- foldr 8y agoAh ok, that make sense.
- FabHK 8y agoThis article from 2013 outlines the differences quite nicely. It's a subtle point (that I hadn't appreciated before reading the article), but trim on a Cessna (on which many pilots learn) and modern jet work quite differently, though you rarely ever notice the difference in normal ops (because you never go massively out of trim). The author speculates that several accidents might be attributable to this. Do you really understand how your trim works? Many do not, and why it matters.

- VBprogrammer 8y agoI only really appreciated this while reading while reading about https://en.wikipedia.org/wiki/Alaska_Airlines_Flight_261 https://en.wikipedia.org/wiki/Alaska_Airlines_Flight_261 It's quite an interesting one if you are into that kind of thing.
- inferiorhuman 8y agoWell an MD-80 does use trim tabs.
- VBprogrammer 8y agoNot really. It trims via a moving stabiliser. You are confused because it has flying elevators and the pilot only directly controls the servo tabs which look a lot like trim tabs.
- inferiorhuman 8y agoAh yes, brain fart. Tabs for the elevator, jackscrew for the stabilizer.
