Ok so there's pressure, density,indicated, true and Absolute.
But the height / velocity curve is all about the height and velocity above the surface, right?
I agree if the air is thinner due to high terrain, that should be taken into account, but the graph does not show this.
So my point is the left side of the graph should depict height, as in vertical distance about the surface. So why does it say ALTITUDE? (especially if there are 5 different types!), and yet the Robinson H/V curve is in HEIGHT as it should be.
I guess MD really mean "ABSOLUTE ALTITUDE" instead of the term "HEIGHT"
