Diesel engineers will refer to "notch 8" as the highest power setting.
My mom worked for the railroad - she was the first trains woman to become a superconductor.
Probably had a lot of folks railing against her for being a trainsetter
I heard that too

Wow I never knew this either. This is a good one
I guess it makes more sense than slamming your testicals against the wall.
In a way relating to human anatomy that has caused me to remove this phrase from my usage in recent years (because I worried how others would take it) the balls=testicles actually always made sense to me, but I'm not going to explain it.
However, now that I know what the most literal interpretation of the phrase actually is, I can feel safe using it again!
Thank you, thank you, sir or madam
