This is very very incorrect.
Not a matter of terminology. Regardless of weight , light plane or heavy plane, they will stall at the exact same AOA.

D'oh. I am very very incorrect.
I was going through my experiences with AOA. Both the T-38 and the KC-135 had AOA gauges. The T-38 also had an simple indicator on the glare shield. In both aircraft, the approach speeds were recalculated on every pattern based on aircraft weight. On both aircraft, "in the green" was at .6 AOA.
Then the light bulb came on over my head.
...
As an example stall speed in pilot manuals are normally listed normally listed in IAS. This is because it is most useful to the pilot to know because he can simply look at his air speed indicator and know the number where the plane where stall.
...
It was the
airspeed that changed with weight, not the AOA. The T-38 has a symmetrical supersonic airfoil. The KC-135 had a conventional camber airfoil. Again, both had the same AOA target for approach and landing.
So, mark the date. On this first day of October in the year 2016, I was very, very incorrect.
One unanswered question, why is the scale of AOA on the gauges from 0 to 1.0? It appears to be a ratio. Intuition tells me that the raw AOA for stall should vary with airfoil profile; but, as it has been seen, I could be wrong.
