I dont see them neccessary unless you are landing on a aircraft carrier.

I just don't know a lot about them. I understand what they do but they just dont seem neccessary unless you are landing a jet to an aircraft carrier where every bit of precise information is neccessary.

And now I see them on the Cessna 172SP planes.

Long story short. How important they are for aircraft carrier pilots and Cessna students/pilots?

  They can be useful, think about in a level turn, the aoa indicator will tell you how close you are to a stall when additional loading changes your stall speed.

They’re super useful once you get used to them. No matter your weight, if you fly at the right AOA you’ll have the right stall margin. It is easier to see the indexer than the ASI, for control on approach. It acts like a pitch rate indicator too, if you are rough with the nose, so it helps to smooth out the flying. Responds much faster than the ASI. If you are maneuvering aggressively, it will give you that stall margin too.

Accidental stalls are fairly common, especially for new pilots, and that's why we have stall warning devices--and train pilots to immediately recover as soon as they hear/see them. However, simple devices don't tell you anything until you're right on the edge. For more complete information, you need an AOA sensor. Once you have that sensor, why not display that information to the pilot? If you have a glass cockpit, the cost of adding one more data item on the display is pretty much zero, and it might be useful to some pilots--regardless of whether they're flying a trainer, an airliner, or a fighter.
