Airspeed Indication and Relative Wind

Scott, you got 100 percent bad advice in the previous responders.

And you are 100% idiot.

The bottom line is that the indicated airspeed DOES have errors depending on
the angle of attack.

You may well be correct that the error comes mostly from the static port and
not the pitot tube, but a) this is not relevant to the question asked (only
to part of some of the answers), b) hyperbole just makes you look as stupid
as you claim other people are, and c) much of the response the original
poster got was correct (in other words, the advice was NOT "100 percent
bad").

Welcome to the newgroup. You made quite an entrance.

Read my post again. I did not claim that AOA does not affect IAS.
I said that AOA does not affect the pitot to any appreciable degree.
The flow around the static source is another story.

Easy now.

I'd forgotten about the static port and it's position with regard to air
flow. Although my original question focused on the pitot tube, it's
undoubtedly better to consider the entire pitot-static system when
considering the effect of different angles of attack on IAS.

So, if I slip to the right during the aforementioned steep approach and
the static port is on the forward left side of the fuselage, the static
pressure goes up a little bit, I suppose? Then, combining a slightly
lowered pressure at the pitot (due to AOA) plus a slightly higher
pressure at the static port, I get a lower IAS, right?

I realize the total error is still probably negligible. Just armchair
flying.

Sure you did. When you wrote "you got 100 percent bad advice".

The only way that the responses to Scott's posts could have been "100
percent bad advice" would have been if there was no effect on the IAS due to
AOA.

Do you actually know what "100 percent" means?
